藍鯨

蓝鲸是地球上已知存在过的最大动物，体长可达33米，体重达200吨，其心脏单独就重达一辆小型轿车的重量。分布于各大洋，在极地觅食地和热带繁殖地之间进行迁徙。它们是滤食性动物，每日可消耗多达4吨磷虾。蓝鲸被列为濒危物种，20世纪捕鲸活动使其濒临灭绝，目前全球种群估计约为1万至2.5万头。

克氏扇尾鹟

Cockerell's fantail (Rhipidura cockerelli) is a lively, medium-sized flycatcher in the family Rhipiduridae, endemic to the Solomon Islands archipelago in the southwestern Pacific Ocean. Like other fantails, it is characterised by its habit of fanning and cocking its long tail while foraging aerially and among vegetation for small flying insects and other arthropods. The species occupies primary and mature secondary lowland and hill forest on several islands within the Solomon group, where it typically inhabits the middle and lower forest strata, often joining mixed-species foraging flocks. Males and females are similarly plumaged in shades of rufous, brown, and black, with the distinctive white brow stripe common to many Solomon Islands fantails. Rhipidura cockerelli is classified as Least Concern by the IUCN, reflecting adequate forest cover across much of its range and the relative remoteness of many of the islands it inhabits. However, growing pressure from logging, agricultural conversion, and human settlement in the Solomon Islands poses potential longer-term risks to forest-dependent species like this fantail. The species has no presence in Norway; database listings to that effect represent a data artifact. Its distribution is confined entirely to the Solomon Islands chain. The species was named after the British entomologist and naturalist T.D.A. Cockerell, who contributed extensively to natural history collections from the Pacific during the late nineteenth and early twentieth centuries.
