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.

cobweb spiders

The southern black widow (Latrodectus mactans) is one of North America's most recognizable and medically significant spiders, a member of the genus Latrodectus within the family Theridiidae. Females are glossy black with the iconic red hourglass marking on the underside of the abdomen, and reach approximately 8–15 millimeters in body length; males are smaller, paler, and largely harmless. The species constructs irregular, low-lying cobwebs in dark, sheltered locations including woodpiles, outbuildings, hollow logs, rock piles, and debris, where it waits for prey—primarily insects—to blunder into the sticky tangle. Distribution spans the southeastern United States westward through Texas and northward into more temperate zones, with range overlap with related widow species. The venom of Latrodectus mactans contains alpha-latrotoxin, a potent neurotoxin that triggers massive release of neurotransmitters at synaptic junctions, causing the syndrome of latrodectism: severe muscle cramps, pain, hypertension, and autonomic disturbances. Despite its fearsome reputation, bites are rarely fatal in healthy adults when medical treatment is available. Females are cannibalistic toward males, though this behavior is less consistent in nature than laboratory conditions suggest. The species plays an important ecological role in controlling insect populations in arid and semi-arid habitats. Its conservation status has not been formally evaluated by the IUCN.
