Predators must have some advantage over their prey, the animals they eat, in order to capture them. Whales were at the top of their food chain until man started to hunt and kill them.ДЄn animal that catches another animal and eats it is called a predator. For example, sharks, lions, human beings, and elephants are said to be at the top of their food chains. A species is at the top of its food chain if there are no animals which kill and eat it regularly. The small fish are eaten by larger fish, and those are eaten by even larger fish and so on up the food chain. The zooplankton are then eaten by small fish and some whales. Phytoplankton are eaten by small fish and by zooplankton, a class of plankton-eating microscopic animals that includes single-celled animals, larvae of larger animals, and tiny crustaceans. The term вЂњplanktonвЂќ comes from the Greek word вЂњplanktos,вЂќ which means вЂњdrifting.вЂќ Phytoplankton range from microscopic organisms to sea weed. In the ocean the base of the food chain is phytoplankton, or algae, plants that live near the surface of the water (to get maximum sun). When the plant-eating animal is killed and eaten by another animal, it is said that the animal who is eating is higher on the food chain than the animal being eaten. The animals that eat the plants are one link up the food chain. Plants are always the base of the food chain. The food chain describes the fact that each living creature survives by feeding on plants or other animals. Development also harms turtles by encroaching upon their beaches and confusing the innate directional signals of hatchlings. Their population has declined as they drown in fishing nets and as land animals, such as raccoons, cats and dogs, prey upon their eggs. Loggerhead turtles are a threatened species. Loggerheads migrate the breadth of the Pacific Ocean, often traveling along ocean currents. When they are resting, they can remain underwater for as long as two hours. They breath air and when active must swim to the surface after a few minutes. Loggerheads can see well underwater and are believed to have an acute sense of smell. They also eat invertebrates and some types of sea grasses. They eat mollusks, such as shrimp, horseshoe crabs, blue crabs, clams, and mussels. Loggerheads have powerful jaws designed to crush shellfish. It has a heart-shaped reddish brown shell. The loggerhead is named for its disproportionately large head (when compared with other turtles), which may measure 9 inches wide (25 cm). Their major nesting beaches in the United States are in South Carolina, Georgia, and Florida. In the Atlantic, their range is from Newfoundland to Argentina, including the Gulf of Mexico, and Caribbean sea. They are, for example, the most common turtles in the Mediterranean, in the oceans around the U.S., and in the coastal ocean waters of Brazil etc. Loggerheads live in most of the tropical and temperate coastal waters around the globe. Biologists are not sure where juvenile turtles grow, but it is thought they inhabit floating islands of seaweed where they feed and grow to young adult size. After laying her eggs, the female turtle covers them with sand and leaves. Eggs are laid throughout the summer in shallow pits dug in open beaches. Loggerheads mate in late March through early June. Sightings of 5 foot long turtles weighing as high as 1000 pounds have been recorded. Loggerhead Sea Turtles - Usually about to 3 feet (1 m) in length and weighing 350 to 400 pounds (182 kg) loggerhead sea turtles (caretta caretta) reach maturity at between 16 and 40 years.

Clownfish live in the tropical parts of the Pacific and Indian Oceans or where warm, tropical waters are carried by currents, such as the east coast of Japan Divers have damaged many reefs looking for prime specimens. Eggs are laid in large batches, usually near and sometimes within the host anemone.Д¬lownfish are not eaten by man, but their bright colors make them popular for saltwater aquariums. Clownfish also eat the dead tentacles of their host anemone. Clownfish eat leftovers from fish consumed by anemone, planktonic crustaceans, and algae. Scientists believe that by dancing up against the tentacles for a time clownfish develop a protective mucous covering. In fact, most of the scientific literature refers to them as вЂњanemone fish.вЂќ Clownfish are not immune to the poison in the anemoneвЂ™s tentacles and at first appear to be stung by them. Clownfish are often sheltered by an anemone with whom they They are 2 вЂ“ 5 inches (5 вЂ“ 12.5 cm) long. Clownfish are small and often brightly colored. Their scientific name is amphiprion ocellaris. FICTION (SOAPS, DRAMAS, AND REALITY/SURVIVAL SHOW)Д¬lownfish - Nemo and Marlin belong to one of about 27 species of clownfish.
