Hi Bill,

Alex Martynov probably knows more, but the only information on the food of Colga pacifica that I am aware comes from a 1997 abstract by Grischenko and Martynov, cited in Martynov and Baranets (2002) and available via the link below, that C. pacifica and its congeners prey on arborescent and foliose bryozoans. No bryozoans are obvious in the in situ image of C. pacifica from Washington, but the resolution is not all that high.

The similarity of the radular teeth of species of Colga with known bryozoan specialists like species of Triopha and Polycera certainly also points to a diet of bryozoans.
