Brown Rat

집쥐(Rattus norvegicus)는 IUCN 적색목록에서 관심대상(LC)으로 분류됩니다. 분포 범위 전반에 걸쳐 널리 서식하며 개체 수가 안정적으로 유지되고 있어 즉각적인 보전 우려가 없습니다.

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.
