Boreopterids are thought to have relied on a kind of rudimentary filter feeding, using their long, slender teeth to trap small fish, though probably lacking the pumping mechanism of Pterodaustro. Kennedy, Jennifer. During the slight delay between closing the mouth and opening the gill flaps, plankton is trapped against the dermal denticles which line its gill plates and pharynx. Instead of teeth, these whales have baleen, or plates made out of keratin, the same material that makes up our hair and fingernails. Most forage fish are filter feeders. Some animals that do this are clams, krill, sponges, baleen whales and many fish such as sharks. . 72.
