The Schliemann disc bat ( Myzopoda schliemanni ) is a bat species in the rabbit-mouth family . Their occurrence is limited to the northwest of the island of Madagascar .
features
The Schliemann disc bat is a relatively small bat, with a forearm length of around 45–49 mm. The tail is about 44 mm long and protrudes from the tail membrane. The back of the animals is brownish, the belly side is greyish. The suction cup-like pads on the wrists and ankles are striking. With the help of these balls, the bats can hold onto surfaces. Contrary to previous theories (active sucking or sticking), the animals stick to smooth surfaces through wet adhesion .
Way of life
Little is known about the way of life of the Schliemann disc bat. During the day, the animals usually rest in rolled up leaves of various types of palm, e.g. B. Ravenala madagascariensis . Animals have also been found in caves. Here they do not hang upside down like other bat species, but sit upside down, as sticking by means of wet adhesion does not work upside down.
The main food is butterflies and cockroaches , and to a lesser extent also beetles and hymenoptera . The discovery of a representative of the genus Monomorium could indicate that the bats also collect their prey from the surface of the vegetation. However, the food composition as well as other behaviors of the species require further research.
Danger
The IUCN does not assume any endangerment of the species, since the distribution area is large. In addition, the species seems to benefit from the ongoing destruction of the rainforests and the associated spread of Ravenala madagascariensis .
Etymology and history of research
The genus Myzopoda was considered monotypical with the Madagascan adhesive disc bat . It was not until 2007 that Myzopoda schliemanni was described as a separate species due to morphological differences in coat color and skeleton. Genetic studies also show Myzopoda schliemanni to be a separate species. The scientific name honors Harald Schliemann, who researched sticky disc bats for many years.
