Five of the six documented samples of a rare species of this animal, which has never been seen alive and has a spade-shaped tooth, have been found in (10[1])New Zealand. The nitrogen-rich (-5[1])flocculent feces of these animals contributes to their namesake “pump,” (10[1]-5[1])which moves nutrients in the opposite direction of the biological pump. (10[1])Some species of these animals cooperatively use “bubble (-5[1])nets” to feed. (10[6]-5[4])Nutrients (-5[1])can be supplied (-5[2])two thousand (-5[1])times (-5[1])faster than marine snow by ecosystems (10[1])composed of (10[1])these (10[1])animals’ (10[1])carcasses, (10[6]-5[1])which (10[2])are (10[1])named (10[2])for their (10[1])“falls.” (10[6])A toothless (10[3])variety of these animals (10[1])feeds by taking in (10[1])and then expelling water through (10[1])a keratinaceous plate (10[1])to filter krill and plankton. (10[1])For 10 points, name these large aquatic mammals (10[1])that include baleen and humpback (10[1])types. (10[1])■END■ (10[7])
