    The Phocidae can be divided into two subfamilies—the Monachinae, consisting of the southern phocids, the southern ( Mirounga leonine) and northern elephant seals ( M. angustirostris) and the monk seals and the Phocinae, or northern seals ( Table 1 ).
    In crab-eating seals, for example, the cheek teeth have complex cusps that make them into sort of a sieve, used for straining plankton. Most seals feed on fish, squid, octopus, and shellfish, but some take plankton, and one species catches penguins and small seals. The social structure of phocids varies from species to species.

    Most phocids are pierced feeders with a few taxa having developed specialized strategies (e.g., grip and tear feeding in leopard seals, filter-feeding in the crabeater seal and possibly the fossil phocid Homiphoca, and suction feeding in elephant, bearded, and hooded seals).
    Adult phocids vary from 1.17 m (3.8 ft) in length and 45 kg (99 lb) in weight in the ringed seal to 5.8 m (19 ft) and 4,000 kg (8,800 lb) in the southern elephant seal, which is the largest member of the order Carnivora. Phocids have fewer teeth than land-based members of the Carnivora, although they retain powerful canines.
