Coltro, Marcus |
Family: | Pinnidae (pen shells) | |||
Max. size: | 50 cm SHL (male/unsexed); max. reported age: 18 years | |||
Environment: | benthic; marine; depth range 0 - 50 m | |||
Distribution: | Indo-West Pacific: from East and southeast Africa, including Madagascar, Mauritius Island, the Red Sea and the Persian Gulf, to New Caledonia; north to Japan and south to South Australia. Generally absent from oceanic islands of the central Indian Ocean and the tropical West Pacific, but sporadically found in Hawaii. | |||
Diagnosis: | ||||
Biology: | Species of minor economic importance, and collected for subsistence fisheries (Ref. 348). Maximum depth from Ref. 101118. Embedded in muddy sand and reef flats, in littoral and adjacent subtidal shallow waters to depths of about 10 m (Ref. 348). Also found buried in hard substratum and associated with seagrass beds (Ref. 101119). Planktonic larval stage probably short, hence a range restricted to the shores of continental areas and adjacent island (Ref. 348). Small benthic Pinna may likely depend on dissolved organic matter for nutrition (Ref. 107096). | |||
