Coral Reefs need to be preserved for many reasons. In this paper I will discuss a few of them. First of all‚ they houses a collection of diverse organisms‚ and contribute fisheries which provide food items such as fish‚ crustaceans‚ and mollusks. Furthermore‚ coral skeletons are being used as bone substitutes in reconstructive bone surgery and may be able to provide important medicine‚ including anti-cancer drugs and a compound that blocks ultra-violet rays‚ they even help reduce global warming

The viperfish is found at depths of 500-2500 meters during the day in the part of the ocean sometimes called the "twilight zone‚" because very little light penetrates to that depth. When it goes in search of the crustaceans and small fish that are its main sources of food at night; it rises as close as to the surface as 80 meters where food is more plentiful. The Viperfish occurs in tropical and temperate marine waters world-wide. In Australia‚ specimens

Cuttlefish are able to catch fairly large pray such as fish‚ crustaceans like crabs‚ shrimp‚ and prawns which are a marine animal that resembles a large shrimp.

whale travels in pods making trips of twelve thousand miles going from Mexico to Alaska and back. The grey whales feeding manner is different than most whales as they turn on their sides picking up sediment from the floor of the ocean taking in crustaceans and bottom dwelling creatures. They filter out the food by separating the water and the sediment through its sleeve like baleen. The change of the climate has created a concern for the grey whales. Rise in the sea temperature has made the arctic

deep ocean The oceans cover 75% of the world’s surface and contain 97% of its water; 90% of the seas lie beyond the shallow continental margins‚ and most are deeper than 2km. With the advent of modern science we have been able to discover what some of the deep ocean is like but there is still a vast area that remains unexplored. One thing we do know is that life at these depths is dominated by animals‚ not plants

Mollusks Page 1 Mollusks comprise a group of soft-bodied animals that includes snails‚ clams‚ and sea slugs. The most common characteristic of most mollusks is their shell. One of the largest groups‚ the snails‚ is renowned for their shells. Snails are univalves‚ which means they have one shell. And it is this shell that for many people is the epitome of the ocean. There is perhaps no other ocean treasure that displays more diversity and beauty than the shell. Conchology‚ the study and collection
