大翅鯨

座头鲸是大型鲸类中最具杂技表演性的物种之一，以繁殖季节雄性演唱的复杂而神秘的歌声著称，歌声有时持续数小时并随时间演变。体长可达16米，体重30吨，进行着哺乳动物中最长距离的洄游。分布于所有大洋，通过协作泡泡网捕食磷虾和小鱼。种群数量已从历史捕鲸后大体恢复。

Comoro cat shark

<em>Scyliorhinus comoroensis</em>, the Comoro catshark, is a small demersal shark in the family Scyliorhinidae. As its name suggests, it is associated with the waters around the Comoro Islands in the western Indian Ocean, where it was first described from specimens collected in the region. Like other catsharks, it is a bottom-dwelling species adapted to life on or near the seafloor, typically inhabiting continental and insular shelf and slope environments. Biological traits including average lifespan, body length, body weight, and dietary preferences remain poorly documented due to the species' limited range and the scarcity of specimens available for study. Based on comparisons with related scyliorhinid species, it likely feeds on small fish, cephalopods, and invertebrates. The species is currently assessed as Data Deficient by the IUCN, reflecting the limited information available on its distribution, population size, ecology, and response to potential threats such as bycatch in artisanal and commercial fisheries operating in the Comoros region. Dedicated surveys and additional specimen collection are needed to improve knowledge of <em>Scyliorhinus comoroensis</em> and to determine appropriate conservation measures.
