Chola guitarfish

The White-spotted Guitarfish (Rhinobatos albomaculatus) is a cartilaginous elasmobranch in the family Rhinobatidae, belonging to the guitarfishes — a group with a flattened, elongated body combining features of both rays and sharks. The species is distinguished by white spots on the dorsal surface, which give it its scientific epithet albomaculatus. It inhabits shallow coastal and estuarine waters of the tropical and subtropical western Atlantic and possibly the eastern Pacific, where it forages over sandy and muddy bottoms for small crustaceans, molluscs, worms, and fish. Like other rhinobatids, it reproduces viviparously, producing small litters of pups after a prolonged gestation period. The IUCN classifies Rhinobatos albomaculatus as Critically Endangered — one of the highest threat categories — reflecting severe population declines resulting from intensive bycatch in artisanal and commercial trawl fisheries across its restricted coastal range. Guitar rays globally are facing a conservation crisis; many species of Rhinobatidae have experienced rapid declines of 80% or more over recent decades in heavily fished coastal waters. The shallow, near-shore habitats they occupy offer no refuge from demersal fishing gears, and their low reproductive rate means recovery from depletion is extremely slow even if fishing pressure is reduced.

Emperor Penguin

세계에서 가장 큰 펭귄인 황제펭귄(Aptenodytes forsteri)은 키가 최대 1.2m에 몸무게가 45kg에 달하며, 지구상에서 가장 혹독한 환경인 남극 대륙에 서식합니다. 영하 60°C 이하의 한겨울 암흑 속에서 번식하며, 수컷이 암컷이 바다에 있는 동안 65일 동안 발 위에서 육아낭 아래에 알 한 개를 품습니다. 수천 마리가 모인 무리에서 개체들이 따뜻한 중심부를 순환하는 이른바 허들링 행동은 협동적 생존의 훌륭한 사례입니다.
