I appreciated the author's ability to present dense history and scientific insight clearly and cohesively; and also admired his willingness to present information (albeit more limited) about the perspectives of those who oppose expanded protections or resources for this furry little creature. However, the publication date meant the most recent history of the sea otter felt lacking. That said, I greatly enjoyed the information about the otter itself - its behaviors, its anatomy and physiology, and so on - and was pleased with the large collection of photos that capture the otter's personality and endearing appeal. http://alliance-ltd.com/userfiles/daimler-supplier-management-manual.xml Having spent time in Monterey Bay growing up, parts of this book felt like a lovely trip down memory lane.

In fact, at 850,000 to 1,000,000 hairs per square inch, they have the thickest fur of any mammal. Their fur consists of two types of hairs, interlocking underfur (which provides insulation) and longer guard hairs (that help water run off the coat). This system traps a layer of air next to their skin so, when fur is well groomed, their skin does not come in contact with sea water. Sea otters are usually dark brown, and some individuals may be progressively lighter colored (grizzled) on the head, neck, chest and forearms due to loss of pigmentation in the guard hairs. Extent of grizzle can be related to age and individual variation. Sea otters are one of the smallest marine mammals, with only their South American cousin the marine otter ( Lontra felina ) being smaller at 6-11 lbs. With a flexible skeleton, shortened forelimbs, and lack of a collar bone, sea otters are adapted to “belly-up” lifestyle. They can be distinguished from other marine mammals by their tendency to float on their backs and will use their abdomen as a table and a platform for young pups when on the surface. They can also be identified by their unique combo of paws on their forelimbs and flipper-shaped hind feet. In California adult females weigh 35-60 pounds (16-27 kg); males reach up to 90 pounds (40 kg). Alaskan sea otters are bigger with males weighing as much as 100 pounds (45 kg). In the early 1700s, the worldwide population was estimated to be between 150,000 and 300,000 individuals. Prior to large-scale commercial exploitation, indigenous people of the North Pacific hunted sea otters. Although it appears that harvests periodically led to local reductions of sea otters, the species remained abundant throughout its range until the mid-1700s. Following the arrival in Alaska of Russian explorers in 1741, extensive commercial harvest of sea otters over the next 150 years resulted in the near extirpation of the species. When sea otters were afforded protection by the International Fur Seal Treaty in 1911, probably fewer than 2,000 animals remained in 13 remnant colonies. There are currently 3 subspecies of sea otter, the northern sea otter ( Enhydra lutris kenyoni ), the Asian, or Russian, sea otter ( Enhydra lutris lutris) and our southern, or California, sea otter ( Enhydra lutris nereis ). Currently, the California population numbers around 3,000 and ranges from Half Moon Bay to Santa Barbara. Sea otters inhabit shallow coastal areas and show a preference for places with kelp. Females will often mate with a single male during estrous (sometimes more than one), especially if they form a pair bond. Pair bonds last for several days during which the male and female stay in very close proximity. During mating, males grasp the female’s nose and face with their teeth, sometimes drawing blood or leaving a persistent light-colored scar. In some parts of California, injuries to the nose incurred during mating can be severe and even life threatening. Females give birth to one pup and usually have their first pup at the age of three or four. The gestation period is 6 months on average and includes a period of delayed implantation of the embryo, thought allow the female to put on fat between the weaning of the prior pup and birth of the next. Pups can be born any time of year, but in California there is a peak in pupping between January and March. When born, the pups weigh from three to five pounds. Females devote a considerable amount of energy to pup rearing, while males provide no parental care. By the end of the pup dependency period, females may be expending twice as much energy producing milk, sharing prey, and caring for their pups as they would during periods without a pup. This can result in seriously compromised health and body condition of the female at the time of pup weaning, particularly in range center populations where sea otters are present at high densities and the food supply is limited. During this time, female sea otters may be particularly vulnerable to changes in prey abundance, aggressive males, and disease. Chronic disturbance by kayaks and other marine recreation activities may cause unnecessary depletion of energy at this critical stage of reproduction. Kelp and eelgrass often form a canopy on the ocean surface, much like trees in a forest from canopy overhead. Sea otters will gather in patches of kelp or eelgrass canopy to rest, even securing themselves by wrapping in long strands. Mothers of young pups will often leave their pups in kelp surface canopy when they dive in search of food. Bachelor males (young males, males that haven’t acquired territories, and territorial males on “breaks”) will often gather in all male rafts where they rest and spar with one another in play-like bouts that rarely result in injury. In contrast, when guarding a territory, territorial males will attempt to exclude all other males---sometimes aggressively. Pups are dependent on their mothers for the first 6-8 months of their life. The dense “natal” coat of young pups traps so much air the pup in unable to dive. When mothers leave the pups nestled in kelp to dive for prey, pups bob on the surface of the ocean like a cork. Mothers spend much time grooming pups and often carry them on their chests. Pups begin to learn to swim at around four weeks of age and lose their super buoyant natal coat at around 8-10 weeks of age, at which point they are able to dive alongside their mothers. In parts of the range where they are competing with other sea otters for food, they can become specialized in types of prey. Sea otter scientists currently recognize five different dietary specialization types: 1) Cancer -type crabs; 2) abalone; 3) mussels; 4) sea snails; and 5) clams. Sea otters are one of the few animals to use tools and will use a rock like an anvil or hammer to break open hard-shelled prey like snails and clams. Sometimes they will use the claw of a crab to break open the crab’s own shell. Contrary to popular myth, sea otters do not carry a single tool with them throughout their life and will select a new tool for each foraging