To catch prey, they widely open their lower jaw almost 90 swim through a swarm gulping, while lowering their tongue so that the head's ventral grooves expand and vastly increase the amount of water taken in. VISION The structure of shark eyes is remarkably similarly to our own. Basking sharks collect plankton by expanding their mouth wide open and swimming through the water at a continuous pace, a method called ram feeding, while whale sharks primarily capture food in bursts by quickly expanding their jaws and inhaling amid a cloud of plankton. Of course, there must be a critical concentration of food particles in the water, or the filter feeder will starve. an animal that eats both plants and animals, This insectivore has a long tongue and nose, which it uses to lick up ants, An animal that finds already dead animals to eat, This omnivore eats berries in summer and salmon in the fall, Many filter feeders in the ocean eat this, A desert scavenger that can often be seen flying above dead animals, Animals get this from eating other animals, An animal that is hunted by other animals, This insect spreads parasites when it drinks the blood of animals.
