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.

Cigar shark

The cigar shark, also known as the cookiecutter shark (Isistius brasiliensis), is a small but remarkable shark in the family Dalatiidae, found throughout warm oceanic waters worldwide in tropical and subtropical latitudes. Reaching only 40–50 centimeters in length, it possesses oversized jaws with large, triangular lower teeth arranged in a saw-like series that cut distinctive circular plugs of flesh from much larger prey—including tuna, dolphins, whales, billfish, and even submarine cables and human bodies. It does not kill its prey but instead latches on, rotates its body, and excises a characteristic cookie-cutter-shaped bite. The cigar shark is bioluminescent, emitting a green glow from photophores on its ventral surface that may serve as counter-illumination or to attract prey from below. It undertakes diel vertical migrations, ascending to shallower waters at night and descending to mesopelagic depths during the day. The species is classified as Least Concern by the IUCN, with a vast oceanic distribution and no targeted commercial fishery. It is occasionally taken as bycatch. The geographic epithet brasiliensis refers to Brazil, where early specimens were described, but the species' range is circumglobal in warm oceans. The cookiecutter shark's feeding strategy is one of the most unusual among elasmobranchs.
