流行观点认为女性把更多脂肪储存在腰以下,是为怀孕和哺乳提供脂肪储存。
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.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。
Since such a large proportion of their fat stores is exhausted despite feeding, mother seals clearly cannot support all of lactation using only energy stored before giving birth.由于如此大比例的脂肪储备在喂养过程中会消耗殆尽,海豹母亲显然不能仅靠生育前储存的能量来维持整个哺乳过程。
