Seychelles sheath-tailed bat Coleura seychellensis
Evolution Ecology Conservation

sheath-tailed batsThe Seychelles sheath-tailed bat is a Critically Endangered species now restricted to just two of the Seychelles islands. It was the 25th EDGE (Evolutionarily Distinct and Globally Endangered) species listed by the Zoological Society of London and is a trigger species for the Alliance For Zero Extinction. In 2012 it was highlighted by the Bat Specialist Group as one of the species most likely to become extinct in the near future.

Conservation of the Seychelles sheath-tailed bat was initiated by the Nature Protection Trust of Seychelles which studied the species from 1997 until 2010. Active conservation work saw the population managed by NPTS rise from 18 bats to a maximum of 40. These low figures are an indication of the precarious status of this bat.
