| Research Abstract |
Olfactory receptor(OR) gene repertoires in fully aquatic, amphibious and terrestrial snakes were analyzed. As a result, it has been confirmed that aquatic adaptation causes the reduction of the number of OR genes not only in the case of mammals, but also in the case of snakes. However, unlike marine mammals, sea snakes still possess well-developed vomeronasal organs. In addition, the OR gene repertoires between two sympatric sibling sea snake species, Laticauda colubrina and L. frontalis were compared, but there are no significant differences between them.
