Pascula cf muricata (Reeve, 1846)

These resemble published figures of Pascula muricata but seem a bit more ovoid and have smaller spiral ridges of bumps between the larger ones. These are abundant under rocks and in Halimeda algae patches along lagoon reefs, and can be found on a range of other lagoon, pinnacle and seaward reefs as well, including in the intertidal.

This one appeared to be drilling through the shell of a small clam, Glycodonta.

This one was on and apparently eating a burrowing echinoid.
