Studies on molecular basis of snake olfaction and the speciation between two sympatric sibling species of sea snakes.

分析了全水栖蛇、两栖蛇和陆生蛇的嗅觉受体(OR)基因谱带。因此，已经证实，水生适应不仅会导致哺乳动物的OR基因数量减少，也会导致蛇的OR基因数量减少。然而，与海洋哺乳动物不同的是，海蛇仍然拥有发育良好的犁鼻器。此外，还比较了两个同域近缘海蛇物种马尾蛇和额蛇鱼的OR基因谱带，但它们之间没有显著差异。

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.
