港海豹,学名Phoca vitulina (Linnaeus, 1758年),是海豹科海豹属的一种海豹。是分布在北半球温带及极地海域的海豹。它们出没于大西洋及太平洋的海岸水域,与波罗的海及北海,是分布最广的鳍足类。肉食性,它们猎食鱼类、乌贼和节肢动物,如鲱鱼、鳀科、鲈鱼、鲱鱼、鳕鱼、牙鳕等。港海豹全球数量约为40~50万只,某些地区的亚种正在濒危。捕猎海豹现已全面禁止。
虽然港海豹的体型较小,但其体型与大多数的 otariids(海狮和海狗)相似。
Though smaller than many other phocids, harbor seals are similar in size to most otariids.
已经有一些证据表明环斑海豹,即一种体型与港海豹相似的海豹科物种,可能也会使用母性觅食策略。
There is already some evidence suggesting that the ringed seal, a phocids species that is similar in size to the harbor seal, may also use a maternal foraging strategy.
与其他 phocids 物种(如灰海豹)相比,港海豹体型较小。众所周知,灰海豹在整个哺乳期都禁食。
Harbor seals are small compared with other phocids species such as grey seals, all of which are known to fast for the entire lactation period.
