How does frog sex occur?

Frog Sex usually involves the male grabbing the female in a position called amplexus (pictured).

Many male frogs may develop a hard patch of skin on the back of their thumb; this ‘nuptial pad’ is presumed to aid in his grip on the female during this position.

The female frog is generally larger than the male, sometimes substantially so.

This enables her to support him during mating, especially if she is swimming or climbing.

As she releases the eggs, he fertilizes them externally.
