In Brief ...
Mulu has the largest and some of the longest cave systems
found anywhere in the world. Combine this with the very wide
diversity of forest types and different altitudes found in
Mulu and the range of habitats becomes very large indeed.
As a result Mulu World Heritage Area is home to 30 different
species of bats.
In Deer Cave alone, the largest cave passage
in the World, there are 12 species of bats including the spectacularly
large colony of 3 million Wrinkled-lipped bats. This large
community of bats live, sleep, mate and have their babies in
the cave and can be seen most evenings streaming out of the
cave entrance and spiraling high into the night sky in search
Using 5 special cameras and infra-red lighting
(which cannot be seen by the bats) Mulu Bat-Cam is a world
first in bringing 'live' vision of tropical cave habitats to
Park visitors. No where else in the World can you watch millions
of bats deep inside a cave un-disturbed by humans, grooming,
squabbling and maneuvering through the inky darkness of the
cave using 'echo-location' the amazing ability to use sound
to navigate and hunt for food.
See amazing images of large unusual cave insects
living in total darkness that no longer have eye-sight but
have evolved long feelers to search for their food.
As the bats prepare to leave the cave, Mossy
Swiftlets that have been out feeding in the forest all day
are returning in their thousands. Both swiftlets and bats use
echolocation not only to avoid hitting the cave formations
and walls but also to stop mid air collisions.
Scientists are excited by this unique opportunity
to observe and study cave fauna, re-writing the text books
as new discoveries are recorded daily
