A list of 260 species from central California to southern Alaska is recorded by Austin (1985). Austin and Ott provided a key to 130 species known from British Columbia and Washington (Kozloff, 1987).

This annotated list of approximately 290 species is an update of the 1985 list noted above. Approximately 230 of these species are recorded in  BC and adjacent waters. The 159 highlighted species names include photos of specimens. The list includes some undescribed species (unnamed) but is not intended as a medium for formal species descriptions. Underwater photographs were largely taken  by Neil McDaniel (McDaniel Photography, Vancouver, BC).

Welton Lee, David Elvin and Henry Reiswig (2007) have produced a major guide to the sponges of California while Bob Stone, Helmut Lehnert and Henry Reiswig (2011) have produced a guide to the deep water sponges in the Aleutians. We hope that, ultimately, a revised list will incorporate the work of all spongologists along the NE Pacific coast. Please note that the list at this time is a draft copy subject to updates and corrections.


Many people helped in field surveys and collection including: Myriam Preker ( Bamfield Marine Station), Mile LeBlanc and Ray Anderson (Univ. British Columbia), Jeff Marliave (Vancouver Public Aquarium), Verena Tunnicliffe (Univ. Victoria), Kim Conway & J. Vaughn Barrie (Pacific Geoscience Centre), Henry Reiswig (Univ. Victoria), Welton Lee (California Acad. Sciences), Bjorn Gulliksen (Univ. Tromso), and Manfred Krautter (Univ. Stuttgart). Jeff Goddard (Univ. Cal., Santa Barbara, and Jerry Bakus (Univ. Southern California) who provided some updates on his collections in the Puget Sound region in the 1960s. Neil McDaniel was assisted on many SCUBA dives by Geoff Grognet and Doug Swanston.

Photos other than those of the authors were provided by Rick Harbo (Fisheries & Oceans, Canada, ret._, Brent Cooke and Phil Lambert, ret. (BC Provincial Museum), Ron Long (Simon Fraser Univ.) and Frank Bernard (Pacific Biological Station), Ralph Brinkhurst & Doug Moore (Institute of Ocean Sciences), and Rob Van Syoc (California Academy of Sciences).
