"Filter-feeding dinosaur sieved its food." Filter feeders can play an important role in clarifying water, and are therefore considered ecosystem engineers. When their mouths take in a gulp of water, the water is filtered out, while the krill is trapped by special postcanine teeth that have developed on both their upper and lower jaws. Currently, the spotted wobbegong is listed as a species of least concern by the IUCN. Why do they do it?

The Basking Sharks' diet consists almost entirely of a single genus of copepod (Calanus), with a smattering of fish eggs and arrow-worms; this prey specificity suggests While the basking sharks mouth is about 17 percent of its entire body length, the megamouths is roughly 28 percent of its body length. This may have been the first free-swimming animal to filter feed. The Greenland shark is found in the North Atlantic. Filter feeders engage in one of the four major types of feeding, the others being deposit feeding (eating particles in soil), fluid feeding (as in spiders and hummingbirds), and bulk feeding (as in humans and most other animals).

How do leopards kill animals larger than they are? And to feed like whale sharkswith a sharp inhale that sucks in water in the immediate area requires stiff jaw cartilage to quickly open the mouth.
