Western rock lobster are sometimes called ‘crayfish’ or
‘crays’. They can live for over 20 years and reach sizes over
five kilograms, although fishing rules to protect the breeding
stock mean that animals over three kilograms are rarely
retained by fishers.
This lobster species belongs to the spiny lobster family,
which get their name from the hundreds of tiny forward-
pointing spines that cover their body and carapace, as well
as their most prominent feature – the two huge antennae
that protrude from their head. Whilst these antennae are
vital for spiny lobsters to find their way around, they also
form a crucial defensive weapon and communications tool.
