Crab-eating raccoon range

The crab-eating raccoon, southern raccoon, or South American raccoon (Procyon cancrivorus) is a species of raccoon native to marshy and jungle areas of Central and South America (including Trinidad and Tobago). It is found from Costa Rica south through most areas of South America east of the Andes down to northern Argentina and Uruguay. [1] Despite its name, this species does not feed exclusively on crabs, and the common raccoon also seeks and eats crabs where they are available. In the Tupi–Guarani languages, it is known as aguará or agoará popé. [2]

Distribution

The crab-eating raccoon can be found in South America and parts of Central America. It can be found in Trinidad and Tobago, Panama, Colombia, Venezuela, Suriname, Guyana, French Guiana, Ecuador, Brazil, Peru, Bolivia, Paraguay, Uruguay, and Argentina. [1]

Diet and anatomy

The crab-eating raccoon eats crabs, lobsters, crayfish, other crustaceans, and shellfish, such as oysters and clams. It is an omnivore and its diet also includes, for example, small amphibians, fish, insects, [3] small turtles, [4] turtle eggs, fruits, nuts, and vegetables. [4] It resembles its northern cousin, the common raccoon, in having a bushy ringed tail and "bandit mask" of fur around its eyes. Unlike the common raccoon, the hair on the nape of the neck points towards the head, rather than backward. [5] The crab-eating raccoon also appears to be more adapted to an arboreal lifestyle than the common raccoon, with sharper, narrower claws. It also is better adapted for a diet of hard-shelled food, with most of the cheek teeth being larger than those of the common raccoon, with broader, rounded cusps. Although the crab-eating raccoon can appear smaller and more streamlined than the common raccoon due to its much shorter fur and more gracile build, the crab-eating raccoon is of similar dimensions to the northern species. Therefore, Allen's rule does not apply to the genus. Head and body length is 41 to 80 cm (16 to 31 in), tail length is 20 to 56 cm (8 to 22 in) and height at the shoulder is about 23 cm (9 in). Weights can range from 2 to 12 kg (4 to 26 lb), though are mostly between 5 and 7 kg (11 and 15 lb). [6] Males are usually larger than the females. It is a host of the intestinal parasite Pachysentis procyonis , an acanthocephalan whose species name is derived from the genus of the crab-eating raccoon. [7]

Behavior

The crab-eating raccoon is solitary and nocturnal, primarily terrestrial but will spend a significant amount of time in trees. It is almost always found near streams, lakes, and rivers. In Panama and Costa Rica, where it is sympatric with the common raccoon, it will be strictly found in inland rivers and streams, while the common raccoon lives in mangrove forests and swamps. In areas of sympatric range raccoons seen in the day time, in areas with people, in mangroves and in swamps will almost certainly be common raccoon. Less frequently, it will reside in evergreen forests or the plains, but are only rarely found in rainforests. [5] Compared to the common raccoon, which thrives in urban environments and adapts quickly to the presence of humans, the crab-eating raccoon adapts less easily and is much less likely to be found in human environments.

Reproduction

The crab-eating raccoon breeds between July and September, and gestation lasts between 60 and 73 days. Offspring are born in crevices, hollow trees, or abandoned nests from other creatures. Between two and seven kits are born, with three being the average. While typically crab-eating raccoons only breed once per year, if a female loses all her kits early in the season, they will mate again and have a second litter. Males have no part in raising young, and while attending to young, females will become much more territorial and will not tolerate other raccoons around them. [8]

It is occasionally found in the Azores and is a rare vagrant to Europe. An all-white population found in south Florida and the Florida Keys is known as the great white heron. Debate exists about whether these white birds are a color morph of the great blue heron, a subspecies of it, or an entirely separate species.

Procyon is a genus of nocturnal mammals comprising three species commonly known as raccoons in the family Procyonidae. The most familiar species, the common raccoon, is often known simply as "the" raccoon, as the two other raccoon species in the genus are native only to the tropics and are less well known. Genetic studies have shown that the closest relatives of raccoons are the ring-tailed cats and cacomistles of genus Bassariscus, from which they diverged about 10 million years ago.

The oilbird, locally known as the guácharo, is a bird species found in the northern areas of South America including the Caribbean island of Trinidad. It is the only species in the genus Steatornis, the family Steatornithidae, and the order Steatornithiformes. Nesting in colonies in caves, oilbirds are nocturnal feeders on the fruits of the oil palm and tropical laurels. They are the only nocturnal flying fruit-eating birds in the world. They forage at night, with specially adapted eyesight. However, they navigate by echolocation in the same way as bats, one of the few birds to do so. They produce a high-pitched clicking sound of around 2 kHz that is audible to humans.

