大翅鯨

座头鲸是大型鲸类中最具杂技表演性的物种之一，以繁殖季节雄性演唱的复杂而神秘的歌声著称，歌声有时持续数小时并随时间演变。体长可达16米，体重30吨，进行着哺乳动物中最长距离的洄游。分布于所有大洋，通过协作泡泡网捕食磷虾和小鱼。种群数量已从历史捕鲸后大体恢复。

clear glass snail

The Clear Glass Snail is a common name applied to small, translucent land snails, typically in the family Vitrinidae or Zonitidae, characterized by their thin, glassy shells through which the soft body of the animal is often visible. These snails inhabit moist, shaded environments including deciduous woodland, grassland with thick vegetation, and hedgerows across Europe and North America. The thin, transparent shell is often not large enough to completely retract into, leaving the mantle partially exposed, an adaptation that reduces shell weight while maximizing the internal surface area available for gas exchange. Clear glass snails are detritivores and microphages, consuming fungi, algae, decaying plant matter, and occasionally living plant tissue. They are sensitive to desiccation and are most active during wet, cool conditions, retreating under bark, stones, or into leaf litter during dry weather. Several European glass snail species are considered indicators of old, undisturbed woodland habitats with stable microclimatic conditions. Some species in the family Zonitidae have declined due to loss of old woodland, intensive agriculture, and fragmentation of semi-natural habitats. Exact conservation status depends on the specific species intended by the common name.
