Classification & Species
All crabs are classified as decapods: a crustacean with five pairs of legs on the upper half of their body. At least one of these appendages will be modified into a pair of pincers or claws. They have stalked eyes, and their head and thorax fused together, covered by a carapace.
Mating
Crabs mate directly after they’ve molted while at higher risk of predation. When a crab molts, its hard outer shell comes off and is replaced by a soft shell that has newly developed underneath.
Life Cycle
Crabs all have the same basic life cycle. Specifics may vary between species, but they are all born and develop in the same way.
Diet
The diets of crabs differ between each kind of crab and where it lives.
Natural Predators
While crabs are protected with a hard shell surrounding their body, they are still at risk of predation. Some bigger, more aggressive fish like bass, halibut, cod, and sharks will all easily make a meal of a tasty crab.
Habitat, Migration, & Range
Different kinds of crabs can be found all over the world. They can be found in freshwater, saltwater, and brackish water regions, with some species inhabiting cold waters, and others warm. Some crabs even live on land.
Impact of Climate Change
The effects of climate change are affecting every living species on the planet, and crabs are no exception. George Somero, the director and professor of Stanford’s Hopkins Marine Station says that the warming of ocean temperatures has drastically impacted the populations of crabs in the Pacific Ocean.

What is a walrus' flipper?
Flippers are hairless. The skin on the soles of a walrus's flippers is thick and rough, providing traction on land and ice. The foreflippers, or pectoral flippers, have all the major skeletal elements of the forelimbs of land mammals, but are shortened and modified. A walrus's foreflippers are short and square.
What does a walrus do when swimming?
While swimming, a walrus holds its foreflippers against its body or uses them for steering.
How many vibrissae does a walrus have?
A walrus has about 400 to 700 vibrissae (whiskers) in 13 to 15 rows on its snout. Vibrissae are attached to muscles and are supplied with blood and nerves.
Why are walruses pink?
They are pink in warm weather when tiny blood vessels in the skin dilate and circulation increases. This increased skin circulation sheds excess body heat.
How big are walruses?
Atlantic walruses are slightly smaller: males weigh about 908 kg (2,000 lb.) and reach lengths of 2.4 m (8 ft.). The northern and southern elephant seals are the only pinnipeds that, when full-grown, can be larger than the walrus.
How big are Pacific walruses?
Male Pacific walruses weigh about 800 to 1,700 kg (1,764-3,748 lb.) and are about 2.7 to 3.6 m (9-12 ft .) long.
How thick is a walrus' skin?
Skin and Hair. A walrus's skin is thick and tough. It may reach a thickness of 2 to 4 cm ( 0.79-1.6 in). It is thickest on the neck and shoulders of adult males, where it protects the animal against jabs by the tusks of other walruses. The skin of males often has large nodules; these are absent in females.
What is the tail flick test?
It is one of the most common tests based on a phasic stimulus of high intensity. There are two variants of the tail-flick test. The first consists of immersing the tail in water at a predetermined temperature, and the second is to apply radiant heat to a small area of the tail. Although apparently similar, the two methods differ in terms of the stimulated surface areas. Compared to other nociceptive methods, the tail-flick method is simple to perform but animals should be accustomed to being handled so that they remain calm during measurements.
What is the Hargreaves assay?
The Hargreaves assay is similar to the tail flick assay , but the high-intensity beam of light is aimed at the rodent’s hind paw rather than the tail. The investigator measures the time it takes for the rodent to withdraw its paw.
How does a tail flick test work?
In the tail-flick test, the animal is briefly restrained, with its tail extended on a flat surface. A heat stimulus of fixed intensity is applied to the cutaneous skin of the tail (usually from below), and the time required for the animal to flick (i.e., withdraw) its tail from the stimulus is recorded.
What is the ability to detect a noxious stimulus, usually perceived as pain?
Nociception is the ability to detect a noxious stimulus, usually perceived as pain. Nociceptive assays rely on physical indicators of discomfort, such as withdrawal reflexes, licking, and vocalizations. These assays are usually used to investigate either the neural basis of pain or the therapeutic potential of analgesic drugs. Genetically or pharmacologically manipulated animals that exhibit decreased sensitivity to pain must be monitored closely during these assays to prevent tissue damage induced by nociceptive stimuli.
Which mice have the strongest SIA?
Interestingly, the heterozygous COMT knock-out mice showed the strongest SIA. A similar paradoxical over-activity, compared with the wild-type mice, has also been seen in some earlier studies in some other behavioral tests ( Gogos et al., 1998; Huotari et al., 2002b, 2004; Männistö and Kaakkola, 1999 ). Hence, it is obvious that more than 50% lack or inhibition of COMT is needed for significant actions. Besides Comt gene disruption, such profound effects can be obtained by high doses of COMT inhibitors ( Männistö and Kaakkola, 1999 ).
What is a Von Frey assay?
A Von Frey assay is used to examine the sensitivity to pinch and mechanical stimuli. Von Frey hairs are fine-gauge metal wires. The investigator pokes the hind paw of an animal standing on an elevated mesh platform by inserting a Von Frey hair through the mesh from below. Normal rodents usually react by withdrawing or licking their paws and possibly vocalizing.
Does epibatidine increase noxious thresholds?
After adrenal medullary (but not control) transplantation, nociceptive thresholds to acute noxious stimuli were modestly but consistently elevated ( Figure 26.3 ). Following intrathecal injection of epibatidine, acute nociceptive response latencies were only marginally elevated in control animals at the highest dose test, with some attendant motor side effects. In contrast, in adrenal medullary transplanted animals epibatidine markedly elevated responses to acute noxious stimuli in a dose-related fashion ( Figure 26.3 ). Similar potent and enhanced antinociceptive effects of epibatidine in adrenal (but not control) transplanted animals were observed using the formalin test [ 12 ].
What are claws used for?

How long are a squirrel's claws?
These large mammals have long claws about 2-4 inches long, especially those claws in its front paws are relatively longer than its hindlimbs paws. These front claws aid in digging roots, ground squirrels, and penetrating through fruits. These sharp and pointed claws also enable them to catch prey such as fishes as they provide firm grips.
How big are sloth bear claws?
An adult sloth bear has large, thick, and sickle-shaped, blunt claws about 3 inches long that they primarily use for digging termite and ant mounds. Like other bears these bears can’t climb trees as its claws are less adapted for climbing.
