Habitat

Typically found in diverse terrestrial and aquatic ecosystems.

Range

Found across Europe (5 countries) and North America (United States).

Buckelwal

혹등고래는 대형 고래 중 가장 활발한 곡예를 선보이는 종으로, 번식기에 수컷이 부르는 복잡하고 신비로운 노래로 유명합니다. 일부는 몇 시간씩 지속되며 시간이 지남에 따라 진화합니다. 체장 16미터, 체중 30톤에 달하며 포유류 중 가장 긴 이주를 수행합니다. 모든 대양에서 발견되며 크릴과 작은 물고기를 협동 거품그물 먹이 방식으로 포식합니다. 과거 포경으로 크게 감소했던 개체군이 대부분 회복되었습니다.

common shrew

<em>Sorex araneus</em>, the common shrew, is a small insectivorous mammal in the family Soricidae, order Eulipotyphla, widely distributed across Europe and portions of the United States and Russia. This species inhabits a broad range of terrestrial environments including woodland, grassland, scrubland, hedgerows, and suburban gardens, typically favoring areas with dense ground cover providing both shelter and hunting opportunities. <em>Sorex araneus</em> is among the smallest mammals, with an exceptionally high metabolic rate that necessitates nearly continuous feeding to survive — it must consume close to its own body weight in food each day. Its diet consists primarily of invertebrates including earthworms, beetles, spiders, and other small arthropods found in leaf litter and soil. The species is listed as Least Concern by the IUCN, with large and stable populations across its range. Biological traits for this species remain poorly documented in the scientific literature in terms of precise standardized averages for lifespan, body length, and weight across populations, though it is known to be a short-lived species with typical wild lifespans of around one year, and is widely studied as a model organism in ecological and physiological research.
