Killing Name Of An Extinct Sirenian Species
2014-04-03 12:34:02

Pensoft Publishers Sirenians, or sea cows, are a particular group of mammals that superficially resembles whales in having, amongst other features, a streamlined-body and horizontal tail fluke. Though belonging to the so-called marine mammals, such as whales and seals, sea cows are members of a group having a single origin that includes their closest living relatives, the proboscideans (or elephants in the broader sense). Today, sirenians are known by only four species, but their...

Massive Manatee Deaths In 2013 Attributed To Red Tide Algae
2013-10-31 15:40:37

Michael Harper for redOrbit.com - Your Universe Online According to the Florida Fish and Wildlife Research Institute in St. Petersburg, the number of manatee deaths in 2013 has already reached a record high of 769 fatalities and there are still two months left to go in the year. These deaths account for about 15 percent of the total population and specialists expect the number to go even higher before the year is out. Motor boats, long the greatest mortal enemy of manatees, aren’t to...

Warm Springs Offer Better Protection Than Other Winter Refuges For Florida Manatees
2013-03-21 12:06:47

Public Library of Science During the winter, manatees in Florida rely on warm-water refuges in the southern peninsula, and consistently return to one more specific areas. This new study assessed the proportion of manatees that use natural springs, power plant discharge areas, and passive 'thermal basins' that trap warm water for a week or more. They found that nearly half of all animals they counted sought out power plant outfalls for warmth, while approximately 17% chose warm springs. In...

Red Tide Killing Record Number Of Manatees In Florida
2013-03-11 10:44:02

Brett Smith for redOrbit.com - Your Universe Online A red algae bloom, also known as Red Tide, is currently killing a record number of manatees living off the coast of Florida. Last week, the Florida Fish and Wildlife Conservation Commission (FWC) found an average of 10 dead manatees a day and some observers said the phenomenon doesn´t appear to be receding. A toxin produced by the red algae affects the nervous system of the manatees causing them to drown. "This is probably...

An article recently published in the Journal of Mammalogy, Volume 94 Issue 6 focuses on the struggling Florida manatee population and analyzes the factors pertaining to their decline. (PRWEB) January 29, 2013 Journal of Mammalogy — There is a better than 49 percent probability that the Florida manatee population will fall below 500 individual animals in the next 100 years, according to one analysis. One of the factors that can drive population decline is a lack of genetic diversity....

New fossil reveals history of last-living marine mammals to eat only aquatic plants A new fossil discovered in Tunisia represents the oldest known ancestor of modern-day sea cows, supporting the African origins of these marine mammals. The find is described in research published January 16 in the open access journal PLOS ONE by Julien Benoit and colleagues from the University of Science and Technology in Montpellier, France. Some fossils of sea cow ancestors have been found in Jamaica,...

Health Of Marine Ecosystems Associated With Health Of Manatees

April Flowers for redOrbit.com - Your Universe Online A team of scientists, led by George Mason University, have conducted a long-term study of manatees which may be a benchmark in determining health threats to marine mammals. The study, which ran over ten years in Belize, examined the behavioral ecology, life history and health of manatees in an area relatively undisturbed by humans. “Manatees are the proverbial ℠canaries in the mineshaft,´ as they serve as indicators...

The Amazonian manatee (Trichechus inunguis) is a species that can be found in the Amazon Basin, in a range that extends through Peru, Brazil, Ecuador, Colombia, Guyana, and Venezuela. It resides in freshwater habitats within these areas. This species is thought to reach a body length of 9.2 feet and females can weigh between 790 and 1,200 pounds, typically growing larger than males. It is grey in color, but can appear to be brown, and it has thick, wrinkled skin that holds little hair. Hair...

The African manatee (Trichechus senegalensis) is thought to be similar to the West Indian manatee. Its other common names include the seacow and the West African manatee. It is native to Africa, specifically Senegal to Angola and West Africa. Its range also includes Mali, the Democratic Republic of the Congo, and Ghana, among other regions. They can live in many water habitats including freshwater, oceans, brackish water, and lagoons. However, they will not live anywhere with a temperature...

The West Indian Manatee, Trichechus manatus, is the largest surviving member of the aquatic mammal order Sirenia. It is found along the coastal waters of the West Indies, generally in shallow areas. However, it is known to withstand large changes in water salinity, and so have also been found in shallow rivers and estuaries. These animals are limited to the tropics and subtropics due to an extremely low metabolic rate and lack of thick insulating body fat. Although in the summer they can be...
