'DID YOU KNOW ABOUT' the Red Rock Lobster? The Southern Rock Lobster, Red Rock Lobster or Spiny Rock Lobster ( Māori name kōura), is a species of spiny lobster found throughout coastal waters of southern Australia and New Zealand including the Chatham Islands. They live in and around reefs at depths ranging from 5–200 metres (16–660 ft) deep at the continental shelf. They can be dark red and orange above with paler yellowish abdomens or grey green brown with the paler underside. The more tropical animals tend to have the brighter colours. Adults can grow up to 230 millimetres (9.1 in) in length and can often exceed 8 kilograms (18 lb) in underfished areas. They are carnivorous, leaving their rock cover to venture out to feed during the night and typically eat live prey such as fish, molluscs, other crustaceans, worms and some plant life. They are also known to scavenge, if necessary.
