Salanoia
Salanoia is a genus of Malagasy carnivores ( Eupleridae ). It consists of two types of small predators, the simplicity mongoose ( Salanoia concolor ) and the 2010 described Salanoia durrelli.
Features
The species of the genus Salanoia like all Madagascan mongoose an elongated, slender body with short limbs. The skull is flat, the muzzle is elongated, the latter being somewhat duller than formed during the finishing Mungo at Salanoia durrelli. The fur of both species is at the top of dark brown ( at Salanoia durrelli lighter), the abdomen is reddish brown in the finishing Mungo and yellowish brown in Salanoia durrelli. In contrast to other Madagascan mongoose is no striae, and the tail is solid except for the peak at Salanoia durrelli.
The simplicity Mungo reaches a head-body length of 35-38 centimeters, Salanoia durrelli is probably somewhat smaller (the two individuals measured had a head-body length of 31 and 33 centimeters ), the bushy tail is in both species 16 to 20 and 21 inches long and the weight is 550 to 780 grams ( in Salanoia durrelli 600 and 675 grams).
Dissemination and lifestyle
Both species are endemic to Madagascar. The habitat of the finishing Mongoose are rainforests in the north-east of the island, on the Masoala Peninsula. They are primarily between 300 and 700 meters above the sea before, and occasionally up to 1000 meters. Salanoia durrelli is exclusively detected in the marshes of the Lac Alaotra in northeastern Madagascar.
Little is known about the life of both species, but especially of the described until 2010 Salanoia durrelli. Their diet consists mainly of the finishing Mungo insects, such as beetle larvae, while the stronger dentition Salanoia durrelli suggesting hartschaligere prey, such as crustaceans and molluscs.
System
The genus consists of two species, the simplicity mongoose ( Salanoia concolor ) and the 2010 described Salanoia durrelli.
Fanaloka ( fossa )

Narrow strip mongoose ( Mungotictis )
Ring-tailed mongoose ( Galidia )
While the genetic evidence clearly indicates that the Malagasy carnivores are a monophyletic group that is descended from a common ancestor, the internal system is more controversial. The Madagascan mongoose probably also form a monophyletic group - the position of the finishing mongooses and thus the genus Salanoia not exactly known ist.Durbin et al. 2010 Laying the basis of their investigation near a sister group relationship of the genus Salanoia with the narrow strip Mungo, the broad area Mungo appears the same as Schwersterart.
Endangering
Due to the destruction of their habitat, the finishing Mungo by the IUCN ( vulnerable ) is "at risk" as listed. There is no evidence for the hunting or predation by introduced species ( invasive species ), but these factors could pose a threat.
The habitat of Salanoia durrelli is due to pollution, habitat destruction for use by rice fields, over-fishing and the establishment of introduced species ( invasive species ) as the house rat (Rattus rattus ) and the Small Indian Civet ( Viverricula indica), a small carnivore, endangered. The Delacour Grebe ( Tachybaptus rufolavatus ), a bird species, their distribution was limited to this region, was in 2010 declared extinct and the population of the bamboo lemurs fell within five years by about 30% until 2001. As a species with a very restricted habitat who is at risk, and in competition with several introduced species, the population of this species is also likely to be at high risk, detection, however, has not yet taken place.
