Sea otters typically remain in the same area for years and males have larger home ranges than females.
Sea otters are long-lived and typically remain in the same area for years. An otter’s den is called a holt or couch.
Male sea otters have larger home ranges than females. The home range of a male may overlap with that of several females. Many males actively defend their territories. Disputes are usually settled with splashing and vocal displays, and fighting is rare.
Same-sex territories do not overlap and are defended by their owners.
