The feet of the hind limbs have 5 toes.
The forelimbs of frogs are primarily designed to support the hind limbs during sitting and walking. The back limbs are the ones designed for jumping.
Cetaceans have only vestigial hind limbs.
They enable an animal's locomotion.
Cats have four legs, which are considered limbs. Their front limbs are commonly referred to as arms or forelegs, while their hind limbs are referred to as legs or hind legs.
Coqui frogs, like other anurans (frogs and toads), possess paired appendages, specifically two front limbs and two hind limbs. These limbs are adapted for various functions such as jumping, climbing, and swimming. The structure of their limbs is typical of amphibians, with four digits on the front limbs and five on the hind limbs.
The function is locomotion.
The hind limbs are much longer than the forelimbs, but forelimb to hind limb ratio is quite variable. Toads and toad-like anurans have relatively short hind limbs.
A Lion has four limbs (legs) two fore and two hind.
Frogs push off their back limbs to jump, which makes them more powerful
There is no answer for this question because it does not make any sense.
While alligators are often confused with crocodiles, they belong to two quite separate taxonomic families. Alligators differ from crocodiles principally in having wider and shorter heads, with more obtuse snouts; in having the fourth, enlarged tooth of the under jaw received, not into an external notch, but into a pit formed for it within the upper one; in lacking a jagged fringe which appears on the hind legs and feet of the crocodile; in having the toes of the hind feet webbed not more than half way to the tips; and an intolerance to salinity, alligators strongly preferring fresh water, while crocodiles can tolerate salt water due to specialized glands for filtering out salt. In general, crocodiles tend to be more dangerous to humans than alligators. As for appearance, one generally reliable rule is that alligators have U-shaped heads, while crocodiles are V-shaped. Crocodiles have a longer narrower snout, with eyes farther forward. Also, if one looks at an alligator and then a crocodile, one will notice a difference in their mouths: only the upper teeth are visible when an alligator's mouth is closed, while a crocodile's mouth will reveal both upper and lower teeth, as their fourth tooth sticks out from the lower jaw, rather than fitting neatly into the upper jaw. Crocodiles also tend to have green eyes, while alligators have brown ones. Another distinction can be drawn between the jaws of the two animals. Crocodiles' jaws are much more narrow and are used to tear and grip on prey. By contrast, alligators' jaws are meant to crush bones, and can deliver a bite force of up to 3000PSI (though some larger crocodiles can deliver a bite force of over 5000PSI)
