Some salamanders such as Axolotls and Sirens Sirenidae, the sirens, are a family of aquatic salamanders. Family members have very small fore limbs and lack hind limbs altogether. In one species, the skeleton in their fore limbs is made of only cartilage. In contrast to most other salamanders, they have external gills bunched to…Sirenidae
Can you keep a salamander as a pet?
You can keep a salamander as a pet. They generally make great pets and can live for a minimum of 6-10 years as long as you take proper care of them. You will need to consider their unique needs and preferences and ensure you optimize their habitat, diet, and refrain from handling them.
What is the life cycle of a salamander?
With time, as the tadpoles grow and metamorphose into Salamanders, their external wing-like structure shreds off. Salamander Life Cycle Life Span Various species of these amphibians have various duration of longevity. On average, Salamanders live for about 20 years. Some species might even live up to 50 years.
What are salamanders habits?
Salamanders are fascinating creatures with interesting diets. The dietary habits of salamanders vary according to the species. Most live on dry land. Others are aquatic and rely on gills. Newts and sirens are both aquatic salamanders. The diets of these two species are not the same. Depending on their habitat, salamanders may eat insects or…
Do salamanders live underwater?
Salamanders live in waterand on land, and look rather like lizards, with four legs and a tail. They hatch as larvae from eggs in the water. At that stage, they have gills that stick out. Most salamanders liveon land when they are adults, after their change of shape (metamorphosis).
Can a salamander survive underwater?
They don't have hind legs at all! Their long, strong tails are flat to help sirens swim like a fish, with the tail flapping from side to side. Different members of the salamander order have developed different ways of breathing. Sirens keep their gills all their lives, which allows them to breathe underwater.
Do salamanders breathe underwater?
Some salamanders, such as axolotls and sirens have gills and can breathe underwater. Others as the tiger salamander, have lungs to breathe air and only have a very limited ability to breathe underwater. Most salamanders go through three distinct life stages. They begin their lives as tiny larvae with feathery gills.
Do salamanders need to live in water?
No matter the species, all salamanders need to keep their skin moist and need to have offspring in water, so a nearby water source is critical. Most species live in humid forests, though there are some exceptions.
Do salamanders swim underwater?
Some Salamanders Are Fully Aquatic These salamanders do not lose their gills when they develop into adults, so they can breathe underwater just like fish. They also have a flat fin-like tail making them very efficient swimmers. Some normally terrestrial salamanders can also develop to be fully aquatic.
How long can a salamander stay underwater?
Depending on several factors, salamanders can stay underwater anywhere from a few seconds to as long as 6 hours. Some salamander species such as the red-backed salamander have no aquatic larval stage. They hatch from eggs laid on land and live a fully terrestrial life from day one.
Do salamanders bite?
Do Salamanders Bite? Yes, salamanders can bite, though they rarely do, as they are timid and tend to avoid confrontation. In most cases, the amphibian will only bite if it mistakes your hand for food. While their small teeth rarely penetrate the skin, clean the wound immediately and monitor for signs of an infection.
Can I put a salamander in my fish tank?
Use an aquarium or tank to house your salamander or newt. You should use a 10-gallon tank, as this will provide enough room for your pet to hide, dig, and sleep. Aquariums tanks are best used for aquatic and semi-aquatic salamanders and newts as they can hold enough water to accommodate their life-style.
Can I keep a wild salamander as a pet?
While newts and salamanders make great pets from an observatory point of view, they are not partial to being handled and can be described as “hands-off pets.” They have extremely delicate skin that can easily be damaged with handling, which can cause potential infections from bacteria.
Are salamanders friendly?
They are not animals that enjoy interacting with humans, though, and very few salamanders will appreciate being regularly handled. They do not make cuddly pets, but they can be a lot of fun to watch as they interact with their environment.
What do salamanders turn into?
The eggs hatch and develop into larvae—tadpoles in frogs and “efts” in salamanders. But occasionally amphibian development takes an odd turn. Sometimes larvae mature to a reproductive stage without undergoing the normal process of metamorphosis for a land-based adult life.
Why are salamanders in my pool?
They usually find their way into pools because their habitats are destroyed or modified and they need to move. This is a problem for the poor thing if the water is treated with chlorine. I would remove it and take it to a local recuperation center, where they will care for it until it can be rehomed.
Do axolotls turn into salamanders?
The tiger salamander and axolotl are related, but the axolotl never metamorphosizes into a terrestrial salamander. However, it's possible to force an axolotl to undergo metamorphosis. This animal looks like a tiger salamander, but the metamorphosis is unnatural and shortens the animals lifespan.
