| Research Abstract |
To validate the sensory function of deep sea animals, we performed the behavior observation of deep sea crab Gandalfus yunohana in a tank and found this species showed the directivity to heat. We successfully obtained a gene encoding a G protein-coupled receptor from Gandalfus yunohana and found that a possible candidate of a homologous gene exists in Gandalfus yunohan. We also found the occurrence of TRP channels in Paralvinella by behavior observation. The present study reveals the occurrence of various chemical sensors in deep sea animals and suggests these sensors possibly function for the adaptation to deep sea environment.
