About Manatee

Manatees (family.. Trichechidae, genus Trichechus) are large, fully aquatic marine mammals sometimes known as sea cows. The name manatí comes from the Taino which are the original peoples of the carribean, meaning "breast". They comprise three of the four living species in the order Sirenia, the other being the dugong, which is native to the Eastern Hemisphere. The Sirenia is thought to have evolved from four-legged land mammals over 60 million years ago, with the closest living relatives being the Proboscidea (elephants) and Hyracoidea (hyraxes).

Physical characteristics

The manatees differ from the dugong. Dugongs have a forked tail, similar in shape to a whale's, while manatees' tails are paddle-shaped. They are mainly herbivores, spending most of their time grazing in shallow waters and at depths of 1-2 metres (3-7 ft). Much of the knowledge about manatees is based upon research done in Florida and cannot necessarily be attributed to all types of manatees. Generally, manatees have a mean mass of 400-550 kg (900-1200 lb), and mean length of 2.8-3.0 m (9-10 ft), with maximums of 3.6 metres and 1,775 kg seen (the females tend to be larger and heavier). When born, baby manatees have an average mass of 30 kg.

On average, most manatees swim at about 5 km/h to 8 km/h (1.4 m/s to 2.2 m/s; 3 to 5 miles per hour). However, they have been known to swim up to 30 km/h (8 m/s; 20 miles per hour) in short bursts. Manatees inhabit the shallow, marshy coastal areas and rivers of the Caribbean Sea and the Gulf of Mexico (T. manatus, West Indian manatee), the Amazon basin (T. inunguis, Amazonian manatee), and West Africa (T. senegalensis, West African manatee). A fourth species, the dwarf manatee (T. bernhardi) was recently proposed for a population found in the Brazilian Amazon, although some have questioned its validity, instead believing it is an immature Amazonian manatee. Florida is usually the northernmost range of the West Indian manatee as their low metabolic rate makes cold weather endurance difficult. They may on occasion stray up the mid-Atlantic coast in summer. Half a manatee's day is spent sleeping in the water, surfacing for air regularly at intervals no greater than 20 minutes.

Florida manatees (T. m. latirostris) have been known to live up to 60 years, and they can move freely between different salinity extremes; however, Amazonian manatees (T. inunguis) never venture out into salt water. They have a large flexible prehensile upper lip that acts in many ways like a shortened trunk, somewhat similar to an elephant's. They use the lip to gather food and eat, as well as using it for social interactions and communications. Their small, widely spaced eyes have eyelids that close in a circular manner. Manatees are also believed to have the ability to see in color.

They emit a wide range of sounds used in communication, especially between cows and their calves, yet also between adults to maintain contact and during sexual and play behaviors. They may use taste and smell, in addition to sight, sound, and touch, to communicate. Manatees are capable of understanding discrimination tasks, and show signs of complex associated learning and advanced long term memory. They demonstrate complex discrimination and task-learning similar to dolphins and pinnipeds in acoustic and visual studies.

Manatees typically breed only once every other year, since gestation lasts about 12 months, and it takes a further 12 to 18 months to wean the calf. Only a single calf is born at a time and aside from mothers with their young or males following a receptive female, manatees are generally solitary creatures.

Manatees are herbivores and eat over 60 different plant species such as mangrove leaves, turtle grass, and types of algae, using their divided upper lip. An adult manatee will commonly eat up to 9% of its body weight (approx 50 kg) per day. Manatees have been known to eat small amounts of fish from nets.

Belize

About Belize

Belize (pronounced /b?'li?z/) is a country in Central America. It is the only officially English speaking country in the region. A British colony for more than a century, it was known as British Honduras until 1973, and became an independent nation in 1981. Belize is a member of the Caribbean Community (CARICOM), the Sistema de Integración Centroamericana (SICA), and the Commonwealth of Nations. With 8,867 square miles (22,960 km²) of territory and 297,651 people (Belize CSO, 2007 mid year estimate), the population density is the lowest in the Central American region and one of the lowest in the world. The country's growth rate is 3.5% (2006 estimate). It is bordered to the south and west by Guatemala, to the north and northwest by Mexico and to the east by the Caribbean Sea.

History

The Mopan Maya, were the original inhabitants of Belize. The Maya civilization spread itself over Belize beginning around 1500 BC, and flourished until about AD 900. European settlement began with the Baymen, British pirates, privateers and English seamen as early as 1638.

The origin of the name Belize is unclear, but one idea is that the name is from the Maya word belix, meaning "muddy water", applied to the Belize River. A less likely idea is that it derives from the Spanish pronunciation of the surname of the pirate who created the first settlement in Belize in 1638, Peter Wallace.

Another account believes the early settlement of "Belize in the Bay of Honduras" grew from a few habitations located at Belize Town and St. George's Caye into a de-facto colony of the United Kingdom during the late 18th century. In the early 19th century the settlement was called British Honduras, and in 1871 it became a Crown Colony.

Taking advantage of Spain's inability to establish control over present-day Belize, Englishmen began to cut logwood, a dyewood greatly valued in Europe as the principal dyestuff for the expanding wool industry. By the 1770s, a second tropical exotic timber, mahogany, replaced logwood as the main export from Belize. The economy of Belize remained based on the extraction of mahogany until the early 1900s when the cultivation of export crops such as citrus fruits, sugar cane, and bananas came to dominate the economy.

Hurricane Hattie inflicted significant damage upon Belize in 1961. The government decided that a coastal capital city lying below sea level was too risky. Over several years, the British colonial government designed a new capital, Belmopan, at the exact geographical centre of the country, and in 1970 began slowly moving the governing offices there.
