Cuttlebone, Sepia sp. © Queensland Museum, Jeff Wright. Cuttlebone
Cuttlebones are hard, ridged, shield-like objects that have a soft spongy inner layer and are frequently found on beaches, often in great clumps after storms. They are in fact the internal shells of cuttlefish, relatives of the octopus and squid. There are many species worldwide and several unique ones in Queensland’s waters.

Day Octopus, Octopus cyanea. © Queensland Museum, Gary Cranitch. Cephalopods
This entirely marine class includes such familiar animals as the octopus, cuttlefish and squid and also the so-called ‘living-fossil’ Nautilus and the extinct ammonites. As the name suggests the limbs are closely associated with the head, and in most cephalopods these limbs (arms and tentacles) possess numerous suckers which help to secure prey. Many species of squid, octopus and cuttlefish are of major commercial importance (primarily as seafood).

The Red-rumped Wisp is a tiny damselfly that inhabits a variety of standing water habitats, including small, well-vegetated ponds, dams and swamps. It is very similar to the Pgymy Wisp but males have more of the tip of the abdomen reddish. However, only female Red-rumped Wisps are known from south-east Queensland.
