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。

Chufa (Edible Variety)

Chufa, also known as Tiger Nut or Earth Almond (Cyperus esculentus), is a cosmopolitan sedge in the family Cyperaceae valued for the edible, starchy tubers produced on its underground stolons. Originating in Africa, it was cultivated by ancient Egyptians and has spread to virtually all inhabited continents, thriving in warm to temperate regions with sufficient moisture. In Spain, chufa is commercially grown in Valencia for the production of horchata de chufa, a traditional sweet, milky non-dairy beverage made from soaked and ground tubers. The plant grows 20–90 cm tall with triangular stems characteristic of sedges, producing dense, grass-like foliage and small umbrella-shaped floral clusters. The pea-sized tubers are high in starch, sugars, fat, and dietary fiber. While valued as a food crop in some regions, Cyperus esculentus is considered an invasive weed in many agricultural contexts, particularly in maize, soybean, and sugar cane fields worldwide, where its deeply buried tubers make eradication difficult. The species is listed as Not Evaluated by the IUCN. Its global distribution and weedy habits make population-level threats essentially irrelevant in the conventional conservation sense.
