Hi Snookn-
Cool salamanders indeed, but those animals are actually Siren lacertina and not Siren intermedia. Once you get south of the Green Swamp and northern Kissimmee Prairie, the adult S. lacertina have those large, irregular black spots under the gold and green striations, unlike the ones further north that tend to lose the spots once they reach 4 or 5 inches. It'll be interesting to see how many different species come out of this genus when it is all said and done...if it ever gets done.
Later, KW
