Taxonomy Īlthough the maned wolf displays many fox-like characteristics, it is not closely related to foxes. Guará and aguará originated from tupi-guarani agoa'rá, "by the fuzz".
The term lobo, "wolf", originates from the Latin lupus. It is known locally as aguara guasu (meaning "large fox") in the Guarani language, or kalak in the Toba Qom language, lobo de crín, lobo de los esteros, or lobo colorado in Spanish, and lobo-guará in Portuguese. The term maned wolf is an allusion to the mane of the nape. In 2011, a female maned wolf, run over by a truck, underwent stem cell treatment at the Zoo Brasília, this being the first recorded case of the use of stem cells to heal injuries in a wild animal. The International Union for Conservation of Nature lists it as near threatened, while it is considered a vulnerable species by the Brazilian Institute of Environment and Renewable Natural Resources. It is very rare in Uruguay, possibly being displaced completely through loss of habitat. This mammal lives in open and semi-open habitats, especially grasslands with scattered bushes and trees, in the Cerrado of south, central-west, and southeastern Brazil Paraguay northern Argentina and Bolivia east and north of the Andes, and far southeastern Peru (Pampas del Heath only). It communicates primarily by scent marking, but also gives a loud call known as "roar-barking". The maned wolf is a crepuscular and omnivorous animal adapted to the open environments of the South American savanna, with an important role in the seed dispersal of fruits, especially the wolf apple ( Solanum lycocarpum). Its long, thin legs and dense reddish coat give it an unmistakable appearance. It is the largest canine in South America, weighing 20–30 kg (44–66 lb) and up to 100 cm (39 in) at the withers. It is the only species in the genus Chrysocyon (meaning "golden dog"). Its markings resemble those of foxes, but it is neither a fox nor a wolf. It is found in Argentina, Brazil, Bolivia, Peru, and Paraguay, and is almost extinct in Uruguay.
The maned wolf ( Chrysocyon brachyurus) is a large canine of South America. One heart circulates blood around the body, while the other two pump it past the gills, to pick up oxygen.Canis brachyurus, C. If the blood (called haemolymph in invertebrates) becomes deoxygenated - when the animal dies, for example - it loses its blue colour and turns clear instead.Īn octopus's three hearts have slightly different roles. The copper-based protein is more efficient at transporting oxygen molecules in cold and low-oxygen conditions, so is ideal for life in the ocean.
Well, the blue blood is because the protein, haemocyanin, which carries oxygen around the octopus's body, contains copper rather than iron like we have in our own haemoglobin. Finally, why do octopuses have blue blood?Īre you still wondering why octopus blood is blue and what the three hearts do? The researchers say they're not sure what the benefits of living in a densely populated settlement are for these octopuses, but it may just be a case of necessity, with limited den spaces available in the otherwise flat and featureless area. Frequent aggression, chases and even den evictions were observed among the octopuses living at Octlantis. City living has its advantages and drawbacks, as we all know.
