The fossa (Cryptoprocta ferox; / ˈ f ɒ s ə / FOSS-ə or / ˈ f uː s ə / FOO-sə; [3] Malagasy:) is a slender, long-tailed, cat-like mammal that is endemic to Madagascar. It is a member of the carnivoran family Eupleridae .
The fossa of Madagascar looks like a small cat. ... While most plant species are perennial, about 6% follow an annual life cycle, living for only one growing season ...
In biology, a biological life cycle (or just life cycle when the biological context is clear) is a series of stages of the life of an organism, that begins as a zygote, often in an egg, and concludes as an adult that reproduces, producing an offspring in the form of a new zygote which then itself goes through the same series of stages, the ...
The fossa (Cryptoprocta ferox) is a smaller relative of C. spelea that still survives.. Although some morphological differences between the two fossa species have been described, [17] these may be allometric (growth-related), and in their 1986 Mammalian Species account of the fossa, Michael Köhncke and Klaus Leonhardt wrote that the two were morphologically identical.

fossa ovalis: ductus arteriosus: ligamentum arteriosum: extra-hepatic portion of the fetal left umbilical vein: ligamentum teres hepatis ("round ligament of the liver") intra-hepatic portion of the fetal left umbilical vein (ductus venosus) ligamentum venosum: proximal portions of the fetal left and right umbilical arteries
During proestrus and estrus, females may have a clear, blood tinged, or bloody discharge. Dogs during these stages are often informally referred to as being in heat. The length of these cycles varies greatly among breeds and even between individuals of the same breed. Proestrus and estrus can last anywhere from 5 days to 21 days. [5] 3.
The fossa consists of three parts, superior, intermediate, and inferior: The superior part The superior part is triangular in shape and limited laterally by the superior cerebellar peduncle; its apex, directed upward, is continuous with the cerebral aqueduct; its base is represented by an imaginary line at the level of the upper ends of the superior foveae.
Each ovary is whitish in color and located alongside the lateral wall of the uterus in a region called the ovarian fossa. The ovarian fossa is the region that is bounded by the external iliac artery and in front of the ureter and the internal iliac artery. This area is about 4 cm x 3 cm x 2 cm in size. [3] [4]
