__Zoologists__ There are many animals that live in the marine. There are polar bears, sea lions, whales,clownfish and so many more. Some of the animals however are in great danger. We can help them by recyling. There are over 5,000 deaths of animals in the ocean each day. But at least 3,000 animals are born each day.



"//**Phytoplankton:** These are the single-celled marine plants that live on the sunlit upper layers of the ocean, the "euphotic zone". Phytoplankton include dinoflagellates, coccolithophores and diatoms. The phytoplankton are known as the primary producers of food because they use solar energy to convert carbon dioxide and the other nutrients into carbohydrates that are used by the marine creatures. Ninety-five percent of the primary food is derived from the phytoplankton." "**Zooplankton:** The small floating animals known as zooplankton eat the phytoplankton. Shrimp, copepods, jellyfish, mollusc are some of the examples of zooplankton. The larger zooplankton eat the smaller zooplankton." "**Small Bait Fish:** Examples of small bait fishes include sardines, crabs, lobsters and herrings. These fishes eat zooplankton and the larger fishes of the ocean in turn eat them. " "**Large Fish:** Shark, sword fish, tuna and octopus are examples of large fishes. The larger fishes feed on smaller fishes

"**Predators:** The predators of the ocean include whales, killer whales// //and so on. The predators form the fourth layer of the ocean food chain. The predators during their feeding season feed not only on the larger fishes, but also on the members of their species or groups. //Cephalopods are animals like squid and octopus."Cephalopod" means "headfoot" in Greek, because cephalopods don't really have bodies, just heads and feet.
