blue whale
지구에서 살았던 것으로 알려진 가장 큰 동물로, 대왕고래(Balaenoptera musculus)는 33미터, 200톤에 달할 수 있으며, 심장만도 소형 자동차 무게와 비슷합니다. 모든 대양에 서식하며, 극지방 먹이 지역과 열대 번식 지역 사이를 이동합니다. 하루 최대 4톤의 크릴새우를 섭취하는 여과 섭식자입니다. 20세기 포경으로 인한 거의 멸종 이후 전 세계 개체수가 10,000~25,000마리로 추정되는 멸종위기 종입니다.
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.