What salamanders live on land?
Salamanders come in three types: terrestrial, aquatic and semi-aquatic. Terrestrial salamanders live on land but congregate in water to breed. Aquatic salamanders spend their whole lives in water. Semi-aquatic salamanders spend part of their adolescence on land and return to water to reproduce.
What do salamanders need to survive?
Salamanders prefer a moist, damp habitat with ample places to hide. You can put your salamander in a plastic container with a tight lid. Drill some holes on the side for ventilation and place the container in an area that doesn't get direct sunlight. Cover the floor with bark chips, potting compost or moss.
Can Axolotls live on land?
The axolotl is a kind of amphibian, specifically a salamander, that does not metamorphose naturally. Usually, amphibians have gills and live underwater when they are young, but then they lose their gills, develop lungs, and live on land as adults.
Can salamanders walk on land?
Salamanders and newts usually move very slowly, although they can run quickly to get away from danger. Normally they walk or crawl—on land, underground, in trees, or on the bottom of ponds. In many salamander species, alternate legs on opposite sides of the body move at the same time.
Where are salamanders found?
Salamanders are found only in the Holarctic and Neotropical regions, not reaching south of the Mediterranean Basin, the Himalayas, or in South America the Amazon Basin. They do not extend north of the Arctic tree line, with the northernmost Asian species, Salamandrella keyserlingii occurring in the Siberian larch forests of Sakha and the most northerly species in North America, Ambystoma laterale, reaching no farther north than Labrador and Taricha granulosa not beyond the Alaska Panhandle. They had an exclusively Laurasian distribution until Bolitoglossa invaded South America from Central America, probably by the start of the Early Miocene, about 23 million years ago. They also lived on the Caribbean Islands during the early Miocene epoch, confirmed by the discovery of Palaeoplethodon hispaniolae, found trapped in amber in the Dominican Republic. However, possible salamander fossils have been found in Australia at the Murgon fossil site, representing the only known salamanders known from the continent.
What is a salamander?
For other uses, see Salamander (disambiguation). Salamanders are a group of amphibians typically characterized by a lizard -like appearance, with slender bodies, blunt snouts, short limbs projecting at right angles to the body, and the presence of a tail in both larvae and adults.
Why do salamanders live in fire?
When the log was placed into a fire, the salamander would attempt to escape, lending credence to the belief that salamanders were created from flames.
How do salamanders catch their prey?
A terrestrial salamander catches its prey by flicking out its sticky tongue in an action that takes less than half a second. In some species, the tongue is attached anteriorly to the floor of the mouth, while in others, it is mounted on a pedicel. It is rendered sticky by secretions of mucus from glands in its tip and on the roof of the mouth. High-speed cinematography shows how the tiger salamander ( Ambystoma tigrinum) positions itself with its snout close to its prey. Its mouth then gapes widely, the lower jaw remains stationary, and the tongue bulges and changes shape as it shoots forward. The protruded tongue has a central depression, and the rim of this collapses inward as the target is struck, trapping the prey in a mucus-laden trough. Here it is held while the animal's neck is flexed, the tongue retracted and jaws closed. Large or resistant prey is retained by the teeth while repeated protrusions and retractions of the tongue draw it in. Swallowing involves alternate contraction and relaxation of muscles in the throat, assisted by depression of the eyeballs into the roof of the mouth. Many lungless salamanders of the family Plethodontidae have more elaborate feeding methods. Muscles surrounding the hyoid bone contract to store elastic energy in springy connective tissue, and actually "shoot" the hyoid bone out of the mouth, thus elongating the tongue. Muscles that originate in the pelvic region and insert in the tongue are used to reel the tongue and the hyoid back to their original positions.
Why do salamanders have tail autotomy?
Some salamander species use tail autotomy to escape predators. The tail drops off and wriggles around for a while after an attack, and the salamander either runs away or stays still enough not to be noticed while the predator is distracted. The tail regrows with time, and salamanders routinely regenerate other complex tissues, including the lens or retina of the eye. Within only a few weeks of losing a piece of a limb, a salamander perfectly reforms the missing structure.
What is the name of the group of amphibians that have a lizard-like appearance?
Salamanders are a group of amphibians typically characterized by a lizard -like appearance, with slender bodies, blunt snouts, short limbs projecting at right angles to the body, and the presence of a tail in both larvae and adults. All 10 present-day salamander families are grouped together under the order Urodela. Salamander diversity is highest in the Northern Hemisphere and most species are found in the Holarctic realm, with some species present in the Neotropical realm .
How big is a salamander?