<span class="mw-page-title-main">Mangrove crab</span> Crabs that live on or among mangroves

Mangrove crabs are crabs that live in and around mangroves. They belong to many different species and families and have been shown to be ecologically significant by burying and consuming leaf litter. Mangrove crabs have a variety of phylogenies because mangrove crab is an umbrella term that encompasses many species of crabs. Two of the most common families are sesarmid and fiddler crabs. They are omnivorous and are predated on by a variety of mammals and fish. They are distributed widely throughout the globe on coasts where mangroves are located. Mangrove crabs have wide variety of ecological and biogeochemical impacts due to the biofilms that live in symbiosis with them as well as their burrowing habits. Like many other crustaceans, they are also a human food source and have been impacted by humans as well as climate change.

The agouti or common agouti is any of several rodent species of the genus Dasyprocta. They are native to Middle America, northern and central South America, and the southern Lesser Antilles. Some species have also been introduced elsewhere in the West Indies. They are related to guinea pigs and look quite similar, but they are larger and have longer legs. The species vary considerably in colour, being brown, reddish, dull orange, greyish, or blackish, but typically with lighter underparts. Their bodies are covered with coarse hair, which is raised when alarmed. They weigh 2.4–6 kg (5.3–13.2 lb) and are 40.5–76 cm (15.9–29.9 in) in length, with short, hairless tails.

<span class="mw-page-title-main">Biota of Trinidad and Tobago</span>

Trinidad and Tobago are continental islands with a geologically very recent history of direct land bridge connection to South America. As a result, unlike most of the Caribbean Islands, Trinidad and Tobago supports a primarily South American flora and fauna and has greater diversity of plant and animal species than the Antilles. However, rates of endemism are lower than in the rest of the Caribbean because there has been less time for genetic isolation from mainland populations because of the history of land bridge connections and hence fewer opportunities for speciation, and so a greater proportion of the species in Trinidad and Tobago are also found on the South American mainland. Trinidad is nearer to mainland South America and has been directly connected to the mainland via land bridges more often and for longer periods than Tobago. This, as well as Trinidad's larger size and more varied topography and hydrology compared to that of Tobago allow greater species and ecosystem diversity on the former compared to that on the later of the islands.

Before drainage, the Everglades, a region of tropical wetlands in southern Florida, were an interwoven mesh of marshes and prairies covering 4,000 square miles (10,000 km2). The Everglades is both a vast watershed that has historically extended from Lake Okeechobee 100 miles (160 km) south to Florida Bay, and many interconnected ecosystems within a geographic boundary. It is such a unique meeting of water, land, and climate that the use of either singular or plural to refer to the Everglades is appropriate. When Marjory Stoneman Douglas wrote her definitive description of the region in 1947, she used the metaphor "River of Grass" to explain the blending of water and plant life.

<span class="mw-page-title-main">Raccoon</span> Medium sized mammal native to North America

The raccoon, also spelled racoon and sometimes called the common raccoon or northern raccoon to distinguish it from the other species, is a mammal native to North America. It is the largest of the procyonid family, having a body length of 40 to 70 cm, and a body weight of 5 to 26 kg. Its grayish coat mostly consists of dense underfur, which insulates it against cold weather. The animal's most distinctive features include its extremely dexterous front paws, its facial mask, and its ringed tail, which are common themes in the mythologies of the Indigenous peoples of the Americas surrounding the species. The raccoon is noted for its intelligence, and studies show that it is able to remember the solution to tasks for at least three years. It is usually nocturnal and omnivorous, eating about 40% invertebrates, 33% plants, and 27% vertebrates.

A unique and diverse albeit phylogenetically restricted mammal fauna is known from the Caribbean region. The region—specifically, all islands in the Caribbean Sea and the Bahamas, Turks and Caicos Islands, and Barbados, which are not in the Caribbean Sea but biogeographically belong to the same Caribbean bioregion—has been home to several families found nowhere else, but much of this diversity is now extinct.

The Amapá mangroves (NT1402) is an ecoregion along the Atlantic coast of the state of Amapá in Brazil. The low coastal plain has been formed from recent sedimentation, including sediments deposited by the rivers and sediments carried northward from the mouth of the Amazon River by strong currents and deposited by the tides. The extensive mangroves grow on the newly formed coastal mudflats and along the edges of estuaries. They merge into freshwater várzea flooded forests further inland. The ecoregion is generally well-preserved, although excessive extraction of natural resources including timber and shrimps is a concern.
