Koonac
Cherax pleloejus/ Cherax glaber

koonac.jpg (4756 bytes)Koonacs are dark blue to muddy brown in colour and can be up to 20cm in length. They have two broad spade-like claws with inner serations. There are white spots visible on upper surface and head, and four short ridges are also visible on the head.

Their means of reproduction involves external fertilisation.

Koonacs thrive in inland rivers and swamps that seasonally dry up. To escape drought koonacs burrow, into the banks of the dried up waterways.

Koonacs are not threatened, and were introduced into Koopoolang Pond in spring 1999.
