Cycads
belong to the division Cycadophyta. They were one of the dominant plant
forms back in the Mesozoic, the 'Age of the Dinosaurs', when they would
have comprised much of the forest as flowering trees do today. Many
species of cycads are toxic, containing the lethal compound macrozamin,
(including the species found in the rainforests here), and it has even
been suggested that this high toxicity initially evolved in this
ancient group to deter predation by dinosaurs.

Birds
 Pelican The seven species of Pelican can be found wherever there is water, all
around the world. They are all huge, instantly recognizable birds, with
large bills and big webbed feet. They are usually white, with additions
of yellow, pink, grey and/or black. Pelicans feed mainly on fish. The
bottom of the bill is extremely elastic and can carry large prey. When
it is fully distended, pelicans have a larger bill than any other bird.
Even though they look awkward on land, they are graceful swimmers. They
are also magnificent fliers, and have been found at heights of 3000
metres. The Australian Pelican is Australia’s largest flying bird, with
a wingspan of almost three and a half meters. It can be found wherever
there is water all around Australia and New Guinea, being especially
common around estuaries. Like many other pelicans around the world,
they can become quite tame, and can be found hanging around fishing
jetties and taking handouts. When not breeding, they are often nomadic,
having been recorded in New Zealand when there are droughts in
Australia. |

Mammals

There are about 15 species of 'Rock Wallabies', Petrogale spp. Many of
them look very similar to each other, and before the use of genetic
testing to determine species, there was were thought to be far fewer
species. They are generally very small kangaroos that live within rocky
outcrops.
