Based on records dating from 1859 to 2021, we provide an overview of the marine animal diversity reported for Galiano Island, British Columbia, Canada. More than 650 taxa are represented by 20,000 species occurrence records in this curated dataset, which includes dive records documented through the Pacific Marine Life Surveys, museum voucher specim...

Glass sponges (Porifera, Hexactinellida) form globally unique reefs that support deep-sea biodiversity in the Canadian northeast Pacific. In February 2017, the largest known reefs were protected within the Hecate Strait and Queen Charlotte Sound Glass Sponge Reefs Marine Protected Area (HSQCS-MPA). Many studies that have established baseline biodiv...

Collections of sponges by the late Dr. William C. Austin and the authors (N. McDaniel, R. Harbo and B. Ott) provided material for descriptions of new species from two genera of Poecilosclerida for shallow waters of Southern British Columbia, Canada and Northern Washington, USA: Lissodendoryx and Myxilla. There have been no new species of these two...

Sea anemones of the genus Cribrinopsis Carlgren, 1921 from the NE Pacific are revised. Specimens traditionally identified from this region as Cribrinopsis fernaldi Siebert & Spaulding, 1976, actually represent two distinct species with different morphology and habitat. One species has long tentacles, a ring of distinct rounded marginal projections,...

Two small sea anemones, Octineon suecicum and Edwardsiella loveni, known previously only from scarce records in European waters, are reported from British Columbia, Canada. Both genera, Octineon and Edwardsiella were not previously reported from the North Pacific. It is speculated that both species have a wider distribution than it appears from sca...

A new genus and species of gall-forming endoparasitic copepod of the family Lamippidae is described from the orange sea pen Ptilosarcus gurneyi (Gray, 1860) collected in British Columbia, Canada. Lamippid copepods (over 50 species) are obligate endoparasites, some of which form galls in a variety of soft corals (Alcyonacea and Pennatulacea). Ptilos...

The hydroid Similiclava nivea, gen. nov., sp. nov., is described from colonies collected in nearshore waters of southern British Columbia, Canada. It has been observed by divers, and recorded as Clava sp., several hundred times at locations between southeast Alaska and southern Oregon, USA. While resembling the hydractiniid Clava multicornis, tenta...

The history of sponge collecting and systematics in British Columbia is reviewed over the period 1878 to 1966. Recent additions and changes are provided in an on-line species list: www.mareco/org/kml/projects/NEsponges.asp. Hadromerids are the focus of this paper as eight of 19 species in British Columbia are considered new. An additional new speci...

The paper describes two new species of sea anemones of the family Actiniidae, Urticina clandestina sp.n. and Aulactinia vancouverensis sp.n., recorded from British Columbia, Canada. Urticina clandestina sp.n. is unique in possessing gonads on all mesenteries of first cycles and thus attaining intermediate position between Urticina and Cribrinopsis....

AbstractTwo new species of Demospongiae are described for British Columbia and adjacent waters in the family Axinellidae, Auletta krautteri sp. n. and Dragmacidon kishinensis sp. n. They represent range extensions for both of these genera. Both are fairly commonly encountered, Auletta krautteri below diving depths (87 to at least 300 m) and Dragmac...

Urticina clandestina sp.n. and Aulactinia vancouverensis sp.n. (family Actiniidae) are recorded from British Columbia, Canada.

Praxillura maculata Moore (1923), quite unlike other maldanid polychaetes, constructs a membranaceous tube bearing 6 to 12 stiff radial spokes, each 25 to 30 mm long. These spokes radiate from the mouth of the tube and are arranged in almost a single plane approximately normal to its axis. A mucus web in which particles are passively caught is hung...