bout. When sea otters are under water searching for food, they sometimes store what they have found in the loose skin folds at their armpits. In order to help stay warm while living in a cold-water environment, sea otters have very high, heat-generating metabolisms and need to eat roughly 25 of their body weight every day to stay healthy. Sea otters primarily rely on their sense of touch to locate prey, using their sensitive forepaws and whiskers to probe crevices and sea floor for invertebrates. They may feed equally during the day and at night. In a healthy, well-groomed sea otter coat, the insulating air layer prevents cold water from ever touching their skin. While grooming, sea otters may roll about, turn somersaults, scrub with their fore and hind feet, and even blow air into their coat with their mouth. Unlike other marine mammals, sea otters do not have a blubber layer. Therefore, they rely on their fur to keep warm. If their fur is oiled, it loses its insulating qualities and the sea otters soon chill. Otters are also affected by the oil fumes or poisoned by eating food exposed to oil and attempting to groom an oiled coat. Most sea otters quickly die in an oil spill. Several thousand sea otters died in the 1989 Exxon oil spill in Valdez, Alaska. The number of Southern Sea Otters killed by Great White Sharks ( Carcharodon carcharius) in California has dramatically increased to as much as 60 of known mortalities (2016) in recent years. Scientists do not fully understand the cause of this increase although they suspect that sharks only “sample” sea otters while hunting for more suitable prey like seals. At the center of the range in California (roughly Moss Landing to San Luis Obispo), the sea otter population is thought to be at or near carrying capacity. That is, the population numbers are as high as current resources levels (specifically prey) can support. Change may be in progress along the central coast, however, as abundance of sea urchins, a favorite prey of sea otters, has increased at some locations due to the loss of the large, predatory Sunflower Star ( Pycnopodia helianthoides ) to Sea Star Wasting Disease. With the sunflower stars gone, sea urchin populations skyrocket, and current research is examining how sea otters respond to this increase in availability of a nutrient rich food source. In the absence of increased prey availability at range center, further population growth can occur only through expansion at the range ends to the north and south. Sea otters are additionally protected under the Marine Mammal Protection Act. You will see otters with brightly colored tags on their hind flippers---the color combination and positioning of the tags are unique for each otter. The researchers study foraging (what the otters eat), where the otters live in the slough and harbor, and how well they reproduce and survive. During this study (which concluded in fall of 2016) researchers were out daily tracking the tagged otters from shore and boats using antennas and high-powered spotting scopes. One recent study has shown that the presence of sea otters in the slough has increased the health of the eelgrass beds that are important for overall estuary health. Tiny sea slugs keep the surface of the eelgrass clean. By feeding on a crab that in turn feeds on the sea slugs, sea otters allowed slug numbers to increase and eel grass to flourish. From bimonthly counts, we know that there are typically around 100 sea otters living in the slough and harbor, but this number fluctuates seasonally. When in this group, the males rarely fight, but instead engage in mock contests, or sparring to practice and learn skills. Males of all ages may be in this group with many only visiting part time, leaving periodically for the open Monterey Bay. Members of this bachelor group will also regularly rest on the beach curving northward inside the north jetty. This behavior, known as hauling out, is not uncommon in sea otters, but most often occurs in hidden places or darkness when sea otters feel safer. Researchers studying this behavior have found that, once out of the water, sea otters’ body temperature warms more rapidly and stays warmer longer when they are hauled out. The social interactions, proximity to food resources and haul-outs, and relative safety from shark predators make this bachelor area an important place for California’s male sea otters. During the 1990s through 2010 the number of otters inside the Bay were generally well below ten. Since 2010 the numbers have increase with most recent surveys counting more than 40 sea otters inside the protected waters of the Morro Bay Harbor. Why are there more sea otters in Morro Bay. Resources drive the need of sea otters to inhabit a specific area. Resources that are important to sea otters are food (high densities of their invertebrate prey), refuge from predators like white sharks, and safe habitat to rest and rear their offspring. Morro Bay may offer any or all of these to the sea otters living there. When the Macrocystis canopy is present at Target Rock, 20-30 sea otters may be resting in the kelp bed. At Coleman Beach, sea otters gather in groups of 2-20 in the shallow open water 10-70 meters from shore or within eelgrass beds at low tide. Sea otters often seek surface canopy of kelp or eelgrass to anchor themselves while resting singly or in groups called rafts. Canopy availability in the harbor is dependent on tide level, currents, and seasonal persistence of kelp and eelgrass, with the Target Rock ledge providing the only suitable rocky substrate needed for Macrocystis to thrive. In Morro Bay, sea otters may also rest in eel grass beds or in open water if kelp canopy is not available. When kelp canopy is absent in winter, a large raft of females with pups may gather inside the south public T-pier near the Embarcadero. Sea otters on the San Luis Obispo county coast spend between 10 and 12 hours resting or sleeping each day. Kayakers, stand-up paddlers, scuba divers, ecotour operators, and others are often unaware that the manner in which they behave near otters can cause disturbance to important behavioral patterns and result in wasted energy, increased stress, and potentially pup abandonment. Because sea otters don’t store energy in the form of fat, they are always dependent on a delicate balance of energy income (in the form of food) and energy expense (in the form of activities such as swimming back and forth to foraging areas, social interaction, fur maintenance, and care for their pups). Swimming and diving to avoid watercraft that approach too close or too aggressively results in an additional energy expense burden. If an energy deficit is the result, the sea otter must either find more prey to eat or risk losing body condition, which is elemental to good health, disease resistance, reproductive success, and survival.
