Little Frog

This little froglet is one of four mission golden-eye tree frog babies that hatched in the Emerson Children’s Zoo in early February this year. Mission golden-eye tree frogs ( Trachycephalus resinifictrix) are an arboreal species of frog native to the Amazon rainforest of South America. As adults they can grow to be about 4 inches, although this little one is about the size of your pinky nail at the moment. These frogs are very fast developers.After the eggs are laid, they usually hatch within 24 to 48 hours. After hatching, the tadpoles can take 30 to 60 days to morph into froglets. They usually start venturing out of water as soon as they grow front legs, and shortly after they will absorb their tail and complete metamorphosis into a froglet. Once the tail is absorbed, the little frogs will need to eat and begin hunting for any tiny insects they can catch. They develop a very pretty  bluish-grey color with black markings and a bright teal color on the inside of their mouth. We at the Children’s Zoo have really enjoyed watching the transformation of these little frogs and look forward to watching them grow into adults. #BringTheStlZooToYou

Slurping Slurry

#KeeperPerspective Check out one of our Emerson Children’s Zoo echidnas enjoying their slurry. They use their long beaks and long tongues to lap up their diet. #BringTheStlZooToYou

A Huge Snack

#KeeperPerspective Have you ever seen a millipede snacking on an orange? Emerson Children’s Zoo keepers captured this great video of one of our millipedes enjoying a huge snack. Well, huge for them! #BringTheStlZooToYou
