座头鲸(学名:Megaptera novaeangliae)又名大翅鲸驼背鲸巨臂鲸,俗称海崎(闽南语),属于须鲸亚目的海洋哺乳动物。其名「座头」之名源于日文「座头」(ザトウ),意为「琵琶」,是指鲸鱼背部的形状。该物种为大型鲸鱼:成年鲸身长可达约11.5至16公尺之间(39至52英尺),刚出生的仔鲸长约3至6公尺,目前最大的雌性标本身长将近19公尺(62英尺),胸鳍长达6公尺(20英尺);然而根据捕鲸者描述,座头鲸最大的纪录全长近27公尺(88英尺),体重接近90吨。成年鲸体重25至30吨,最重可达40吨,新生仔鲸重1至2吨。座头鲸以其跃出水面姿势、超长的前翅与复杂的叫声而闻名。全世界各大海洋都有座头鲸的踪迹,是赏鲸者的最爱之一。由于数量极为稀少,已列入《濒危野生动植物种国际贸易公约》附录。

The humpback whale (Megaptera novaeangliae) is a species of baleen whale. One of the larger rorqual species, adults range in length from 12–16 m (39–52 ft) and weigh about 36,000 kg (79,000 lb). The humpback has a distinctive body shape, with long pectoral fins and a knobbly head. It is known for breaching and other distinctive surface behaviors, making it popular with whale watchers. Males produce a complex song lasting 10 to 20 minutes, which they repeat for hours at a time. Its purpose is not clear, though it may have a role in mating.
