Canadian beaver

북아메리카에서 가장 큰 설치류인 캐나다비버는 체중이 최대 32kg에 달하며 캐나다 및 미국 북부의 강, 호수, 습지에 서식하는 생태계 공학자의 대가입니다. 나무를 베고 수백 미터에 달하는 댐을 건설하여 수백 종에게 서식지를 제공하는 연못을 만들어냅니다. 이들의 보금자리와 수로는 유역 전체를 변화시킵니다. 한때 모피를 위한 남획으로 거의 멸종 위기에 처했으나, 비버 개체군은 강하게 회복되었습니다.

Collared Worm Salamander

The Collared Worm Salamander, known scientifically as <em>Oedipina collaris</em>, is a slender, elongated salamander belonging to the family Plethodontidae, the lungless salamanders. <em>Oedipina collaris</em> is characterised by its worm-like body form, extremely elongated trunk with many vertebrae, short limbs, and a long tail — morphological features that adapt the species for a burrowing or semi-fossorial lifestyle. As a plethodontid salamander, <em>Oedipina collaris</em> lacks lungs and respires entirely through its moist skin, making it highly dependent on humid environments. The species inhabits freshwater habitats, moist forests, and wetlands. Detailed biological traits including typical lifespan, body length, and weight are poorly documented for this species in available literature. The Collared Worm Salamander is currently assessed as Data Deficient on the IUCN Red List, indicating that insufficient information is available to determine its conservation status accurately, and further research on the species' distribution and population trends is required.
