Conchocele bisecta is an extremely large thyasirid very widely distributed in the northern Pacific Ocean, ranging from East China Sea to Russia to Oregon, USA. It is a chemosymbiotic bivalve hosting both methane and sulfur oxidising endosymbionts in a much enlarged gill, and relies on these for energy.

with "bisecta" likely referring to its distinct posterior ridge or "two-part" appearance. The genus name, Conchocele, is Latin-derived from "concha" (shell) and Greek "keleh," meaning to divide or split, which again alludes to a divided or notched aspect of the shell.
