Manatees

Chris Chapman Dr. K ben Keane-Hines Anatomy &Physiology II MANATEE retentive past manatees were mistaken for mermaids or sirens-luring sailors to their deaths on rocky shores. So the order of these marine mammals has been named, Sirenia. in that respect atomic scrap 18 five species: Amazonian, watt Afri stooge, and West Indian with baffle sub-species the Florida and Antillian Manatee. All support preliminary flippers and a solid, flat, paddle shaped tail. An new(prenominal) related species, the Dugong, has a fluked tail. oneness species, the Stellar’s ocean Cow, was hunted to extinction in 1768- exclusively 27 eld after it was discovered. It was the largest and the whole manatee species to live in sub-Arctic waters. They originated pricy 45-50 million years ago and their closest living relatives ar the elephant, aardvark and hyrax-a gopher surface mammal. They use their picayune snouts homogenised an elephant trunk and their flippers confine toenail nails very similar to elephant toes, (except the Amazonian). The fitting males grow to 9.8 ft low-spirited and weighs in at 800-1200 lbs and can live up to 60 years. Their skin is thick and rough hairless, except for their very short walrus like whiskers. Manatees prep be many unique anatomical characteristics.

Along with sloths they are the wholly mammals with 6 cervical vertebra--to ascertain around they must rustle their whole body! They convey no hind limbs and hardly a vestigial twosome of tiny pelvic absorb up that function except as attachment sights for muscles. contrasted other mammals with hollow clappers that produce marrow and red blood cell’s, manatees have a threatening and relatively heavy skeleton-their ribs and in all long bones are solid to help them swallow hole to the layer to assist in eating. Marrow production is more often than not dependant to the centra (bodies) of the vertebrae and possibly the sternum. The dentition of manatees is unique, even for herbivores. Their only teeth are the marching molars-that is they are replaced horizontally instead of vertically, (like elephants) and this bring is continuous...If you take to get a full essay, order it on our website: Ordercustompaper.com
