Question

How is a frog's coloration similar to that of a fish?

Answer 1

Three types of pigment cells, called chromatophores, work together to make a frog green.

The chromatophores stack on top of each other. Melanophores make up the bottom layer. They contain melanin, a pigment that appears dark brown or black. Melanin also tints human skin.

Answer 2

Explanation:

For example, melanin increases with ultraviolet radiation (UV) and temperature in frogs and fish. However, little is known about how environmental variables influence the amount of coloration on organs among amphibian species over a large spatial extent. ... Coloration in all organs was correlated with the phylogeny.
