Do your kids love exploring rock pools? Then be cautious about this aggressive competitor that has the potential, in the right conditions, to alter our precious intertidal communities in a significant way - it could even suffocate our beloved green-lipped mussel beds. Currently only found on the West Coast of the Far North. We don’t want it spreading further.

How to identify this species:

• Sack-like body 

• Brown to reddish brown, leathery skin

• Flat surface surrounded by ridge with 2 siphons

• 2 siphons in cross pattern

• Often surrounded by shell, rubble, sand
