Chytrid fungus has been plaguing amphibians globally resulting in a number of amphibian extinctions. Researchers are currently using non-invasive imaging technology to better understand how a specific species of tree frogs in Central America are proving resilience to this fungus. Scientist are attributing tree frog's ability to withstand the deadly fungus to their unusual skin which allows the frogs to bask in the hot sunlight boosting their temperatures adequately enough to kill off the fungus. While typically a frog's long exposure to sunlight would dry out its skin, this species of tree frogs in Costa Rica thrive under the high temperature conditions. Scientists believe these tree frogs are able to thrive under these harsh conditions, which normally negatively affect frogs because of their skins ability to reflect the sunlight, regulating their core temperature, yet maintaining enough heat to kill off the chytrid fungus. The antimicrobial skin peptides in the skin of "Agalychnis lemur" have shown to be a strong preventative measure for chytrid fungus, in particular Batrachochytrium dendrobatidis.
