General Description

Body cucumber shape, completely covered with tube feet, cream with mauve flecking and white tube feet. Up to 4 cm long.

Biology

Little is known about this new species. Like others in its genus, they usually bury vertically in sand or sediment and their tentacles may be seen extended above the sediment. Collection records of the related species, Thyone okeni, also exist from Victoria. However, these individuals are now thought to be significantly different suggesting that the correct identity of Thyone in Victorian waters requires further review.

Buried in sand or sediment, to depth of at least 2 m.
