Spadefoot Toads spend most of their time underground!
What do spadefoot toads eat?
The adult spadefoot toad is an opportunistic hunter that can subsist on whatever small invertebrate it can find, including flies, spiders, crickets, moths, earthworms, centipedes, termites, and snails. Given how little time they spend above the surface, the spadefoot toad is a master of conservation. It can survive for long periods without food. Prime hunting hours occur on rainy or humid nights.#N#Before its full metamorphosis, the spadefoot tadpole can switch between a largely omnivorous diet (feeding on plant matter and small critters) and a full carnivorous diet (feeding on larger invertebrates). When food is in particularly short supply, the carnivorous tadpoles can consume members of their own species. There is a certain discriminatory logic to their cannibalistic habits. When given a choice, they seem to be more predisposed to eating strangers than members of their own kin. As explained in more detail below, the tadpole’s diet seems to induce significant morphological changes.
How long can a spadefoot toad stay in the ground?
Since it only comes out to forage and reproduce, the spadefoot toad can spend the majority of its entire life embedded in the ground. Some reports indicate that it can safely spend months hidden away.
How long does it take for a spadefoot toad to mate?
The spadefoot toad is in no rush to mate. It can go months, even years, at a time without reproducing. However, once the adequate conditions have been met, the toads will congregate in the shallow ponds of their nearby habitat and breed. Because it has such a narrow window of a few days or weeks to fully complete the breeding process before the pools dry up again, a single female can lay clutches of hundreds of eggs. This strategy is known as explosive breeding.#N#Largely left to fend for themselves, the spadefoot tadpoles develop in much the same hurried manner. Although the exact development time varies between species, it may take as little as one day to hatch and two weeks to fully complete its metamorphosis. This development time is faster than almost any other known amphibian.#N#The tadpole stage exhibits a wide range of morphological variation. When the tadpoles first hatch, they have standard-sized jaw muscles and mouths that are well-suited for an omnivorous diet. However, depending on the living conditions of their pond, the tadpoles can switch to a carnivorous diet, which means it will develop a bigger head, smaller gut, and a mouth particularly adapted for predation. One of the more astonishing facts about the spadefoot toad is that tadpoles can regress back to the omnivorous morphology in the absence of larger prey.#N#These morphological changes have an effect on the toad’s behavior as well. While the omnivorous tadpoles congregate in groups, the carnivorous tadpoles tend to be more socially solitary. They also tend to develop more quickly.#N#The expected lifespan of a fully-grown spadefoot toad can vary between species, but it has been known to survive at least 12 years in captivity. This is a typical age for many species of frog and toad.
What are the two branches of the spadefoot toad?
Taxonomists once classified every species of spadefoot toads as a member of a single family called Pelobatidae, but the geographical distribution of the spadefoot toad heavily supports the idea that there are two different branches: the American and European spadefoots. Their distinct evolutionary origins and physical characteristics eventually forced taxonomists to rethink the classification, and so the spadefoot toad was split up into two different families.#N#The scientific name for the family of American spadefoot toads is Scaphiopodidae, which derives from the Greek terms for spade (skapheion) and to dig (skaptein). The American spadefoot family comprises two distinct genera and seven species: the New Mexico spadefoot, the Couch’s spadefoot, the Great Basin spadefoot, the Hurter’s spadefoot, the Plains spadefoot, the Western spadefoot, and the Eastern spadefoot.#N#The European spadefoot family, which still goes by the name of Pelobatidae, comprises only a single extant (or living) genus. This group contains at least four living species, the most common of which is simply called the Common spadefoot. The other three species are the Syrian spadefoot, the Western spadefoot, and the Moroccan spadefoot. Each species roughly corresponds to a different geographical region.
What is the substance in a spadefoot toad's leg?
The spadefoot toad has a large bone-like protrusion in its leg that consists of keratin — the same substance as nails, horns, feathers, and hair.
Where do spadefoot toads live?
