Why other cetaceans don’t eat sharks. ... What Do Mahi Mahi Fish Eat? Note: Cetaceans include all species of whale, dolphin and porpoise. In the food chain of salt water fish, the top predators are sharks. Additionally, many species of bottom feeder or foraging fish are filter feeders and play an important role in regulating the ocean's food chain and water quality. Organisms in a community are linked through what they eat and what eats them. The large predators that sit atop the marine food chain are a diverse group that includes finned (sharks, tuna, dolphins), feathered (pelicans, penguins), and flippered (seals, walruses) animals. Because that's what they eat sometimes, most animals eat other animals which eat other animals which eat plants, its called the food chain, we'll learn more about it later. A study in North Carolina showed that the loss of the great sharks increased the ray populations below them. Sharks’ control over species below them in the food chain indirectly affects the economy. These sharks keep populations of their prey in check, weeding out the weak and sick animals to keep the overall population healthy. The marine food chain is one amongst them. Filter feeding is the same method of feeding used by clams, krill, sponges, jellyfish, manta rays, whales and several other species of sharks. The food chain begins with the tiniest microorganisms who are the major producers of food in the ocean and are in turn, consumed by bigger lives, which are eventually preyed by the largest marine lives such as whales and sharks. While not all sharks are hunters (the largest, the whale shark, eats mainly zooplankton), many are voracious predators. Marine clam species live buried in sand or mud and they feed on plankton (both phytoplankton and zooplankton) by filter feeding. There are a number of reasons other species of cetcea do not eat sharks. As a result, the hungry rays ate all the bay scallops, forcing the fishery to close. Ecosystem of a Shoreline.

Colossal and giant squid are close to the top of the food chain, able to eat any sea animal they can catch. Giant and colossal squid are two of Earth's largest animals, their length exceeded only by the sperm whale. FOOD CHAIN It goes from energy from the sun Plankton Producer, Primary Producer, ocean sun fish secondary consumer, Small shark and large shark quantery consumer. In a typical marine food chain, dinoflagellates convert energy from sunlight into food through photosynthesis and store it in their tissues. Reaching 46 feet long, colossal squid are the largest known invertebrate. Many shark species are "apex predators," meaning they reside at the top of the food web. ... these sharp teeth and the fact that sharks do prey on sea animals are likely reasons that people’s fears rest so much on sharks, and less on the chance that a whale eats a person. A food chain is a single pathway connecting a producer with several levels of consumers.
