Coleura seychellensis (Seychelles sheath-tailed bat)

Wikipedia Abstract

The Seychelles sheath-tailed bat (Coleura seychellensis) is a sac-winged bat. It occurs in the central granitic islands of the Seychelles. It was probably abundant throughout the Seychelles in the past, but it has declined drastically and is now extinct on most islands.It is one of the most endangered animals, fewer than 100 are believed to exist in the world. The Seychelles sheath-tailed bat has suffered from habitat deterioration due to the effects of introduced plant species.

EDGE Analysis

This bat belongs to an ancient family of sheath-tailed bats, so-called because of the nature of the membrane which stretches between the hind legs. By adjusting the hind legs in flight, this membrane can be lengthened or shortened as it slips over the tail, increasing manoeuvrability in flight. Previously common on the Seychelles Islands, this bat has undergone a severe population decline over the past 30 years. Less than one hundred bats are believed to survive today, in just two locations. Conservation programmes require support in order to ensure that this species has a future.
