Old World sucker-footed bat description
This peculiar looking bat is one of only four sucker-footed bats in the world, and is found only on the island of Madagascar. Their prominent feature, and the origin of their name, is the horse-shoe shaped suction pads on the thumbs and soles. The Myzopoda sucker-footed bats differ from the other two sucker-footed bats in South America, as their suckers are not borne on small stalks. The large ears possess a tragus, and a unique small mushroom-shaped process lies at the base. The lips are wide, with the upper lip protruding significantly beyond the lower, and the thumb has a small vestigial claw. The fur varies from mid-brown to a rich golden-brown and is tinged with russet (2) (3). The long tail projects beyond the membrane that stretches between the arms, legs and elongated fingers to form the wings (4). The Old World sucker-footed bat was believed to be the only species in the genus Myzopoda until early 2007, when a new species (Myzopoda schliemanni) was discovered in Madagascar. It differs from Myzopoda aurita in the colour of its fur, its external measurements and features of the skull (5).Top
Old World sucker-footed bat biology
This rare and little studied bat is only known from a few specimens. What is known about it is that its remarkable suction pads enable it to cling to smooth vertical surfaces. Glands secrete a substance directly onto the surface of the suction pads to aid adhesion to a surface, creating a bond strong enough to support the bat’s entire body weight. One specimen was found roosting in the uncoiled leaf of the palm Ravenala madagascariensis and therefore it is presumed to roost in palms and similar vegetation. It roosts with the head uppermost whilst using the tail as a prop (2) (3). The Old World sucker-footed bat possesses a complex echolocation system and produces remarkably long calls, used to hunt insects, in particular small moths (2).Top

Old World sucker-footed bat threats
Like many other Malagasy species, the loss of forest habitat certainly poses a threat to the Old World sucker-footed bat. The forests of Madagascar face continuous and intensive pressure from encroaching agriculture, fire and over-exploitation, all intensified by growing human populations (7). However, the extent to which it may be impacted is hard to determine due to the lack of information regarding this species’ behaviour and ecology. If the Old World sucker-footed bat roosts primarily in Ravenala, its roost sites may be secure as this palm species is more common in secondary, rather than primary, forest (8).Top
Old World sucker-footed bat conservation
At present there are no known conservation measures in place specifically for the Old World sucker-footed bat, however it does occur in at least one protected area; the Ankarafantsika National Park in the Mahajanga Province. The IUCN/SSC Chiroptera Specialist Group outlines a number of conservation actions recommended for this species including carrying out further research on distribution and abundance, using radio-tracking to establish roosting and foraging requirements, and designating critical areas as reserves (8).Top
