The main differences in fatty acid composition of blubber between the Saimaa seal (Phoca hispida saimensis) and the Baltic seals (Phoca hispida botnica and Halichoerus grypus) were, that in fresh water the proportions of polyunsaturated C18 acids and arachidonic acid (20:4 omega 6) were high. 2. The trend became more evident when data on ringed seals from northern oceans were compared with the present data. 3. The proportions of exogenous 20:1 and 22:1 were extremely low in ringed seals from Lake Saimaa and in Baltic seals compared with seals living in oceans.

塞马湖海豹（Phoca hispida saimensis）与波罗的海海豹（Phoca hispida botnica和Halichoerus grypus）皮下脂肪的脂肪酸组成主要差异在于，在淡水中，多不饱和C18酸和花生四烯酸（20:4 ω6）的比例较高。2. 当将北冰洋环斑海豹的数据与当前数据进行比较时，这种趋势变得更加明显。3. 与生活在海洋中的海豹相比，塞马湖环斑海豹和波罗的海海豹中外源20:1和22:1的比例极低。
