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.

Colares stingray

<em>Fontitrygon colarensis</em>, known as the Colares Stingray, is a ray in the family Dasyatidae. This species is classified as Critically Endangered on the IUCN Red List, indicating a very high risk of extinction in the wild. It is recorded in Venezuela and is associated with a diverse range of habitats including tropical and subtropical moist and dry broadleaf forests, grasslands, and at least six distinct biome types, suggesting it may occupy freshwater or coastal environments where such biomes interface. The genus <em>Fontitrygon</em> comprises freshwater and brackish-water stingrays found in South America and West Africa. Diet information for <em>Fontitrygon colarensis</em> is not available in provided records. Biological traits including body length, weight, and lifespan have not been documented for this species in available sources. Biological traits of this species remain poorly documented in the scientific literature. The Critically Endangered status of this ray underscores the urgency of conservation efforts and further scientific study to understand its biology, population size, and the threats driving its decline.