Salamanders range in size from the minute salamanders, with a total length of 27 mm ( 1. +. 1⁄8 in), including the tail, to the Chinese giant salamander which reaches 1.8 m (6 ft) and weighs up to 65 kg ( 145 lb). Most, however, are between 10 and 20 cm (4 and 8 in) in length.
Salamanders Have Different Ways of Breathing at Different Stages of Their Life
As I mentioned earlier, the majority of salamanders go through 3 life stages. Female salamanders lay jelly-covered eggs and attach them to vegetation in breeding bonds.
Some Terrestrial Salamanders Can Breathe Underwater
Adult terrestrial salamanders primarily breathe in two ways: Through their lungs, or their skin.
How Long Can a Salamander Stay Underwater?
How long a salamander can stay underwater depends on how much oxygen it can absorb from the water.
Can a Salamander Drown?
Even with their ability to breathe underwater through their skin, salamanders can drown. If a salamander stays in water with low oxygen for too long or gets into water so deep that it can not get out, it can drown.
Frequently Asked Questions
Answer: Newts, just like salamanders can breathe underwater by absorbing oxygen that comes in contact with their skin. Their skin has a large network of blood vessels, that allow oxygen in the water to diffuse directly into their bloodstream.
Conclusion
Salamanders are amphibians, so they are always either aquatic (they live in water), or semi-aquatic (they live both in the water and on land). In both of these environments, they have unique ways of breathing. Aquatic salamanders either have feathery gills or very wrinkly skin with a large surface area.
How to keep a salamander in a tank?
Keep a part of water body in the tank and some portion of it as land. Provide enough vegetation inside the tank for them to climb and play. They do not prefer much light as they are nocturnal, so keep them in partial shade and no lights should be inside the tank. Salamander As Pets.
What is the unique feature of a salamander?
Caudata. Types of Salamanders. The only unique feature that they possess being a vertebrate is their ability to reproduce their lost body parts. The amphibian class of Newts is also a part of the Salamanders.
What is the life cycle of a tadpole?
Life Cycle. The tadpoles have external gills in wing-like forms attached to either side of their heads, just where they should have their necks. With time, as the tadpoles grow and metamorphose into Salamanders, their external wing-like structure shreds off. Salamander Life Cycle.
What are the extinct species of salamanders?
The extinct species are grouped under Caudata and the extant ones are grouped as Urodela. All of the species under the genus of Salamander have almost similar physical appearance and prefer similar habitats as well as many habits.
How much does a salamander weigh?
Weight: On average salamanders weigh between 120 gm and 200 gm. Giant salamanders weigh up till about 63 kg. Color: Various different species and sub-species of Salamanders have different colors. Their color range varies from red, black, blue, yellow, orange to many other shades.
How many toes does a salamander have?

What do squid have on their heads?
Head: They have triangular shaped heads with a wide mouth and two eyes on the sides of their heads. They have tiny, sharp teeth on their jaw border. There are no external ears in them, although vestigial middle ears are present.
How Can A Salamander Breathe Underwater?
Salamander is a lizard-like amphibian. Do you know that “amphibian” means double life? Because they can live part of their lives in water and another share on land. Consequently, salamanders are also no exception.
Why do salamanders have a mucous membrane?
That’s why, they have a thin, mucous membrane in their mouth and throat. This membrane can extract oxygen from the water.
What is the medium of respiration for salamanders?
Salamander’s other medium for respiration is their skin. Usually, lungless salamanders breathe through their skin.
How many groups of salamanders are there?
Because this will denote their respiratory organs. By this, we can divide salamanders into three groups.
What is the breathing system of salamanders called?
That’s why, this kind of breathing system of salamander is called cutaneous respiration.
Do salamanders breathe with their gills?
Among these three groups, aquatic salamanders never leave the water. Thus, they always breathe with their gills.
Do salamanders have blood vessels?
Scientists found out that salamanders’ anatomy is quite different from other amphibians. There’s the presence of such blood vessels. Besides, in the case of other animals, it goes to the lungs. But, in the case of salamanders, it goes to the skin.
Where do salamanders live?
Since salamanders need to stay cool and moist to survive, those that live on land are found in shady, forested areas. They spend most of their time staying out of the sun under rocks and logs, up in trees, or in burrows they’ve dug in the damp earth. Some seek out a pool of water where they can breed and lay their eggs before returning to land. Others, like sirens, olms, and axolotls, spend their entire lives in the water.
How many salamanders live in caves?
Others, like sirens, olms, and axolotls, spend their entire lives in the water. There are 16 cave-dwelling salamanders. They have very pale skin, greatly reduced eyes, and have adapted to living in complete darkness in underground pools of water. The Kaiser’s spotted newt defies typical amphibian habitat.
