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.

Collared Gnatwren

<em>Microbates collaris</em>, the Collared Gnatwren, is a small insectivorous bird in the family Polioptilidae. This species is assessed as Least Concern on the IUCN Red List. It is documented in Colombia, Ecuador, and Venezuela, inhabiting the understory of humid tropical forests in lowland and foothill areas. The genus <em>Microbates</em> comprises the gnatwrens, small, wren-like birds that creep through dense undergrowth searching for insects and other arthropods. The Collared Gnatwren is named for the dark collar visible on its throat and breast, which contrasts with its white underparts. It tends to remain low in the forest understory and can be difficult to observe despite being heard more readily. Diet, population estimates, population trend, and biological measurements including average length, weight, and lifespan are not specified in the available records. Biological traits of this species remain poorly documented in the scientific literature. Its Least Concern status indicates that populations are currently stable within its northern South American range.
