The snout of an African dwarf frog is pointed.
These frogs have tiny black claws on their hind legs, which caused one of their discoverers, Oskar Boettger, to originally call them African dwarf clawed frogs, [5] but they quickly lose these black tips in the sharp pebble environments and are more commonly called African dwarf frogs today. African Dwarf Frogs can swim up to 4 miles per hour ...
The temnospondyl Eryops had sturdy limbs to support its body on land Red-eyed tree frog (Agalychnis callidryas) with limbs and feet specialised for climbing Japanese giant salamander (Andrias japonicus), a primitive salamander The bright colours of the common reed frog (Hyperolius viridiflavus) are typical of a toxic species Wallace's flying frog (Rhacophorus nigropalmatus) can parachute to ...
The fish's hyomandibula bone in the hyoid region behind the gills diminished in size and became the stapes of the amphibian ear, an adaptation necessary for hearing on dry land. [23] An affinity between the amphibians and the teleost fish is the multi-folded structure of the teeth and the paired supra-occipital bones at the back of the head ...
An Asian elephant has smaller ears than an African elephant and a more uniquely shaped head. ... While neither animal is small by any means, African elephants are much bigger in every way when ...
An adult salamander generally resembles a small lizard, having a basal tetrapod body form with a cylindrical trunk, four limbs, and a long tail. Except in the family Salamandridae, the head, body, and tail have a number of vertical depressions in the surface which run from the mid-dorsal region to the ventral area and are known as costal ...
The upper part of the lips has a small notch on the distal side, while the lower lip are tall and lack inner lobes. The mandibular molar and palp may be absent or only present in vestigial forms. On the maxilla, the inner plates are setose and well-developed while the palp is often reduced and consists of only a single segment.
Caecilians have small or absent eyes, with only a single known class of photoreceptors, and their vision is limited to dark-light perception. [17] [18] Unlike other modern amphibians (frogs and salamanders) the skull is compact and solid, with few large openings between plate-like cranial bones. The snout is pointed and bullet-shaped, used to ...
