The Rohon-Beard cells of an urodelan Amphibian (Triturus cristatus) show their typical aspect and their highest number in the first larval stage. In the trunk region these neurons begin to degenerate at early larval stages and disappear a month before the metamorphosis. In the tail region, on the contrary, these neurons maintain the same number and morphological aspects till the oldest larval stages. Most of them degenerate in the last larval month. The Rohon-Beard cells of urodelan Amphibians progressively rarefy backwards and are quite lacking at the metamorphosis. The involutive features of these neurons are described.
