Summary
editDescription(49110401488) - Lemuriformes.jpg |
English: Species: Lemur, The ring-tailed lemur (Lemur catta) is a large strepsirrhine primate and the most recognized lemur due to its long, black and white ringed tail. It belongs to Lemuridae, one of five lemur families, and is the only member of the Lemur genus. Like all lemurs it is endemic to the island of Madagascar. Known locally in Malagasy as maky, spelled maki in French) or hira, it inhabits gallery forests to spiny scrub in the southern regions of the island. It is omnivorous and the most terrestrial of lemurs. The animal is diurnal, being active exclusively in daylight hours.
The ring-tailed lemur is highly social, living in groups of up to 30 individuals. It is also female dominant, a trait common among lemurs. To keep warm and reaffirm social bonds, groups will huddle together. The ring-tailed lemur will also sunbathe, sitting upright facing its underside, with its thinner white fur towards the sun. Like other lemurs, this species relies strongly on its sense of smell and marks its territory with scent glands. The males perform a unique scent marking behavior called spur marking and will participate in stink fights by impregnating their tail with their scent and wafting it at opponents. As one of the most vocal primates, the ring-tailed lemur uses numerous vocalizations including group cohesion and alarm calls. Experiments have shown that the ring-tailed lemur, despite the lack of a large brain (relative to simiiform primates), can organize sequences, understand basic arithmetic operations and preferentially select tools based on functional qualities. Despite reproducing readily in captivity and being the most populous lemur in zoos worldwide, numbering more than 2,000 individuals, the ring-tailed lemur is listed as Endangered by the IUCN Red List due to habitat destruction and hunting for bush meat and the exotic pet trade. De ringstaartmaki (Lemur catta) is een vrij grote en het enige soort van het geslacht ringstaartmaki's (Lemur). De ringstaartmaki is het enige soort, hoewel de soorten uit de geslachten van de vari's (Varecia) en echte maki's (Eulemur) lang tot Lemur gerekend werden. De ringstaartmaki is waarschijnlijk de bekendste lemur; de soort wordt in veel dierentuinen gehouden. De ringstaartmaki werd in 1608 ontdekt door de handelaar William Finch. De vacht is grijsbruin van kleur. De kop, onderzijde, handen en de binnenzijde van de ledematen zijn wit. De kop, het gebied rond de ogen en de snuit is zwart. Deze gezichtstekening benadrukt de gezichtsuitdrukkingen. De lange pluimstaart heeft veertien witte ringen, afgewisseld met zwarte ringen. De ogen zijn goudgeel van kleur. De huid is zwart. Mannetjes verschillen van vrouwtjes door een kortere snuit en bredere schouders. De achterpoten zijn langer dan de voorpoten. Ook de voeten zijn lang. Beide handen en voeten hebben vijf vingers en tenen. De duim is opponeerbaar, en alle vingers en tenen, met uitzondering van de tweede teen, hebben nagels. De tweede teen heeft een "kamklauw". Met deze kamklauw kan de ringstaartmaki luizen verwijderen, zowel bij zichzelf als bij andere maki's. De ringstaartmaki weegt gemiddeld twee kilogram. Hij wordt 39 tot 46 centimeter lang. De staart wordt net zo lang als de rest van het lichaam. |
