Gray Seal Halichoerus grypus
The gray seal has a distinctive convex muzzle, which gives it a “Roman-nosed” appearance. Adults vary in color: male gray seals are usually gray overall, with pale patches on their undersides, while females often have a marbled pattern of dark patches over a much lighter background. Male gray seals may be two or three times heavier than females—a difference exceeded by few other true seals. When not hunting for their usual diet of fish, gray seals spend their time either resting on rocks or “bottling”—sleeping in the water with their bodies vertical and their nostrils just above the surface. They breed onshore, hauling themselves out onto beaches or grass farther inland. Gray seal pups have a white natal coat, and they stay onshore for two to three months before venturing into the sea.
