Jimble Jellyfish have been sighted in Pittwater. If you plan on entering the water, you should be aware that these jellies are about.
The jimble belongs to the cubozoan family of jellyfish, which includes the infamous and deadly box jellyfish of northern Australia.
But the jimble is more of a painful nuisance and is found from Western Australia to southern Queensland.
They live in the clear waters of harbours and estuaries.
The jimble has a transparent, box-shaped bell, 3cm to 4cm long, and a trail of tentacles 10cm to 15cm long.
They are more common where the water is a little bit cooler; so in our waters, rather than up north.
