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.

Common Seal

가장 널리 분포하는 기각류인 항구물범(Phoca vitulina)은 북대서양과 북태평양 양쪽의 온대 및 아북극 연안에 서식한다. 성체는 최대 130kg에 달하며 바다에서 어류·오징어·갑각류를 사냥하고 해변이나 바위 위에서 쉬며 비슷한 시간을 보낸다. 크고 표정 풍부한 눈은 저조도 수중 시야에 적응되어 있다. 범고래·상어·북극곰의 중요한 먹이원이다.
