Question

Name the characteristic type of vertebrate found in reptiles, birds and mammals.

Answer 1

They are warm-blooded vertebrates more related to reptiles than to mammals. They have a four-chambered heart (as do mammals), forelimbs modified into wings (a trait shared with bats), a hard-shelled egg, and keen vision. ... In a manner similar to their relatively close relatives the reptiles, birds lay shelled eggs.

Answer 2

Characteristic type of vertebrate found in reptiles, birds and mammals:

• The integumentary system of reptiles, most fish and some mammals and such similar structures are The 'type of scale' found over the body of 'Labeo rohita ctenoid' or 'dermal'.
• The similar structures are found in butterflies and moths. They form the 'dermal or epidermal layer' or structure. The 'cycloid scales' are most often found on carps and similar fishes are common to higher bony fishes. The morphology determines the types of species it belongs to.
• The bird skeleton is not heavy, it’s lightweight, and it has enough withstanding power and stress handling power. The kind of bone arrangement and hallow bones makes the skeleton lighter to fly and allows the more oxygen to absorb from the surrounding atmosphere for more energetic and smooth flow.
