Some species live in highly specialized environments. Poison dart frogs hop through the tropical rainforests of Central and South America, while northern leopard frogs ( Lithobates pipiens) inhabit much of North America's marshlands, brushlands and other habitats, including farmland and golf courses, according to the University of Michigan's BioKids website. They need to be around water sources to reproduce, but their habitats are extremely varied otherwise.

The researchers noted at the time that the frogs could represent the tip of a giant iceberg of unknown amphibians just in Mexico, Live Science previously reported. For example, researchers described six new species from Mexico in April 2022, and each can fit comfortably on a thumbnail. While there are thousands of known frog species, there are likely many more that scientists haven't found yet. "This change in brightness makes the frogs a closer match to their immediate surroundings, which are predominantly made up of green leaves." "The frogs are always green but appear to brighten and darken depending on the background," lead author James Barnett, a behavioral ecologist at McMaster University in Ontario, said in a statement (opens in new tab) at the time. A 2020 study published in the journal Proceedings of the National Academy of Sciences (opens in new tab) (PNAS) found that these frogs aren't truly transparent, but their camouflage is flexible. They've evolved for predators to look straight through them. Glass frogs have translucent green skin that makes their internal organs, and even beating hearts, visible to the human eye.

The world's smallest known frog is a tiny species called Paedophryne amauensis from Papua New Guinea. ![]() Goliath frogs appear to use their great size to shift rocks weighing more than 4 pounds (2 kg) to build " nursery ponds" that they clean and guard, Live Science previously reported. The largest frogs are Goliath frogs ( Conraua goliath) from Cameroon and Equatorial Guinea they can grow to be more than 1.1 feet (34 centimeters) long and weigh 7.3 pounds (3.3 kilograms), according to a 2019 study published in the Journal of Natural History (opens in new tab). ![]() ![]() Frogs come in a variety of shapes, colors and sizes. ![]()
