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。

Christmas-bells

Christmas bells (Blandfordia grandiflora) is a perennial herbaceous plant in the family Blandfordiaceae, endemic to eastern Australia. It is one of four species in the genus Blandfordia, all restricted to Australia, and is perhaps the most widely recognized, flowering during the summer months of the Southern Hemisphere, which correspond to the Christmas season. The species produces striking pendulous, bell-shaped flowers in red and yellow, borne on upright stems emerging from tufted grass-like leaves. It grows primarily in coastal and near-coastal heathlands and wet sedgelands of New South Wales and southern Queensland, favoring waterlogged, nutrient-poor soils. Christmas bells are adapted to fire-prone ecosystems and often flower most prolifically following fire events that stimulate regeneration. The flowers are visited by honeyeaters and other nectarivorous birds, which serve as pollinators. Historically, Christmas bells were widely collected as cut flowers, and this exploitation significantly reduced some populations. Today, the species is protected under New South Wales legislation, and collection from the wild is prohibited. Habitat loss from urban expansion and altered hydrology also affects populations. The plant has cultural significance in Australia as a symbol of the summer Christmas season.
