白头海雕

白头海雕是美国国鸟，也是美国生态保护史上的成功案例，曾因滴滴涕（DDT）的广泛使用而濒临灭绝，经保护措施的实施后种群数量已显著恢复。该物种在IUCN红色名录中被评估为无危（LC），以白色头颈和尾羽与深棕色体羽形成的鲜明对比为主要识别特征。它们主要以鱼类为食，也会捕食哺乳动物和腐肉。

clawed calamary squid

The Clawed Calamary Squid, Abraliopsis hoylei, is a small oceanic cephalopod in the family Enoploteuthidae found in tropical and subtropical waters of the Indo-Pacific Ocean. Like other members of the genus Abraliopsis, it is a mesopelagic to bathypelagic squid that undertakes diel vertical migrations, descending to deeper waters during the day and ascending into the epipelagic zone at night to feed. The common name refers to the robust, hook-like modifications on the suckers of the tentacular clubs, which function as grasping claws to secure prey. Abraliopsis hoylei has a streamlined, torpedo-shaped mantle with well-developed fins and large, highly developed eyes adapted for vision in low-light conditions. It is bioluminescent, producing light through photophores distributed across the ventral surface of the mantle, arms, and head, which may serve in counterillumination camouflage or intraspecific communication. The species feeds primarily on small fish, crustaceans, and other squids. It is itself consumed by a wide variety of predators including tunas, billfishes, dolphins, and seabirds. Clawed Calamary Squids have a short lifespan, probably less than one year, with rapid growth and early sexual maturity typical of oceanic squids. The species has not been formally assessed by IUCN.
