Bamboo bear

자이언트판다(Ailuropoda melanoleuca)는 중국 중부 산지 대나무 숲에 서식하는 흑백의 상징적인 곰으로, 몸무게는 최대 125kg에 달하며 하루 최대 14시간을 대나무 섭취에 소비합니다. 식육목에 속함에도 불구하고 식이의 99%가 대나무이며 대나무 줄기를 잡기 위한 위족지(의사 엄지)를 가집니다. 성공적인 보전 및 번식 프로그램 덕분에 2016년 위기(EN)에서 취약(VU)으로 하향 조정되었습니다.

common earthworm

<em>Lumbricus terrestris</em>, the common earthworm, is one of the most ecologically significant invertebrates in temperate soils and is native to Europe, with introduced populations established across North America and other regions globally. The species is not evaluated by the IUCN Red List. <em>Lumbricus terrestris</em> belongs to the family Lumbricidae and is widely distributed across Belgium, Denmark, Germany, Norway, Sweden, the United Kingdom, the United States, and other countries in its introduced range. It typically inhabits moist, organic-rich soils in gardens, agricultural fields, woodlands, and grasslands, burrowing deep into the substrate and surfacing at night or after rainfall to feed on decomposing leaf litter and soil organic matter. As a detritivore and ecosystem engineer, the common earthworm dramatically improves soil structure, aeration, drainage, and fertility through its burrowing activity and the production of nutrient-rich castings. It is a critical food source for a wide range of predators including birds, mammals, amphibians, and invertebrates. Charles Darwin extensively studied <em>Lumbricus terrestris</em> and recognized its profound role in soil formation and ecosystem functioning in his 1881 publication on the subject. Biological traits of this species remain poorly documented in the scientific literature.
