# Clams, octopus, squid and other molluscs of Somalia: 339 species > Every bivalve, octopus, squid, cuttlefish and chiton species with a record from Somalia in GBIF, with class, family, Red List category and number of records. Source page: https://calankii.com/en/nature/clams-octopus-and-other-molluscs-of-somalia/ Last checked: 2026-11-13 Publisher: Calankii (https://calankii.com) ## In short On 12 November 2026 the Global Biodiversity Information Facility (GBIF), the international open database of species records, held records of 339 mollusc (other than snails) species with Somalia as the country, in 4 groups ([GBIF occurrence search, Somalia](https://www.gbif.org/occurrence/search?country=SO)). The largest groups by number of species on record are ([GBIF Backbone Taxonomy](https://doi.org/10.15468/39omei)): - Bivalvia: 288 - Cephalopoda: 37 - Polyplacophora: 13 - Caudofoveata: 1 ## Most often recorded The species with the most GBIF records from Somalia are Mirapecten cranmerorum (36), *Kuphus polythalamius* (18), noble scallop (16), *Nanogyra nana* (12), Bractechlamys nodulifera (11), *Grammatodon egertonianus* (10) ([GBIF occurrence search, Somalia](https://www.gbif.org/occurrence/search?country=SO)). 192 of the 339 species have a single record from Somalia (same source). ## Named after Somali places 8 species on this list carry Somalia or a Somali place in their scientific name, for example *Somalidacna lamellosa*, *Pholadomya somaliensis*, *Protocardia somaliensis*, *Ceromyopsis somaliensis*, *Mytilus somaliensis*, *Posidonia somaliensis*, *Trigonia somaliensis*, *Nautilus somaliensis* ([GBIF Backbone Taxonomy](https://doi.org/10.15468/39omei)). ## Species under threat The IUCN Red List places these species in a threatened category ([GBIF species API, IUCN Red List category](https://techdocs.gbif.org/en/openapi/v1/species)): - Endangered: eastern pearlshell ([IUCN via GBIF](https://techdocs.gbif.org/en/openapi/v1/species)) - Vulnerable: Bear Paw ([IUCN via GBIF](https://techdocs.gbif.org/en/openapi/v1/species)) ## How to read this list A species is on this list when GBIF holds at least one record of it from Somalia. A record can be a museum specimen more than a century old, a sighting shared by an observer, or a specimen cited in a scientific paper. Some records are old and a few may be misidentified, so this is a list of records, not of what lives in Somalia today. Names follow the GBIF Backbone Taxonomy, which can lag behind the newest research. ## Red List summary - Critically Endangered (CR): 0 - Endangered (EN): 1 - Vulnerable (VU): 1 - Near Threatened (NT): 0 - Least Concern (LC): 14 - Data Deficient (DD): 7 - Not Evaluated (NE): 316 Categories are from the IUCN Red List as published through GBIF ([GBIF species API, IUCN Red List category](https://techdocs.gbif.org/en/openapi/v1/species)). ## Largest families - Pectinidae: 36 species - Cardiidae: 22 species - Veneridae: 20 species - Mytilidae: 13 species - Hercoglossidae: 12 species - Limidae: 11 species - Malleidae: 11 species - Ostreidae: 11 species - Arcidae: 10 species - Pholadomyidae: 9 species ## Full list (339 species) Each name links to its Calankii page where one exists, otherwise to its GBIF species page. "Records in Somalia" is the number of GBIF occurrence records with Somalia as the country, counted on 12 November 2026 ([GBIF occurrence search, Somalia](https://www.gbif.org/occurrence/search?country=SO)). The same rows, with Wikidata ids and more columns, are in the open data file [species-recorded-in-somalia.csv](/data/nature/species-recorded-in-somalia.csv).
