Frogs invest in cognitive capacity to avoid predators—up until there are too many hungry snakes around for the evolutionary strategy to pay off.

The inner ears of these miniature Brazilian frogs are too small to provide good balance while jumping.

A new chemical treatment allowed African clawed frogs, which normally don’t regenerate limbs, to regrow functional hind legs following amputation.

Across the tree of life, animals use sound and other vibrations to glean valuable sensory information about their environments even before they are born.

Recent findings buck the traditional idea that embryos are passive agents and instead suggest that by tuning into vibrations, organisms can better prepare to enter the outside world.

Watch and listen to reptiles, amphibians, insects, and birds respond to sound from inside their eggs.

His career was dedicated to understanding and protecting frog populations.

Understanding biology’s software—the rules that enable great plasticity in how cell collectives generate reliable anatomies—is key to advancing tissue engineering and regenerative medicine.

A study of the animals using blue light reveals what humans are not able to see with the naked eye.

Unable to break through the water’s surface, tadpoles have a unique workaround for breathing air.

They’ve survived volcanic eruptions, but one Caribbean island’s mountain chicken frogs might need help from scientists to escape the lethal chytrid fungus.

Scientists hope to breed the species in captivity because their habitat has nearly disappeared.

A survey reveals the disease has decimated populations in Central and South America and tropical Australia and contributed to the extinction of 90 species.

Amputation of one limb triggers a rapid electric response that reflects the injury in the opposite one, researchers find.

A newly described amphibian has such a small range in southern Brazil that it’s already critically endangered.

A once critically endangered species of leaf frog has made a comeback. 

A cornucopia of toxins in the animal kingdom could provide inspiration for novel painkillers, but so far, effective drugs have proven elusive.
 

The phenomenon is one of the few examples of eavesdropping across the vertebrate/invertebrate barrier.

The polka dot tree frog (Hypsiboas punctatus) glows under a blacklight, due to the presence of three fluorescent molecules in its lymph tissue and skin.
