Hear all about it!Western Rock Lobsters is one of about 8 species of rock lobster found in WA’s waters. It only occurs in continental shelf waters off the Australian west coast and is common in the waters off Rottnest Island.
These animals feed mostly at night and live together in big groups in and amongst the limestone and coral reefs. They hide in caves or under ledges, often living in groups in bigger caves. Their thick armour and spiny surface helps protect them from predators but sheltering in numbers offers greater protection. When attacked, the lobster or group of lobsters will back into a cave with their spines and spiky antennae pointing aggressively forward.
These antennae are also vital for the lobster to find its way around and a communication tool. Western Rock Lobsters grow slowly taking five years to reach maturity and some of the large lobsters may be up to 30 years old or more. They are the target of WA’s largest and most valuable fishery.
Threats include; overfishing and pollution.
