suggests that the species even occurs off the Pacific coast of the Kuril Islands. The sponge is also suggested to occur in James Bay and SE Hudson Bay (Stewart & Lockhart 2005), but source material is not listed or available for taxonomic assessment and so those identifications cannot be presently confirmed. This is a shallow water species. The specimens in this study were found at
