They are a newt Chris.They are the juvenile stage of the eastern red spotted newt.The newts after going through a larval stage become terrestrial for two to three years and this is the stage you are seeing.At about three years of age they loose the orange coloration but keep the spots and become olive green,grow gills and enter the water never to leave.They used to be quite common in pet stores,may still be?They are quite cool.I have been in north jersey during a series of showers once,it was stokes state forest amd there were hundreds of them walking all over the forest floor.I wish they stayed that way,they are so beautiful,not ugly when they turn green but not as wow as when their orange.
