Chirodota Chirodota gigas


Photo of Chiridota the holothurianChirodota is the largest of the south-eastern holothurians, which are commonly called sea-cucumbers. It is sausage-like in shape, with a thin body wall and no tube feet. Holothurains have a five-sided body plan, like the sea stars, but it is horizontal, not vertical like other echinoderms.

The mouth and tentacles occur at one end to test the environment and the anus at the other end expels unwanted material.


Chirodota is easily recognised by its pinkish, reddish to orange colour, covered with numerous white spots. The white spots are clusters of tiny wheel-shaped calcareous spicules which provide a hardened protective layer.




Dendy & Hindle, 1907




250 - 500 mm


Chirodota ranges from central New South Wales, south to Victoria and most of Tasmania, with the exception of the far south coast. It is also found in New Zealand.


Chirodota occurs on reefs under rocks buried in sediment, at low tide levels and below to 10 metres.

It is occasionally found in rock pools at mid-tide level.
