Lobe-Toothed Seals in GURPS

Lobe-toothed seals are Antarctic seals. They have unique molar teeth, with projections out the sides to allow their half-closed mouths to act as sieves. They use these structures to gulp up krill, which exist in huge numbers in the Antarctic waters, and then keep the krill while expelling the water. Like other earless seals, they swim with up-and-down undulating motions using their back flippers for propulsion and their front flippers for steering. On land, most of them caterpillar-hump to get about, although crabeaters slither.
