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.

Great Hammerhead

가장 큰 귀상어 종으로, 큰귀상어는 최대 6미터에 달하며 전 세계 열대 및 아열대 연안 해역에 서식합니다. T자 형태의 독특한 머리(세팔로포일)는 전기 감지를 위한 감각 표면적을 크게 늘려, 모래 속에 숨어 있는 노랑가오리를 탁월한 정확도로 탐지할 수 있게 해줍니다—노랑가오리는 주요 먹이입니다. 높은 가치의 지느러미와 혼획 사망으로 인해 개체군이 급격히 감소하여 심각한위기종으로 분류되어 있습니다.
