Lesser Siren

Image and video hosting by TinyPic

Yesterday our class went on a field trip to the Francis Marion National Forest. We found several frogs (mainly Southern cricket and one Pig frog) and a Lesser siren (Siren intermedia). It's hard to tell the Greater siren from the Lesser siren but we determined it was a Lesser siren because of it's length. This little guy had two tiny front legs and no hind legs. The Lesser siren had external gills and lacked eyelids which are characteristics of paedomorphism We found him in a trap set by the professor in shallow water. Sorry the picture is not better, it was taken from my phone.
