Luidia australiae, the southern sand star, is a species of starfish in the family Luidiidae. It is found in the Pacific Ocean around Australia and New Zealand.
Description
Luidia australiae has a variable number of long, slim, tapering arms but seven is the most common number. The central disc and the arms are a dull yellow colour, irregularly blotched with dark green or black. It can grow to 40 centimetres (16 in) in diameter.[2][3]
Distribution and habitat
Luidia australiae is native to the waters around southern Australia and New Zealand. It is found on reefs, in seagrass meadows, and semi-buried in sand at depths of up to 110 metres (360 ft). It is sometimes washed ashore after storms.
Biology
Luidia australiae is a carnivore and is often found half-buried in the sediment in seagrass beds where its colouring provides camouflage. It is likely to be an opportunist predator of macrofauna, and possibly also a scavenger.[3]
