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