Blue Whales The Blue whale is the largest creature of the sea, in fact, it is the largest creature known to man. Contrary to what most people think, even though Blue whales live in the sea, they are mammals. They breathe air, have their babies born alive and can live anywhere from 30 to 70 years. The Blue whale is a baleen whale, and instead of having teeth, Blue whales have around 300-400 baleen plates in their mouths. They fall under the category of the rorquals, which are the largest of the baleen family.

The manatees consequently eat up the vegetation, which frees u... ... middle of paper ... ...s that they can travel up to fifty kilometers a day, and go back to a designated location every season. Further developments in manatee research will help in preventing the accidental death of many of these animals. The research that scientists have learned from the transmitters will help in regulating boat speeds in certain areas to avoid the propeller deaths of many manatees, thus decreasing the death toll.
One of the most distinctive features of orcas is the tall, wide dorsal fin located on its back. In females, the dorsal fin can grow to about 2 feet high. It is falcate (hooked or curved).

Many believe the legends and folklore of the mermaid may have originated with these creatures. When you get a close up view of these slow, enormous, sea cows this may produce hilarity. The manatee can measure up to thirteen feet in length and weigh as much as 1300 pounds. They have a brownish, grey exterior, with whiskers on their snout.
