The Yellow-eyed Leaf Frog

The Yellow-eyed Leaf Frog (Agalychnis annae) is an endangered species found only around San Jose, Costa Rica. It is part of the official captive breeding programme in the Vivarium Manchester Museum which aims ensure the species' survival. #WorldAnimalDay



These beautiful nocturnal frogs sleep during the day and are active at night. This species was once common in Costa Rica. However numbers have declined and now they are only found in a few places. 



These frogs grow to an adult size of up to 85mm and eat insects. They reproduce by laying their eggs on leaves overhanging water, and when the tadpoles hatch they drop into the water below to continue their development.



Our Vivarium team are doing fantastic work, not only for conservation of species, but also to increase awareness and education. Today we a celebrating #WorldAnimalDay which aims help make the world a fairer place for all animals. Find out more here:
