So I live in Northern Mississippi and we never see many salamanders or newts but I discovered a little stream flowing through the woods and there were some salamanders in it but from what I observed the smallest ones (2-3 cm) did not have any gills but most definitely salamanders and the largest ones I saw (2 inches) were a yellowish brown with gills I plan to go back and get photos but I don't want to hurt the animals so it may be a little difficult I will keep updating this thread for help but if anyone knows a species of salamander that as a baby has no gills but progressively grows them I would appreciate the response and of course they could be two different species of salamander still unclear though
