Machine translation, like DeepL or Google Translate, is a useful starting point for translations, but translators must follow the LLM translation guideline, revise errors as necessary and confirm that the translation is accurate, rather than simply copy-pasting machine-translated text into the English Wikipedia.

Acanthosepion is a genus of cuttlefish, long thought to be a subgenus of the cuttlefish type genus, Sepia. A 2023 paper revived several genera of cuttlefish and elevated some subgenera of Sepia to full genus level based on molecular sequencing; this study recovered Acanthosepion as a distinct clade of cuttlefish. Genus Acanthosepion was determined to range from the coast of South Africa and Western Australia up to the Red Sea, Persian Gulf, and north to Sakhalin.[2] This classification scheme has been accepted by various databases, such as WoRMS,[1] and GBIF.[3]
