One species of these animals often has its eyes infected by the copepod Ommatokoita (-5[1])elongata, which might (-5[1])attract prey through bioluminescence. (-5[2])That species of these animals contains toxic amounts of trimethylamine (10[2])N-oxide and urea, (10[1])which allows it to live at great depths. (10[1]-5[1])This is the largest group of animals whose intestines contain a spiral valve to increase surface area and a specialized liver full of squalene to maintain buoyancy. The cephalofoil shape of one of these animals’ heads is thought to enhance electroreception. A slow swimming “sleeper” one of these animals is named after Greenland.
