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...

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,...

These days, only four species of Sirenian, more commonly known as the seacow, manatee or dugong exist in a given world region. Smithsonian scientists, however, have been studying fossil records of the ancient mammals and have discovered evidence that this hasn´t always been the case. According to these fossil records, which date back 50 million years ago, multiple species of seacow once existed together. The research also suggests the environment these seacows resided within, as well as...

Italian scientists have discovered the bones of an extinct sea cow species that lived over 20 million years ago in a Philippines cave. Limestone rock above the waters of an underground river on the island of Palawan revealed several ribs and spine parts of the aquatic mammal, says expedition head Leonardo Piccini, a geologist from the University of Florence. The discovery of the extinct sea cow species was announced during a symposium at the Philippine presidential palace. Piccini says that...

Change view of water temperature during time when first modern mammals emergedWhat tales they tell of their former lives, these old bones of sirenians, relatives of today's dugongs and manatees.And now, geologists have found, they tell of the waters in which they swam.While researching the evolutionary ecology of ancient sirenians--commonly known as sea cows--scientist Mark Clementz and colleagues unexpectedly stumbled across data that could change the view of climate during the Eocene Epoch,...

The marine resources minister said Tuesday that Sierra Leone is mulling new laws to protect the West African manatee which is under threat from bushmeat hunters, fishermen and rice growers who see it as a pest. Soccoh Kabia opened a one-day workshop in the capital with an appeal "to end the massive hunting and killing of manatee in spite of national laws protecting and conserving" the manatee. "The purpose of the workshop is to ... develop a conservation law that will lead to the protection...

Two Belize Populations Offer Opportunity in a Desert of Genetic DiversityThe first genetic study to compare nuclear DNA of endangered Antillean manatees in Belize with Florida manatees confirmed their designation as separate subspecies. Belize's manatees, however, were found to have extremely low genetic diversity, raising questions about their long-term genetic viability.The Central American country of Belize hosts the largest known breeding population of Antillean manatees and is touted by...

Efforts to protect Manatees in Florida have not worked, possibly because the sea cows could be hard of hearing, a researcher says. The Sunshine State has created manatee safety zones and slow wake waterways designed to protect them, but the sea mammals repeatedly get in the paths of boats and are slashed by propellers. Florida Atlantic University researcher Edmund Gerstein has measured the hearing abilities of manatees for 17 years, trying to understand why manatees get in the way of boats,...

By Curtis Morgan, The Miami Herald Jun. 16--Florida's wildlife managers are contemplating a fresh approach to the difficult business of deciding whether the West Indian manatee and dozens of other critters are endangered or threatened: Let somebody else do it -- namely, the federal government. In a move aimed at quelling a decade of impassioned debate over the status of the manatee and, by extension, the state's entire controversial system for ranking imperiled species, the Florida...

Researchers from Oxford University and Stony Brook University have discovered an ancient water-dwelling mammal that had close ties to modern day elephants.The animal is similar to a tapir, a hoofed mammal that resembles a cross between a horse and a rhino."It has often been assumed that elephants have evolved from fully terrestrial ancestors and have always had this kind of a lifestyle," said DR. Erik Seiffert, co-author of the study published in Proceedings of the National Academy of...

Amazonian Manatee, Trichechus inunguis
2014-04-11 11:46:02

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...

African Manatee, Trichechus senegalensis
2012-06-19 13:45:47

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...
