Its slender body may be more than 5 ft (1.5 m) long including the tail, which makes up about half of the total length, and the largest males may weigh as much as 26 lb (12 kg). The female is somewhat smaller. The coat is generally reddish brown above and cream below. The fossa is found in both humid and dry forests and is an agile climber. A generally solitary animal, it preys on lemurs, wild pigs, and other mammals as well as fish and birds; it hunts by ambush. During mating season several males compete for a female, who rests high in a tree; the tree may be used for mating, and then used as a mating ground by another female when the first leaves. There are two to four young in a litter. The young are blind and helpless when born, and remain the mother for about a year and a half. Largely because of habitat destruction, the fossa is endangered. The fossa is classified in the phylum ChordataChordata
, phylum of animals having a notochord, or dorsal stiffening rod, as the chief internal skeletal support at some stage of their development. Most chordates are vertebrates (animals with backbones), but the phylum also includes some small marine invertebrate animals.

The word is used in the approved name of such a surface feature on a planet or satellite.Fossa (Cryptoprocta ferox), a predatory mammal of the family Viverridae. The body measures as much as 76 cm in length and as much as 37 cm in height; the tail measures approximately 65 cm in length. The fossa, the largest predator of the island of Madagascar, has a massive body with relatively long, thick extremities and semiretractile claws. It somewhat resembles a cat, but the head is longer. The fur is short, smooth, and reddish brown. The fossa inhabits forests and feeds on birds and small mammals. It is terrestrial but may climb trees when chasing lemurs. It is active at night. The animal attacks domestic fowl and young domestic swine. REFERENCEMammals of the World, vol. 2. Baltimore, Md., 1964.fossa[′fäs·ə] (anatomy) A pit or depression.

Patient discussion about fossaQ. info on arachnoid cyst in the right posterior fossa A. Basically it's like a small sac filled with fluid. The problem is that the skull is a rigid closed space, which means that if there's something other than the brain, it'll occupy space, usually on expense of the brains' space. These kinds of problems are often referred to as "space occupying lesion".
It's usually congenital (i.e. develops during pregnancy), and even when it cause symptoms they develop slowly.
