Habitat Details:

[British Columbia, Canada] intertidal (Forsyth and Harbo 2013) Holes/crevices in rocks; kelp holdfasts and giant barnacles at very low tide; foot appears to be specialized for gripping onto rock (Cowles 2005) Found in rock crevices, on shores covered in broken rocks, intertidally to 20 m (Sept 2009) Attaches byssally between rocks and in crevices (Yonge 1952; Morris et al. 1980, cited in Harper et al. 2009) Found in estuarine rocky intertidal; nestles/burrows in rock crevices and abandoned pholad burrows. Also attaches to floats/ pilings with byssal threads; adapts to rocky habitat by distorting its shell as it grows (Rudy et al. 2016) [Japan] Among the root of Phaeophyceae grows on the cobble or gravel at sea bottom or at tidal flat.

Natural Control:

PREDATION [Predation] Entodesma navicula (as Lyonsia saxicola (synonymized taxon) is prey for Octopus dofleini, at both subadult and adult stages (Gillespie et al. 1998) [Predation] Pycnopodia helianthoides (Cowles 2005) PARASITES [Parasites] E. navicula is host to ectoparasites Odostomia spp. (reported from British Columbia, Canada, and Alaska) and Evalea tenuisculpta (reported from British Columbia, Canada, and Washington, U.S.A.) (Harbo et al. 2012, cited in Bower 2013); they are small white snails; attach to mantle margin or directly to tip of siphon; penetrate the soft tissues with a stylet attached to a long extendible proboscis; extract fluids from hosts; large numbers ( > 20 per siphon) can cause irritation to tissue and disrupt feeding in the clam host; no deaths have been reported to date (Bower 2013)

Associated Species:

SYMBIONTS [Symbiont] symbiotic pea crab Pinnixa faba can be found in E. navicula (Cowles 2005) PARASITES [Parasites] E. navicula is host to ectoparasites Odostomia spp. (reported from British Columbia, Canada, and Alaska) and Evalea tenuisculpta (reported from British Columbia, Canada, and Washington, U.S.A.) (Harbo et al. 2012, cited in Bower 2013); they are small white snails; attach to mantle margin or directly to tip of siphon; penetrate the soft tissues with a stylet attached to a long extendible proboscis; extract fluids from hosts; large numbers ( > 20 per siphon) can cause tissue irritation and feeding cessation in the clam host; no deaths have been reported to date (Bower 2013)