Spadefoot toads are generally found in arid climates, where they spend the majority of their lives underground, generally beneath perennial ponds, creek beds, or other moisture-retaining areas. During years of sufficient rainfall, the toads surface to breed and lay eggs.
Where are the American spadefoot toads from?
American spadefoot toad. The Scaphiopodidae are a family of American spadefoot toads, which are native to North America. The family is small, comprising only seven different species. The American spadefoot toads are of typical shape to most fossorial (or burrowing) frogs. They are round, with short legs and protruding eyes.
What do toads eat?
The adults' diet consists of invertebrates. They eat flies, crickets, caterpillars, moths, spiders, centipedes, millipedes, earthworms, and snails. The tadpoles' diet is related to its surroundings and food supply. When they are first hatched, they eat plankton. After a few days, they become carnivorous and eat animals. Tadpoles sometimes resort to cannibalism to survive. After multiple experiments, Paul Székely, Marian Tudor, and Dan Cogalniceanu concluded that tadpole development is influenced by hydroperiod, or the period in which an area is full of water. Since American spadefoot toads breed in shallow waters, they are under “constant stress from drying waters, increasing temperatures, reduced food densities, and crowding”. This stress, or simply a lack of adequate food, can increase the likelihood of cannabalism. If they do resort to cannibalism, their bodies can transform. They “develop larger heads, sharp beaks, stronger jaw muscles, and shortened intestine”. Researchers have concluded that this is an adaptive trait because it accelerates the rate of growth of the tadpoles by allowing for an increased caloric intake.
Why do spadefoot toads breed in shallow water?
Since American spadefoot toads breed in shallow waters, they are under “constant stress from drying waters, increasing temperatures, reduced food densities, and crowding”. This stress, or simply a lack of adequate food, can increase the likelihood of cannabalism.
Why are spadefoot toads different from other species?
They differ from true toads because they have vertical pupils and no parotoid gland. The American spadefoot toads are terrestrial when not underground. They are dully colored, usually a grey or dull green or brown, to aid in camouflage in their arid habitats.
How big are spadefoot toads?
Appearance. Similar to other burrowing frogs, American spadefoot toads are about 2-3 inches in length with round, stocky bodies and eyes that bulge from their heads. The name “spadefoot” is derived from the keratinous bone in its hind legs that allow it to burrow within soil.
What is the shape of a spadefoot toad?
The American spadefoot toads are of typical shape to most fossorial (or burrowing) frogs. They are round, with short legs and protruding eyes. As suggested by their name, these frogs have hard, keratinous protrusions present on their feet, which help them to dig.
Where do spadefoot toads live?
The New Mexico spadefoot toad ( Spea multiplicata) is a species of American spadefoot toad found in the southwestern United States and Mexico. Like other species of spadefoot toad, they get their name from a distinctive spade -like projections on their hind legs which enable them to dig in sandy soils.
How big do spadefoot toads get?
The New Mexico spadefoot toad grows from 1.5 to 2.5 inches in length, and has a round body, with relatively short legs. They are green, to grey, to brown, usually reflecting the soil color of their native habitat, often with black and orange colored speckling on their back, and a white underside. They have large eyes, with vertical pupils .
What is the behavior of a spadefoot toad?
Behavior. Like all species of spadefoot toad, the New Mexico spadefoot toad is nocturnal and secretive. If handled, these frogs might emit a peanutlike odor, which can cause tearing and nasal discharge if in close contact with the face. Spending most of its time buried in the ground, the spadefoot emerges during periods ...
When was the spadefoot toad designated as the official state amphibian of New Mexico?
The New Mexico spadefoot toad was designated as the official State Amphibian of New Mexico in 2003.
Is the New Mexico Spadefoot Toad a subspecies?
The species was once classified as a subspecies of the western spadefoot toad, Spea hammondii, but distinctive morphological characteristics led researchers to reclassify it as its own species. The New Mexico spadefoot toad is also known to hybridize with the Plains spadefoot toad, Spea bombifrons in the areas where their ranges overlap, making distinguishing the species from each other difficult.
