[15] In a study of fossa diet in the dry deciduous forest of western Madagascar, more than 90% of prey items were vertebrates, and more than 50% were lemurs. Its claws are retractile, but unlike those of Felidae species, they are not hidden in skin sheaths. It is generally feared by the Malagasy people and is often protected by their fady (taboo). There is some sexual dimorphism, with adult males (weighing 6.2–8.6 kg or 14–19 lb) being larger than females (5.5–6.8 kg or 12–15 lb). The glans extends about halfway down the shaft and is spiny except at the tip. [40], Fossas are occasionally held in captivity in zoos. [4][9] Throughout the year, animals produce long-lasting scent marks on rocks, trees, and the ground using glands in the anal region and on the chest. [9][15] A suite of microsatellite markers (short segments of DNA that have a repeated sequence) have been developed to help aid in studies of genetic health and population dynamics of both captive and wild fossas. Eastern populations in Andringitra incorporate the widest recorded variety of prey, including both vertebrates and invertebrates. [4] The species name ferox is the Latin adjective "fierce" or "wild". [11][12][13] To reflect these relationships, all Malagasy carnivorans are now placed in a single family, Eupleridae. [17] The females do not have a pseudo-scrotum,[15] but they do secrete an orange substance that colors their underparts, much like the secretions of males. [4] In captivity, fossas are usually not aggressive and sometimes even allow themselves to be stroked by a zookeeper, but adult males in particular may try to bite.[16]. The generic name Cryptoprocta refers to how the animal's anus is hidden by its anal pouch, from the Ancient Greek words crypto- "hidden", and procta "anus". a multi-purpose construction vehicle, akin to a smaller version of a front-end loader or a backhoe (backhoe loader), with a one-man caged control cabin [15] To stimulate the male to mount her, she gives a series of mewling vocalizations. [4][15], Several of the animal's physical features are adaptions to climbing through trees. [4][15] It has medium brown eyes set relatively wide apart with pupils that contract to slits. [4] Unusually large individuals weighing up to 20 kg (44 lb) have been reported, but there is some doubt as to the reliability of the measurements. For its size, the fossa has a lower than predicted population density, which is further threatened by Madagascar's rapidly disappearing forests and dwindling populations of lemurs, which make up a high proportion of its diet. Indeed he looks younger than he did, by the loss of … However, if they wander into villages in search of domestic fowl, they may be killed or trapped. [8] The common name is the same as the generic name of the Malagasy civet (Fossa fossana), but they are different species. [15] The cubs do not take solid food until three months old,[20] and do not leave the den until they are 4.5 months old; they are weaned shortly after that. Does English Have More Words Than Any Other Language? [5] Its common name is spelled fossa in English or fosa in Malagasy, the Austronesian language from which it was taken,[4][6] but some authors have adopted the Malagasy spelling in English. However, an alternative etymology suggests a link to another word that comes from Malay: pusa refers to the Malayan weasel (Mustela nudipes). Recent research suggests that this system helps the fossa overcome factors which would normally impede mate-finding, such as low population density and lack of den use. « Matou » redirige ici.
