The ruff of skin covering the reptiles’ heads and neck is the most distinctive feature of these creatures. Long cartilage spines attach to the jaw bones and support the neck frill’s shape.
In contrast to most other species of amphibians, axolotls do not go through metamorphosis to reach adulthood. Adults remain underwater and gilled rather than attempting to leave the water.
They get what looks like hair on their thighs and sides when they’re reproducing. The frog’s dermal papillae are not hairs but dermal papillae with arteries that assist the frog in absorbing more oxygen.
An endangered species of artiodactyl mammals. Okapis have striped markings similar to those found on zebras, but they are more closely related to giraffes.
