Phocid seal species show great diversity in the behaviors that have evolved to overcome these challenges. Although all phocids forage in marine

Seals spend an extended period of time foraging far from the breeding colony, building up their energy reserves for a relatively brief pupping season onshore where access to food is limited. During lactation, enormous amounts of energy are quickly transferred from mother

Harbor seals haul out on many types of coastal or ice environments where they engage principally in resting but also come ashore for pupping and nursing, temperature maintenance, predator avoidance, digestion, and molting. Males may defend underwater territories near haulout
