Summary Harbor seals are an important apex predator, feeding on a diverse range of fish and invertebrates in nearshore waters including herrings, sardines, hake, flounder, sole, octopus, squid and crabs. Harbor seals spend about half of their time hauled out resting, sunning, reproduction, and interacting socially. Haul-outs can be in any coastal habitat and are locations suitable for assessing seal populations and role of local and regional disturbance in seal abundance. General Information Sustainability Goal Goal 5. Protect and enhance environmental conditions by improving watershed, floodplain, and aquatic condition and processes.
