One species of these animals often has its eyes infected by the copepod Ommatokoita elongata, which might attract prey through bioluminescence. That species of these animals contains toxic amounts of trimethylamine N-oxide and urea, (10[2])which allows it to live at great depths. (10[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. (-5[1])The cephalofoil shape of one of these animals’ heads is thought to (10[1])enhance (10[1])electroreception. (10[1]-5[1])A slow swimming (-5[1])“sleeper” one of these animals (-5[1])is named after Greenland. (10[1])For 10 points, name these predatory cartilaginous fish that have great white (10[1])and hammerhead varieties. (10[1])■END■ (10[2])
