Question

Do all Boy frogs have a black substance on the inside of there front legs?

Answer 1

HEY BRO IT IS NOT BOY IT IS Male

When male frogs call, their throat region usually expands as their vocal sac fills with air, amplifying their call. Because of this, when not calling, males tend to have obviously thin, baggy skin on their throat. This skin is also usually a different colour to their belly (often yellow or black).

Answer 2

Explanation:

• A frog is any member of a diverse and largely carnivorous group of short-bodied, tailless amphibians composing the order Anura (literally without tail in Ancient Greek). The oldest fossil "proto-frog" appeared in the early Triassic of Madagascar, but molecular clock dating suggests their origins may extend further back to the Permian, 265 million years ago. Frogs are widely distributed, ranging from the tropics to subarctic regions, but the greatest concentration of species diversity is in tropical rainforests. There are over 6,300 recorded species, accounting for around 88% of extant amphibian species. They are also one of the five most diverse vertebrate orders. Warty frog species tend to be called toads, but the distinction between frogs and toads is informal, not from taxonomy or evolutionary history.
