"Thus, snakes detect infrared signals through a mechanism involving radiant heating of the pitorgan, rather than photochemical transduction," says the study.
“因此，蛇类通过陷窝器进行辐射供热的结构来探测红外信号，而不是靠光化学转换。”研究显示。

Rather, the so-called TRP1 "wasabi receptor" in the tissues directly feels the heat inside the pitorgan, a sensation like your skin feeling heat from a warm object.
