American lobster (Homarus americanus) is a species of lobster found on the Atlantic coast of North America, chiefly from Labrador to New Jersey. It is also known as Atlantic lobster, Canadian lobster, northern lobster, Canadian Reds, or Maine lobster. It is sometimes called the true lobster or common lobster, but those names are ambiguous. It can reach a body length of 64 cm (25 in), and a mass of over 20 kilograms (44 lb), making it not only the heaviest crustacean in the world, but also the heaviest of all living arthropod species. Its closest relative is the European lobster Homarus gammarus, which can be distinguished by its coloration and the lack of spines on the underside of the rostrum. American lobsters are usually bluish green to brown with red spines, but several color variations have been observed.","source_id":"enwiki","source_url":"https://en.wikipedia.org/wiki/American_lobster","revision":1384704820,"licence":"CC BY-SA 4.0","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/","licence_tier":"amber","share_alike":true,"display_ok":true,"attribution":"Wikipedia contributors, “American lobster”","retrieved_at":"2026-11-11"}],"external_ids":[{"source":"gbif","label":"GBIF","external_id":"5972004","url":"https://www.gbif.org/species/5972004","match_type":"exact_accepted","confidence":1},{"source":"wikidata","label":"Wikidata","external_id":"Q37668","url":"https://www.wikidata.org/wiki/Q37668","match_type":"exact_accepted","confidence":1},{"source":"enwiki","label":"Wikipedia","external_id":"American lobster","url":"https://en.wikipedia.org/wiki/American_lobster","match_type":"external_id","confidence":1},{"source":"ncbi","label":"NCBI Taxonomy","external_id":"6706","url":"https://www.ncbi.nlm.nih.gov/Taxonomy/Browser/wwwtax.cgi?id=6706","match_type":"external_id","confidence":1},{"source":"itis","label":"ITIS","external_id":"97314","url":"https://www.itis.gov/servlet/SingleRpt/SingleRpt?search_topic=TSN&search_value=97314","match_type":"external_id","confidence":1},{"source":"eol","label":"Encyclopedia of Life","external_id":"46505674","url":"https://eol.org/pages/46505674","match_type":"external_id","confidence":1},{"source":"inaturalist","label":"iNaturalist","external_id":"61383","url":"https://www.inaturalist.org/taxa/61383","match_type":"external_id","confidence":1},{"source":"worms","label":"WoRMS","external_id":"156134","url":"https://www.marinespecies.org/aphia.php?p=taxdetails&id=156134","match_type":"external_id","confidence":1}],"sources":[{"source_id":"gbif","name":"GBIF Backbone Taxonomy","url":"https://www.gbif.org/dataset/d7dddbf4-2cf0-4f39-9b2a-bb099caae36c","licence":"CC BY 4.0","licence_url":"https://creativecommons.org/licenses/by/4.0/","citation":"GBIF Secretariat.
