The Blacked Eyed Tree Frog is the less popular cousin of the Red Eyed Tree Frog. Like the Red Eyed Tree Frog, they are nocturnal, spending the day hiding on leaves off trees. The frogs can be found in the pet trade but most of them are wild caught. Buying wild caught frogs is wrong in my opinion. The species epithet moreletii is in honor of french naturalist and illustrator Pierre Marie Arthur Morelet. Morelet didn’t study frogs, he was actually really interested in mollusks.

During the rainy season, the males of the species will start to call on elevated areas around pools, lakes, and streams. The female frog will select a mate and the two will embrace in amplexus. The female will lay her eggs on rocks and leaves over hanging water and the male will fertilize them. The female lays between 50 to 70 eggs. Once the tadpoles hatch in 5 to 10 days, they fall right into the water to finish their metamorphosis. This stage of the metamorphosis takes around 55 days.

While the International Union of the Conservation of Nature (IUCN) Red List only lists the Black Eyed Tree Frog as Least Conservation of becoming extinct, the species is in trouble. It was formerly listed as Critically Endangered in 2004 due to Chytrid Fungus wiping out populations in Mexico. It was predicted the fungus would eliminate populations in other countries. So far, the disease hasn’t done that. The habitat of the frogs are fragmented and are endangered due to habitat destruction for farms and cities.
