8 weirdest frogs, from ultrasonic screamers to the bizarrely hairy

Turtle frog

The turtle frog, or Myobatrachus gouldii, is the amphibian counterpart of a mole and is undoubtedly the strangest of all frogs. Only found in Australia's arid southwest, it burrows through sandy soil using its strong forelimbs to find termites.

Trichobatrachus robustus

A furry, hairy frog? And stubby, feline claws? Africa's hairy frog, Trichobatrachus robustus, is undoubtedly stranger than fiction, even though either explanation may seem unlikely.During the mating season, this 11cm-long frog gets hairy, with the male developing a thick fringe over his thighs and flanks that resembles bristles.

Glassfrog

More than any other animal, tropical American glassfrogs have most likely developed an invisibility cloak. Furthermore, recent studies show the extent to which these amazing amphibians will go in order to improve the illusion.

Common coquí

Are frogs louder than Common Coquí? A typical characteristic of frogs is their croaking, which they use to mark their territory and draw potential mates. However, the frog's croak volume is not much affected by its size.

Southern cricket frog

A frog's skeleton is modified in several ways to enable it to jump extremely well; among frogs, the southern cricket frog is arguably the greatest. Although a frog's muscles propel the leap, they are insufficient to account for the creature's capacity for vertical jumping.

Paedophryne amauensis

Paedophryne amauensis is one of the smallest vertebrates on Earth, measuring only 7.7 mm in length. The micro-amphibian, which was found in 2009 following a meticulous study of Papua New Guinea's woods, is a terrestrial species that does not have a tadpole stage.

Surinam toad

a South American frog whose offspring emerge from the rear of the mother. If you can see it at all, the Surinam toad—so named because of its ambiguous name—is the most unlike a frog you will ever see.

Clay robber frog

In Amazonian Brazil, the clay robber frog is not as silent as it looks. According to reports, it screams loudly to ward off would-be predators, but because it does so in ultrasonography, humans are unable to hear it.
