Lake Arari
Lake Arari () is a lake of Marajó, which itself is an island in the mouth of the Amazon. It is located in the state Pará in northern Brazil, divided between the municipalities Cachoeira do Arari and Santa Cruz do Arari. Slightly to the north-east lies Lake Guajará. Lake Arari has an ellipsoid shape, oriented in the north-south direction. The lake can be considered the largest depression ob the island Marajó. Geological surveys identify it as the remainder of a much larger lake that existed in the past. The waters of the lake are generally muddy in the dry season. During the wet season, the area and depth of the lake change considerably because of intensive flooding of the surrounding areas. The waters become more clear and the lake is visited by boto dolphins, manatees and piracuru fish. Caimans, snakes and poraquê electric eels can also be found, as well as various types of birds, such as scarlet ibises and herons. The lake is fed in the north by the Jenipapucu River ...

Marajó
Marajó () is a large coastal island in the state of Pará, Brazil. It is the main and largest of the islands in the Marajó Archipelago. Marajó Island is separated from the mainland by Marajó Bay, Pará River, smaller rivers (especially Macacos and Tajapuru), Companhia River, Jacaré Grande River, Vieira Grande Bay and the Atlantic Ocean. From approximately 400 BC to 1600 AD, Marajó was the site of an advanced pre-Cabraline society called the Marajoara culture, which may have numbered more than 100,000 people at its peak. Today, the island is known for its large water buffalo population, as well as the ''pororoca'' tidal bore periodically exhibited by high tides overcoming the usual complex hydrodynamic interactions in the surrounding rivers. It is the second-largest island in South America, and the 35th largest island in the world. With a land area of Marajó is comparable in size to Switzerland. Its maximum span is long and in perpendicular width. Geography ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Marajó Archipelago Environmental Protection Area
The Marajó Archipelago Environmental Protection Area () is an environmental protection area in the state of Pará, Brazil. It protects the Marajó Archipelago, made up of marine fluvial islands in the area where the Amazon and Tocantins rivers converge and flow into the Atlantic. Covering almost it is larger than some countries in Europe. The area is inhabited, but human activities are limited to some extent to reduce ecological damage. Location The Marajó Archipelago Environmental Protection Area (APA) is divided between the Pará municipalities of Afuá (14.2%), Anajás (11.78%), Breves (16.15%), Cachoeira do Arari (5.21%), Chaves (22.44%), Curralinho (6.09%), Muaná (6.37%), Ponta de Pedras (5.7%), Salvaterra (1.75%), Santa Cruz do Arari (1.69%), Soure (5.94%) and São Sebastião da Boa Vista (2.67%).

Echinochloa Polystachya
''Echinochloa polystachya'', the German grass, is a species of grass (family Poaceae), native to the New World Tropics and Subtropics, from Texas and Florida down to Argentina. It is an aquatic or semi-aquatic perennial that can grow in water as deep as . It is a useful fodder for water buffaloes, and to a lesser extent, cattle. In the Amazon floodplain it can reach productivity levels of in dry mass, one of the highest levels ever measured in natural vegetation and belongs to the C4 plants . Given that it occupies about of territory during the rainy season, it contributes on the order of 1% of the primary productivity of the planet.

Tartarugas River
The Tartarugas River () is a river of Marajó, which itself is an island in the mouth of the Amazon. It is located in the state Pará in northern Brazil, and forms the border between the municipalities Chaves and Soure. The source of Tartartugas River is in the swamp areas called '' mondongos'' that are normally flooded during the wet season. When the area around the source is flooded, it is sometimes called Lake Tartarugas (''Lago Tartarugas''). It has a connection to Lake Arari through the Jenipapucu River. It is fed by a stream called Igarapé Jararaca. Part of the river was canalised in the first half of the 20th Century, named the Tartarugas Canal (''Canal Tartarugas''). This was done to connect Lake Arari to the Atlantic Ocean, and also to facilitate drainage of the area in times of flooding. Because of this, the river can be navigated well. Along the river there are several elevations called '' tesos''. They contain indigenous cemeteries with human remains buried in cer ...

Heron
Herons are long-legged, long-necked, freshwater and coastal birds in the family Ardeidae, with 75 recognised species, some of which are referred to as egrets or bitterns rather than herons. Members of the genus ''Botaurus'' are referred to as bitterns, and, together with the zigzag heron, or zigzag bittern, in the monotypic genus ''Zebrilus'', form a monophyletic group within the Ardeidae. Egrets do not form a biologically distinct group from herons, and tend to be named differently because they are mainly white or have decorative plumes in breeding plumage. Herons, by evolutionary adaptation, have long beaks. The classification of the individual heron/egret species is fraught with difficulty, and no clear consensus exists about the correct placement of many species into either of the two major genera, ''Ardea (genus), Ardea'' and ''Egretta''. Similarly, the relationships of the genus, genera in the family are not completely resolved. However, one species formerly considered to c ...

