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。

common bobtail

The common bobtail (<em>Sepietta oweniana</em>) is a small cephalopod mollusc found in the coastal waters of Denmark, Norway, and Sweden. This species typically inhabits European marine ecosystems, often occupying shallow to moderately deep benthic environments along the coastline. As a member of the family Sepiolidae, the common bobtail is a squid-like creature well adapted to life on or near the seafloor. It is classified as Least Concern on the IUCN Red List, reflecting a stable population status across its European range. The species often uses cryptic coloration and burrowing behavior to avoid predation in its marine habitats. It is typically a carnivore, feeding on small crustaceans and fish, and is itself an important prey species for larger marine predators in the North Sea and surrounding waters. Biological traits of this species remain poorly documented in the scientific literature.
