Question

How do amplexusory pads help frogs?

Answer 1

Amplexusory pads also known as nuptial pads or nuptial excrescence. These pads are the secondary structures, found in mature male frogs. Also found in the salamander. These are formed when the androgen hormones are triggered. This is a type of mucous gland.

Complete answer:
The amplexusory pads are developed in the male frogs. These are softly padded like structures present below the first finger of the forelimb. This structure only develops during the breeding season. The pads are functional for holding the female frog during the process of copulation. These are the accessory organs that are developed only during the reproductive process. The vocal sacs are present only in males and during the breeding season. They attract female frogs by producing a loud sound. A nuptial pad is developed at the base of the first finger of the male frog. The vocal sacs increase the pitch of the sound, while the nuptial pads help in holding the female during amplexus or copulation.

Note: The fertilization of frogs is external. Both the male and females release their gamete cells in the water and fertilization occurs in the water. They produce thousands of offspring in one mating. The eggs mature in females from summer till late spring season, until the mating season begins.
