The megamouth shark Megachasma pelagios (Lamniformes: Megachasmidae) was described in 1976 from a specimen caught off Hawaii (Taylor et al. 1983) and is the only extant member of its family and genus (Diez et al. 2022). From 1976 to 2010 M. pelagios was considered rare, with only 50 individuals recorded globally during that time (Nakaya 2010). In recent years it is apparent that it is more common and widespread than previously thought, with 273 confirmed records to date across 16 countries in the Atlantic, Indian and Pacific Oceans (Yu et al. 2021; Diez et al. 2022; Skelton et al. 2023). This species is classified as Least Concern on the IUCN Red List of Threatened Species, as it is globally distributed and does not appear to be heavily impacted by fisheries (Kyne et al. 2019).
巨口鲨 Megachasma pelagios（长尾鲨目：巨口鲨科）于 1976 年由在夏威夷捕获的一个标本描述（Taylor 等人，1983 年），是其科和属中唯一现存的成员（Diez 等人，2022 年）。从 1976 年到 2010 年，M. pelagios 被认为是稀有的，在此期间全球仅记录了 50 个个体（Nakaya 2010 年）。近年来，显然它比以前想象的更为常见和广泛，在大西洋、印度洋和太平洋的 16 个国家已有 273 个确认的记录（Yu 等人，2021 年；Diez 等人，2022 年；Skelton 等人，2023 年）。该物种在 IUCN 红色名录中被列为易危物种，因为它在全球分布，似乎没有受到渔业的严重影响（Kyne 等人，2019 年）。
