Chelipeds chelate and unequal in size and shape.......Callianassidae Family AXIIDAE The thin-shelled shrimp-like animals in this family are all burrowers and are found from shallow subtidal habitats to great depths. Recently Pemberton, Risk and Buckley (1976) determined that one species found off Nova Scotia makes burrows more than 2.5 m into the substrate. Obviously in abyssal regions the collection of these animals under such circumstances in particularly haphazard. Thus the number of specimens obtained is few and often these are damaged. Four species of this family are known to occur in the waters off British Columbia. All have one or two small hollow knobs of apparently unknown function on the mid-dorsal ridge of the carapace. These species have been assigned to the genera Axiopsis, Calastacus and Calocaris. The definitions of these genera were made when few species had been studied and recent discoveries indicate that the criteria used are not satisfactory. New genera will have to be created and the taxonomy of the Family revised. -

The Associates of Four Species of Marine Sponges of Oregon and Washington Abstract Approved Redacted for Privacy (Ivan Pratt, Major Professor)
AN ABSTRACT OF THE THESIS OF Edward Ray Long for the M. S. in Zoology (Name) (Degree) (Major) /.,, Date thesis presented ://,/,(//i $» I Ì Ì Title The Associates of Four Species of Marine Sponges of Oregon and Washington Abstract approved Redacted for Privacy (Ivan Pratt, Major Professor) Four species of sponge from the coasts of Oregon and Wash- ington were studied and dissected for inhabitants and associates. All four species differed in texture, composition, and habitat, and likewise, the populations of associates of each species differed, even when samples of two of these species were found adjacent to one another. Generally, the relationships of the associates to the host sponges were of four sorts: 1. Inquilinism or lodging, either accidental or intentional; 2. Predation or grazing; 3. Competition for space resulting in "cohabitation" of an area, i, e. a plant or animal growing up through a sponge; and 4. Mutualism. Fish eggs in the hollow chambers of Homaxinella sp. represented a case of fish -in- sponge inqilinism, which is the first such one reported in the Pacific Ocean and in this sponge. The sponge Halichondria panicea, with an intracellular algal symbiont, was found to emit an attractant into the water, which Archidoris montereyensis followed in behavior experiments in preference to other sponges simultane- ously offered. A total of 6098 organisms, representing 68 species, were found associated with the specimens of Halichondria panic ea with densities of up to 19 organisms per cubic centimeter of sponge tissue. There were 9581 plants and animals found with Microciona prolifera, and 150 with Suberites lata. -
