(17) Dissections and manipulations of the hands of 14 specimens of four genera of fur seals and sea lions and of generalized fissiped carnivores were used to identify the structural modifications involved in formation of the expanded forelimb paddles characteristic of these pinnipeds.
(18) Unique features of forelimb function during swimming in these pinnipeds include the amounts of abduction-adduction and rotary movements used.
(19) In contrast, in the lipoproteins of pinnipeds (harbor seals, sea lions, and walrus) there was no protein comparable in size to human apoE; however, there were two proteins in the 40- to 44-kDa range.

Superfamily
Definition:
(n.) A group intermediate between a family and a suborder.
Example Sentences:

(7) The rodent, avian, and insect L1-like cell adhesion molecules are members of the immunoglobulin superfamily that have been implicated in axon growth.
(8) This superfamily of proteins is predicted to share the topology of the seven transmembrane helices of bacteriorhodopsin (BR), even though no significant sequence homology had been identified.
(9) Other members of an alpha 2-microglobulin superfamily bind and transport hydrophobic ligands.
(10) As suggested from the high level of sequence similarity of these viral proteins with the recently described superfamilies of helicase-like proteins (3-5), the NTBM-containing cylindrical inclusion (CI) protein from plum pox virus (PPV), which belongs to the potyvirus group of positive strand RNA viruses, is shown to be able to unwind RNA duplexes.
