Eudistoma purpuropunctatum Lambert 1989
No full textEudistoma purpuropunctatum Lambert, 1989 Figure 3C IHAK 60 BHAK 3247 UF 2565. Rattenbury Pinnacle, Scuba, 17–20 m depth. Apparently not common; only one large colony 10 cm in diameter was collected during the three week survey. Morphology exactly as described by Lambert (1989). Tunic usually a pale lavender, though may be darker in areas with more dense purple pigment in the tunic. Colony encrusting, thickly irregular in shape. Known only from British Columbia and Washington (Lambert 1989; Lamb & Hanby 2005).Published as part of Lambert, Gretchen, 2019, The Ascidiacea collected during the 2017 British Columbia Hakai MarineGEO BioBlitz, pp. 401-436 in Zootaxa 4657 (3) on page 407, DOI: 10.11646/zootaxa.4657.3.1, http://zenodo.org/record/337188

Kwakshua Petroglyph Cliff, Scuba, 17–20 m, high current, vertical rock wall. Five colonies. IHAK 60 BHAK 3241 UF 2560. Rattenbury Pinnacle, Scuba, 17–20 m. On living unidentified scallop; with many small amphipods Polycheria osborni Calman, 1898 in burrows on tunic surface. The colonies are thick, encrusting and may attain a large size of 10 cm or more across and up to 2 cm in thickness. They are usually a dark purple or purplish brown in color, due to numerous pigment granules in the tunic and zooids. Small stellate tunic spicules are sparse. Colonies of what are probably this species were collected by dredging by Huntsman (1912a) near Nanaimo, British Columbia but identified only as dark colonies of Trididemnum sp. with sparse spicules. For complete description see Lambert (2003). Distribution: British Columbia to Washington (Lambert 2003; Lamb & Hanby 2005).Published as part of Lambert, Gretchen, 2019, The Ascidiacea collected during the 2017 British Columbia Hakai MarineGEO BioBlitz, pp. 401-436 in Zootaxa 4657 (3) on page 411, DOI: 10.11646/zootaxa.4657.3.1, http://zenodo.org/record/337188
