Sea lions do not mate for life. Females often mate with the male who is holding the breeding territory, where they give birth. She also may seek out another male she prefers. She can mate with more than one male in a breeding season. Dominant males that hold breeding territories typically mate with up to 40 females each breeding season. In subsequent seasons, other males may hold the territories. Males can grow up to about 1000 pounds; they reach full size after about 10 years.

Under the Marine Mammal Protection Act of 1972 (MMPA), coastal Alaska Natives living along the North Pacific or Arctic Ocean are the only people who may harvest sea otters. When the act was passed, Congress recognized the cultural importance of marine mammals to Alaska Native peoples, and included an Alaska Native exemption for their take for subsistence or handicraft, provided that marine mammals are not taken in a wasteful manner.

Males are sexually mature when they are about four to five years old, females when they are three to four years old. Males however, may not mate until they are 8-10 years old; when they are fully grown, more experienced, and can hold a breeding territory. See similar questions...

Through body contact, nosing one another, head-jerking and vocalizations. Sea otters, in comparison to sea lions, for example, are not extremely vocal animals. However, adults use a soft, low cooing sound, and grunts to exhibit "contentedness," among other things. Pups use a high-pitch squeal to communicate with their mom. Some other sounds in the vocal repertoire of sea otters include whistles, whimpers, squeaks, whines, growls, snarls and hisses. See similar questions...

All sea otters in the United States are classified as "depleted" under the federal Marine Mammal Protection Act. The California sea otter is also listed under state law as a "fully protected mammal." See similar questions...

Abalone, squid, snails and other molluscs; clams; mussels; crabs; lobster; urchins; sea stars; sea cucumbers; chitons; marine worms; and about 40 other marine invertebrates; and on occasion, marine birds; and in Alaska, certain fish. See similar questions...

Sea otters generally do not spend more than two or three minutes diving for food. They use their sensitive paws, whiskers and vision to make their way through the water to find food. Sea otters then return to the surface with their prey, lie on their backs, place the food on their chests and break open the prey using a tool of some kind (rock, bottle, etc.).

Sea otters are considered to be "opportunistic feeders" – that is, they feed on many prey items. They are carnivores, and, at times, omnivorous, meaning they feed on both animal and plant food. They are the top-end predator in the nearshore marine ecosystem. See similar questions...

Great white sharks are the primary predator in California. Ongoing studies in Alaska recently revealed that orcas (killer whales) are eating more and more sea otters in that region, possibly because the usual prey (seals and sea lions) are in decline. Other factors that may be influencing the orcas to eat more sea otters may include natural disturbances to the ecosystem that occur over space and time, as well as overfishing.

Sea otters have three basic ways to escape predators: fleeing; taking refuge in the kelp where they live; and coming up on land. They also have strong teeth they can use in interactions with other sea otters. See similar questions...

California sea otters average 4 feet in length and 50-60 pounds in weight. Northern sea otters are slightly larger. See similar questions...

There are no U.S. Federal government restrictions on the taking of sea otters for coastal Alaska Native subsistence as long as such practices do not contribute to the demise of the species. However, any Alaska Native Tribal Government has the ability to develop regulations on when and where hunts may occur. It is important to check with the local Tribal government to see if any regulations exist. See similar questions...

More or less. In general, it appears that they do. Unless a mate is killed or severely incapacitated, crows appear to stay with the same mate year after year. It is possible, however, for exceptions to occur. Generally this would happen in the case of a young pair of birds that mated but bred unsuccessfully. They might break the pair bond and try again with someone else. I had one young male return home after an unsuccessful first nesting attempt. See similar questions...

No. Black bear males and females come together only during breeding season. A female may mate with several males during a short estrus period and cubs from the same litter may have different fathers. See similar questions...

Peregrines generally do keep the same mate from year to year. However, if a member of the pair dies, the surviving falcon will accept a replacement mate sometimes as soon as a week after its mate died.

Red kites usually take the same mate year after year, but ‘divorces’ aren’t unheard of! The pair perform high circling displays, particularly in the early part of the day. They may pass close together, twisting apart at the last moment, and will sometimes pass food between them. Very occasionally, they may lock talons, but this behaviour is not commonly reported.

Sea otters generally give birth to one pup a year. If they give birth to two, they will abandon one of them, as they can't care for two at a time. This is how pups are orphaned. Orphans rescued by trained wildlife rehabilitators can survive to adulthood and, in fact, all three otters at the Monterey Bay Aquarium were orphans. Otters are full-grown at about 3 years of age and generally they are weaned between 6 months and 1 year of age. See similar questions...

The southern sea otter is listed as "threatened." If the population decline continues, this listing could be changed to "endangered." The northern sea otter, which consists of sub-populations in Alaska, Canada and Washington, isn’t listed as a whole subspecies. The different sub-populations have different status classifications. Currently there is no federal or state Endangered Species Act listing for Alaska and Washington. See similar questions...

Sea otters are wild animals, which means their behavior towards humans can be unpredictable. Like people and other animals, they all have individual personalities. Some may be aggressive towards humans and other otters may be friendly. There have been occasional reports of sea otters messing around with divers (e.g., pulling at their dive caps and other things). See similar questions...
