Colostethus larvae in different stages of development

The Granular Glass frog | Cochranella granulosa is almost always sitting out, rather cooperatively in plain view The Costa Rica exhibit - can you spot the newly emerged Lemur froglet ? A close up of the last Lemur frog metamorph from the first batch of 12 larvae put on exhibit last January!  6 new tadpoles are now inhabiting the water feature at the front of the exhibit. Here is the Lemur froglet | Agalychnis lemur , moments out of the water. Black-legged poison frog | Phyllobates bicolor , surveying the feast of wingless fruit flies before it. One of the Green and Black Poison frogs | Dendrobates auratus posing for the camera. Although there are 5 of these on display in the Costa Rica exhibit, they are not always in view The Mimic Poison frog | Ranitomeya imitator from the Amazon Exhibit One of the salamanders in the Salamanders of Georgia exhibit. This Green salamander is probably the least reclusive of the ELEVEN salamanders residin...

A Rain frog ( Pristimantis gaigei ) — a rare appearance in the Panama exhibit. Although there are four of these frogs in exhibit, they prefer to hide in the shadows. All four species in view at once! From lower left Rain frog (P. gaigei) , Rocket frog ( Colostethus pratti ), Green spiny toad ( Incilius coniferus ) and Crowned tree frog ( Anotheca spinosa ) A clutch of Rain frog eggs in the frogPOD That same clutch of Rain frog eggs, much further along in development.  Rain frogs are direct developers and skip the tadpole stage Dante's fantastic image of a couple of developing Rain frog embryos still in the egg

Calling male Rocket frog | Colostethus pratti For at least the past few weeks, the Rocket frogs | Colostethus pratti have been putting on quite a show in our ' Frogs of Panama ' exhibit. Originally, we introduced 9 Rocket frogs in the display, and the have subsequently bred so many times, it is next to impossible to get an accurate count now. I saw multiple age classes of these frogs last weekend. They are already the smallest species in this exhibit, so the froglets are quite tiny. Multiple egg clutches can be seen in the exhibit as well, if you look closely. I typically see the eggs laid on horizontally oriented leaves. Often, these egg clutches are guarded by the male. Once the eggs hatch, he will transport them on his back to water so they can develop aquatically into froglets. This egg guarding and tadpole transportation behavior is common in frogs in the family dendrobatidae (Poison frogs). Though frogs of the genus Colostethus are technically Poison frogs, the...

Bufo conifera | Green spiny toads becoming less shy and perching in the center of the exhibit Colostethus pratti | Rocket frog eggs just below the perching Spiny toads The low pressure system moving through Atlanta this weekend seems to have inspired activity in our frog exhibits (and the conservatory too!)The 'Frogs of Panama' exhibit in particular offered many exciting behavior displays, and I was fortunate enough to get some pictures. Anotheca spinosa | Crowned tree frog . Their colors vary throughout the day, here are 2 extremes