Scarlet Ibis
The scarlet ibis, sometimes called red ibis (''Eudocimus ruber''), is a species of ibis in the bird family Threskiornithidae. It inhabits tropical South America and part of the Caribbean. In form, it resembles most of the other twenty-seven extant species of ibis, but its remarkably brilliant scarlet coloration makes it unmistakable. It is one of the two national birds of Trinidad and Tobago, and its Tupi–Guarani name, guará, is part of the name of several municipalities along the coast of Brazil. This medium-sized wader is a hardy, numerous, and prolific bird, and it has protected status around the world. Its IUCN status is Least Concern. The legitimacy of ''Eudocimus ruber'' as a biological classification, however, is in dispute. Traditional Linnaean taxonomy classifies it as a unique species, but some scientists have moved to reclassify it as a subspecies of a more general American ibis species, along with its close relative, the American white ibis (''Eudocimus albu ...

Electrophorus Electricus
''Electrophorus electricus'' is the best-known species of electric eel. It is a South American electric fish. Until the discovery of two additional species in 2019, the genus was classified as the monotypic, with this species the only one in the genus. Despite the name, it is not an eel, but rather a Gymnotiformes, knifefish. It is considered as a freshwater teleost which contains an electrogenic tissue that produces electric discharges. Taxonomic history The species has been reclassified several times. When originally described by Carl Linnaeus in 1766, he used the name ''Gymnotus electricus'', placing it in the same genus as ''Gymnotus carapo'' (banded knifefish) which he had described several years earlier. It was only about a century later, in 1864, that the electric eel was moved to its own genus ''Electrophorus'' by Theodore Gill. In September 2019, David de Santana et al. suggested the division of the genus into three species based on DNA divergence, ecology and habitat, ...

Caiman
A caiman ( (also spelled cayman) from Taíno language, Taíno ''kaiman'') is an alligatorid belonging to the subfamily Caimaninae, one of two primary lineages within the Alligatoridae family (biology), family, the other being alligators. Caimans are native to Central America, Central and South America and inhabit marsh, marshes, swamps, lakes, and mangrove rivers. They have scaly skin and live a fairly nocturnal existence. They are relatively small-sized crocodilians with an average maximum weight of depending on species, with the exception of the black caiman (''Melanosuchus niger''), which can grow more than in length and weigh in excess of 450 kg (1,000 Ib). The black caiman is the largest caiman species in the world and is found in the slow-moving rivers and lakes that surround the Amazon basin. The smallest species is the Cuvier's dwarf caiman (''Paleosuchus palpebrosus''), which grows to long. There are six different species of caiman found throughout the wate ...

Manatee
Manatees (, family (biology), family Trichechidae, genus ''Trichechus'') are large, fully aquatic, mostly herbivory, herbivorous marine mammals sometimes known as sea cows. There are three accepted living species of Trichechidae, representing three of the four living species in the order Sirenia: the Amazonian manatee (''Trichechus inunguis''), the West Indian manatee (''Trichechus manatus''), and the West African manatee (''Trichechus senegalensis''). They measure up to long, weigh as much as , and have paddle-like tails. Manatees are Herbivory, herbivores and eat over 60 different freshwater and saltwater plants. Manatees inhabit the shallow, marshy coastal areas and rivers of the Caribbean Sea, the Gulf of Mexico, the Amazon basin, and West Africa. The main causes of death for manatees are human-related issues, such as habitat destruction and human objects. Their slow-moving, curious nature has led to violent collisions with propeller-driven boats and ships. Some manatees h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jenipapucu River
The Jenipapucu River () is a river of Marajó, which itself is an island in the mouth of the Amazon. It is located in the state Pará in northern Brazil. The Jenipapucu River enters Lake Arari through its northern shore. It flows through the swamp areas called ''mondongos'' that are normally flooded during the wet season. It connects to the Tartarugas River through the Tartarugas Canal (''Canal Tartarugas''), created in the first half of the 20th century to connect Lake Arari to the Atlantic Ocean and to facilitate drainage of the area in times of flooding. The Jenipapucu River is often clogged by German grass and water hyacinths, making the passage of boats difficult. Along the Jenipapucu was a large '' fazenda'' owned by the Jesuits that employed slave labour. See also *List of rivers of Pará List of rivers in Pará ( Brazilian state).
