They live in many habitats, including mud at upper bathyal depths
(say 600m+ for C. alertae). I have seem ROV images of C. foveauxanum
on dewatering chimneys at 300m; the chimneys stick out of the sandy
mud bottom. C. selectum lives on sandy bottoms midshelf. C.
punctulatum and its near-identical sympatric
C. granti live on intertidal rocks among mussels as well as on soft
midshelf sediments.
I believe they are sponge-eaters. So where there are sponges, there
too should be Calliostoma.