Why are salamanders bold?
The bold color tells predators that the newt is not safe to eat. Many salamanders have glands on the back of the neck or on the tail. These glands can secrete a poisonous or bad-tasting liquid. Some salamanders can even shed their tail during an attack and grow a new one later. The ribbed newt has needle-like rib tips.
How many legs does a salamander have?
Most salamanders are small, and few species are more than 6 inches (15 centimeters) long. Sirens have only two legs, but the other salamander species develop four legs as adults, with fleshy toes at the end of each foot. Some species, like paddle-tail newts, have fully webbed feet with very short toes for their aquatic lifestyle.
What is the name of a salamander that has lungs?
The term "newt" is sometimes used for salamanders that spend most of each year living on land. The name "siren" is generally given to salamanders that have lungs as well as gills and never develop beyond the larval stage. Other names salamanders go by include olm, axolotl, spring lizard, water dog, mud puppy, hellbender, triton, and Congo eel.
What is the name of the group of amphibians that have tails as adults?
The word "salamander" is the name for an entire group, or scientific order, of amphibians that have tails as adults. This includes amphibians commonly known as newts and sirens. Most salamanders look like a cross between a lizard and a frog. They have moist, smooth skin like frogs and long tails like lizards.
Where do Kaiser's Newts live?
This endangered species, also known as the emperor spotted newt or Iranian harlequin newt, lives in the Zagros Mountains of western Iran. It is found in streams and pools surrounded by arid scrubland, where water is only present for three or four months a year. Not exactly the shady, humid place you’d expect to find a newt! In late March and early April, when it begins to rain and the streams and pools fill up, Kaiser’s newts emerge to feed heartily and then find a mate. After this burst of activity, summer arrives, and they head underground, burrowing into the sandy soil and entering a state of torpor in which their heart rate and breathing slow, and they do not eat.
Overview
Description
The skin lacks scales and is moist and smooth to the touch, except in newts of the Salamandridae, which may have velvety or warty skin, wet to the touch. The skin may be drab or brightly colored, exhibiting various patterns of stripes, bars, spots, blotches, or dots. Male newts become dramatically colored during the breeding season. Cave species dwelling in darkness lack pigmentation and have a translucent pink or pearlescent appearance.
Feeding and diet
Salamanders are opportunistic predators. They are generally not restricted to specific foods, but feed on almost any organism of a reasonable size. Large species such as the Japanese giant salamander (Andrias japonicus) eat crabs, fish, small mammals, amphibians, and aquatic insects. In a study of smaller dusky salamanders (Desmognathus) in the Appalachian Mountains, their diet includes earthworms, flies, beetles, beetle larvae, leafhoppers, springtails, moths, spiders, grasshop…
Defense
Salamanders have thin skins and soft bodies, and move rather slowly, and at first sight might appear to be vulnerable to opportunistic predation. However, they have several effective lines of defense. Mucus coating on damp skin makes them difficult to grasp, and the slimy coating may have an offensive taste or be toxic. When attacked by a predator, a salamander may position itself to make t…
Distribution and habitat
Salamanders split off from the other amphibians during the mid- to late Permian, and initially were similar to modern members of the Cryptobranchoidea. Their resemblance to lizards is the result of symplesiomorphy, their common retention of the primitive tetrapod body plan, but they are no more closely related to lizards than they are to mammals. Their nearest relatives are the frogs and toads, within Batrachia. The earliest known salamander fossils have been found in geological de…
Reproduction and development
Many salamanders do not use vocalisations, and in most species the sexes look alike, so they use olfactory and tactile cues to identify potential mates, and sexual selection occurs. Pheromones play an important part in the process and may be produced by the abdominal gland in males and by the cloacal glands and skin in both sexes. Males are sometimes to be seen investigating potential mates with their snouts. In Old World newts, Triturus spp., the males are sexually dimorp…
Conservation
A general decline in living amphibian species has been linked with the fungal disease chytridiomycosis. A higher proportion of salamander species than of frogs or caecilians are in one of the at-risk categories established by the IUCN. Salamanders showed a significant diminution in numbers in the last few decades of the 20th century, although no direct link between the fungus and th…
Taxonomy
Disagreement exists among different authorities as to the definition of the terms Caudata and Urodela. Some maintain that the Urodela should be restricted to the crown group, with the Caudata being used for the total group. Others restrict the name Caudata to the crown group and use Urodela for the total group. The former approach seems to be most widely adopted and is used in this article.
