Common Sunda Toad

<em>Duttaphrynus melanostictus</em>, the common Sunda toad, is an amphibian in the family Bufonidae, order Anura. It has a wide natural distribution across South and Southeast Asia, ranging from Pakistan and India through to southern China, the Malay Peninsula, and the Indonesian archipelago, and has also been introduced to Madagascar. The species typically inhabits a broad range of environments including urban areas, agricultural land, forest edges, gardens, and disturbed habitats, demonstrating remarkable adaptability to human-modified landscapes. <em>Duttaphrynus melanostictus</em> is characterized by prominent parotoid glands behind the eyes that secrete toxic compounds serving as a defense against predators, a feature shared with other true toads. It is an opportunistic carnivore, feeding on a variety of invertebrates including insects, worms, and small arthropods. Biological traits including average lifespan under natural conditions, typical body measurements, and specific breeding parameters remain poorly documented. The species is assessed as Least Concern by the IUCN, reflecting its extensive range and high tolerance for habitat modification, though introduced populations in Madagascar represent a potentially invasive concern.

Polar bear

지구상에서 가장 큰 육상 육식동물인 북극곰은 700kg을 넘을 수 있으며 캐나다에서 러시아까지 북극 해빙 전역에 분포한다. 고리 물범과 수염 물범을 사냥하기 위해 해빙에 의존하는 고도로 특수화된 해양 포유류이다. 광활한 거리를 헤엄쳐 다닐 수 있는 뛰어난 수영 실력을 가지고 있다. 취약종으로 등재되어 있으며, 기후 변화로 인한 급격한 북극 해빙 감소로 심각한 압력을 받고 있다.
