The fossa is the largest mammalian carnivore on Madagascar and has been compared to a small cougar, as it has convergently evolved many cat-like features. Adults have a head-body length of 70–80 cm (28–31 in) and weigh between 5.5 and 8.6 kg (12 and 19 lb), with the males larger than the females.
The largest Aepyornis eggs are on average 3.3 mm (1 ⁄ 8 in) thick, with an estimated weight of approximately 10.5 kilograms (23 lb). [16] Eggs of Mullerornis were much smaller, estimated to be only 1.1 mm ( 3 ⁄ 64 in) thick, with a weight of about 0.86 kilograms (1.9 lb). [ 16 ]
This is a list of the native wild mammal species recorded in Madagascar.As of June 2014 (following the IUCN reassessment of the lemurs) there are 241 extant mammal species recognized in Madagascar, of which 22 are critically endangered, 62 are endangered, 32 are vulnerable, 9 are near threatened, 72 are of least concern and 44 are either data deficient or not evaluated.
Historically, the relationships of the Madagascar carnivorans have been contentious, but molecular evidence suggests that they form a single clade, now recognized as the family Eupleridae. [ 4 ] [ 5 ] [ 6 ] The hyena family, Hyaenidae, is a sister taxon of the euplerid and herpestid clade, and when grouped together with the viverrids and felids ...
The history of the fauna of Madagascar in the context of plate tectonics and paleoclimate over the last 200 million years (Aepyornithidae arrived later than is indicated). A good example of Malagasy convergent evolution is the fossa, a Malagasy carnivore that has evolved in appearance and behaviour to be so like a large cat that it was originally classified in Felidae, when it is in fact more ...
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. [18]
The eggs of Aepyornis are the largest known for any amniote, and have a volume of around 5.6–13 litres, and a length of approximately 26–40 centimetres (10–16 in) and a width of 19–25 centimetres (7.5–9.8 in). [13] The egg is about 160 times greater volume than a chicken egg. [16]
The Malagasy or striped civet (Fossa fossana), also known as the fanaloka (Malagasy, [fə̥ˈnaluk]) or jabady, [5] is an euplerid endemic to Madagascar. [6] It is the only species in genus Fossa. The Malagasy civet is a small mammal, about 47 centimetres (19 in) long excluding the tail (which is only about 20 centimetres (7.9 in)). It can ...
