Grows to about 12mm. Has been found from the intertidal, where it is found on the underside of stones, to about 13m depth. It feeds on bryozoans with records of it eating Beania magellanica and Dictyocladium moniliferum. Note the distinctive rhinophores, with the large swollen posterior club, which seem characteristic of the genus. Species of Caldukia seem to be confined to New Zealand and southeastern Australia.
