Malagasy civet


By Evan Hyatt

Kingdom: Animalia
Phylum: Chordata
Subphylum: Vertebrata
Class: Mammalia
Order: Carnivora
Family: Eupleridae
Genus: Fossa
Species: Fossa fossana

Geographic Range

The Malagasy Civet or Striped Civet (Fossa fossana) is native to and located throughout Madagascar only.

Biogeographic Regions
ethiopian (Native )

Other Geographic Terms
island endemic

Habitat

Fossa fossana is found throughout most of Madagascar, from humid lowland forests to dryer higher elevations.

Habitat Regions
tropical

Terrestrial Biomes
rainforest ; scrub forest

Physical Description

Range mass
1.5 to 2 kg
(3.30 to 4.41 lb)

Range length
40 to 45 cm
(15.75 to 17.72 in)

Average basal metabolic rate
5.02262 W
[External Source: AnAge]

Fossa fossana has a body length between 40 and 45 cm plus a tail that is 21 to 25 cm is length, with the female usually being longer. They weigh between 1.5 and 2 kg. with the male weighing more.

They have short, dense fur which is a brownish color and has 4 rows of dark spots running along the back. The ventral side is more lightly colored. The face resembles that of a fox, with a body about the size and shape of a house cat.

Other Physical Features
endothermic ; bilateral symmetry

Reproduction

Fossa fossana form pairs around the time of mating, and each pair may have a home range of about a square mile during the mating season.

Mating System
monogamous

Breeding season
August - September

Range number of offspring
1 to 1

Average number of offspring
1
[External Source: AnAge]

Average gestation period
3 months

Average gestation period
82 days
[External Source: AnAge]

Average birth mass
67.5 g
(2.38 oz)
[External Source: AnAge]

Range time to weaning
2 to 3 months

Average age at sexual or reproductive maturity (female)
Sex: female

728 days
[External Source: AnAge]

Mating occurs during August and September with a single young being born after three months. The young have a full coat of fur, and their eyes are open at birth. They walk around day three, eat meat after a month, and are weaned at two to three months.

Key Reproductive Features
seasonal breeding ; gonochoric/gonochoristic/dioecious (sexes separate); sexual ; fertilization (Internal ); viviparous

The young stay with the parents until about one year of age, when they move on to find their own home ranges.

Lifespan/Longevity

Average lifespan
Status: captivity

21.4 years
[External Source: AnAge]

Behavior

They store fat reserves in their tales for the winter, which can total up to about 25 percent of their total body weight.

Mating pairs mark they territory with scent. These scents are produced from anogenital, cheeck, and neck glands.

Key Behaviors
nocturnal ; territorial

Food Habits

Fossa fossana eat small mammals including rodents and tenrecs. They also feed on reptiles, frogs, small birds, and invertebrates including freshwater crabs.

They forage on the ground and in low trees and brush, and are usually active at night.

Predation

Malagasy civets have very few natural predators as adults, but young animals may be eaten by snakes, birds, and other predators. They are also sometimes preyed upon by dogs that have been introduced to madagascar, and they are hunted by humans for food.

Fossa fossana uses camoflauge and the fact that it is nocturnal to avoid predators.

Ecosystem Roles

Fossa fossana fills the ecological niche most commonly filled by fox or cat like animals.

Economic Importance for Humans: Positive

The Striped Civet is beneficial to humans because it is hunted for food. It is also a popular attraction for tourists who can photograph it rather easily because it can be attracted to bait stations.

Positive Impacts
food ; ecotourism

Conservation Status

IUCN Red List [Link]
Vulnerable

US Federal List [Link]
No special status

CITES [Link]
Appendix II

The current listing is based on a suspected population decrease in a range larger or equal to 20% over the last 10 years, along with a decrease in the size and quality of the habitat. The decrease is furthered by trapping of the civets for food, and competition with the Small Indian Civet (Viverricula indica)

Other Comments

The Striped Civet is the second biggest Madagascar carnivore after the Fossa (C~ryptoprocta ferox~). Most likely, an early uncertainty in the differences of these two animals has been continued in the similarity of the Malagasy name for one and the scientific name of the other.

There used to be a larger species of Fossa that is now extinct.
