Question

why does frog has triangle head and webbed feet

Answer 1

Explanation:

these mutation were beneficial to many semiaquatic animal because the increase surface area from the webbing allowed from more swimming propulsion and swimming efficiency,especially in surface swimmers. the webbed foot also has enabled other novel behaviors like escape responses and mating behaviors

Answer 2

Answer:

The webbed foot is a specialized limb present in a variety of vertebrates that aids in locomotion. This adaptation is primarily found in semiaquatic species, and has convergently evolved many times across vertebrate taxa. It likely arose from mutations in developmental genes that normally cause tissue between the digits to apoptose. These mutations were beneficial to many semiaquatic animals because the increased surface area from the webbing allowed for more swimming propulsion and swimming efficiency, especially in surface swimmers.[2] The webbed foot also has enabled other novel behaviors like escape responses and mating behaviors. A webbed foot may also be called a paddle to contrast it from a more hydrofoil-like flipper.
