Click beetle

Click Beetle 2 represents another species among the over 10,000 members of the family Elateridae, sharing the family's characteristic body plan and the distinctive clicking mechanism used for self-righting. Elaterid beetles occupy a wide range of ecological niches from soil-dwelling larvae that consume roots and decaying wood to adults that visit flowers or feed on fungal tissue. The specific species referred to by this entry may belong to any of numerous genera within the family, each adapted to particular habitats and host resources. In tropical regions, click beetles include brightly luminescent species in the genera Pyrophorus and Ignelater, which produce bioluminescent light from paired spots on the thorax to attract mates. In temperate regions, economically important wireworm species of genera Agriotes and Melanotus are significant pests of agricultural crops. Some click beetle larvae are predatory, feeding on wood-boring beetle larvae and other soil invertebrates. The diversity of ecological strategies within Elateridae makes them important components of both forest and agricultural ecosystems. Conservation status depends entirely on the specific taxon in question; the majority of click beetle species have not been formally assessed.

Polar bear

北极熊是地球上最大的陆地食肉动物，体重可超过700千克，分布于从加拿大到俄罗斯的北极海冰区。是高度特化的海洋哺乳动物，依赖海冰捕猎环斑海豹和髯海豹。是优秀的游泳者，能够横渡广阔的开阔水域。被列为易危种，因气候变化导致北极海冰迅速减少，种群正受到严重威胁。
