PC abundance in odontocetes versus pinnipeds. The abundance of A) chromatographically separated PC species and B) grouped PC species – PCs 16:0/16:0 + 16:0/16:1 + 16:0/14:0 and PCs 16:0/16:1 + 16:0/14:0 – are compared between odontocetes (common dolphin and harbor porpoise) and pinnipeds (harp seal and California sea lion). PC 18:0/18:1 co-eluted with PC 16:0/20:1 in harp seal, harbor porpoise, and dolphin but was undetermined in CSL. Error bars represent standard deviation of the mean. Harbor porpoise and California sea lion included samples frozen prior to surfactant isolation.
