This Frog Changes Colors to Impress Females

The Indian bullfrog may not look like much until it’s time to impress the ladies.

When this frog is ready to mate, he changes color from a dull olive green (below) to a brilliant shade of yellow. As if that weren’t fancy enough, his vocal sacs turn bright blue to perfectly contrast his new skin tone.

The brighter his colors, the better he looks to his potential mates.

The Indian bullfrog is a large species of frog, attaining a length of up to 6.5 inches. While native to countries throughout Asia and India, these frogs have recently been introduced to Madagascar where they have taken over as an invasive species.


Regardless of where you find them, you’ll spot them throughout wetlands and aquatic habitats generally hiding among the vegetation. When frightened, these acrobatic frogs are known to jump on water as if they were on land! However, we don’t suggest harassing them to see it.

These brilliantly colored frogs dine on insects, various invertebrates, small rodents, birds, and even snakes.

Unfortunately for them, many people in Asia have a taste for their legs. In the 1990’s, Thailand began farming the species to meet the needs of the market. We prefer seeing them enjoying their native habitat, though.
