All existing sea otter, Enhydra lutris, populations have suffered at least one historic population bottleneck stemming from the fur trade extirpations of the eighteenth and nineteenth centuries. We examined genetic variation, gene flow, and population structure at five microsatellite loci in samples from five pre-fur trade populations throughout the sea otter's.

You will find out the very interesting sea otter from their background to the diet and habitat of the sea otter. Sea otters have an amazing background here you will find out a thing or two about sea otters.Sea otter males can weigh over 70 pounds. A female can be at least 40 pounds or less. (“Sea Otter Facts”,n.d.). Sea otters are a marine species of otter, as hinted by their telling names! They live along the coast of the Pacific Ocean in Asia and North America. They can weigh up to 99 pounds, making them the heaviest otter species. They have various adaptations that help them thrive in their unique aquatic environment. Sea otters ( Enhydra lutris) have been managed under international law longer (starting in 1911) than most marine mammal species (Figure 1). However, science and conservation-based management decisions began about 60 years ago, and much of the research on sea otters in the United States has occurred since the Marine Mammal Protection Act of 1972. Size: 2 to 6 feet long. Weight: 10 to 75 pounds. The charismatic otter, a member of the weasel family, is found on every continent except Australia and Antarctica. Most are small, with short ears.

Adaptions ! The sea otter has made many adaptations in order to survive better in its habitat. First, the sea otter uses their feet to reduce or maximize heat loss when water temperatures are too hot or too cold. When the water temperatures are too cold sea otters reduce heat loss by floating on their backs with their feet out of the water.

How do sea otters help climate change? With the protection sea otters provide these forests flourish. Kelp forests that are guarded by sea otters can sequester up to 12 times more carbon from the environment. Researchers have found that the presence of sea otters increases kelp forest carbon storage from 4.4 to 8.7 megatons annually.

Sea Otter's Natural Habitat. Sea otters are shallow coastal water dwellers, as it is easier to adapt to. They live the majority of their lives on the ocean surface in areas where water is less than 130 ft deep. Here they eat, reproduce, rest, or do any other social interactions. The other small part of their lives live on the ocean floor to.

Abstract. Despite its recent invasion into the marine realm, the sea otter (Enhydra lutris) has evolved a suite of adaptations for life in cold coastal waters, including limb modifications and dense insulating fur.This uniquely dense coat led to the near-extinction of sea otters during the 18th-20th century fur trade and an extreme population bottleneck.

One physiological phenomenon in river otters that may in part be a winter adaptation, is delayed implantation of embryos. This is also called embryonic diapause. Mating takes place in early spring, but embryos remain dormant and free floating in the uterus for 8-9 months, before attaching and developing.

Adaptions ! The sea otter has made many adaptations in order to survive better in its habitat. First, the sea otter uses their feet to reduce or maximize heat loss when water temperatures are too hot or too cold. When the water temperatures are too cold sea otters reduce heat loss by floating on their backs with their feet out of the water.

Sea otters have a symbiotic relationship with kelp forests. The animals often wrap themselves in kelp so they do not drift away in the ocean's swirling currents. They also rely on kelp to provide them cover from predators, and a habitat for the animals they hunt. Sea otters eat urchins and other invertebrates that graze on kelp.

Habitat. Sea otters inhabit temperate coastal waters with rocky or soft sediment ocean bottom. They live in offshore forests of giant kelp (Macrocystis pyrifera), and spend most of their active time foraging below the canopy. They eat, rest, and groom themselves at the water surface. While sea otters are capable of diving to depths of at least. Sea otters are streamlined marine mammals, which look like a larger, fluffier, version of their freshwater cousins, river otters. They have four legs to move easily on land, and a long tail to swim through the water. Sea otters also have thick, brown fur that insulates them against the cold waters of the Pacific Ocean.

Habitat. Otters are usually found no more than a few hundred meters from water. Most species are entirely dependent on aquatic habitats for food. River otters (genus Lutra) inhabit all types of inland waterways, as well as estuaries and marine coves. In southern Chile the marine otter is found almost exclusively along exposed rocky seashores.

An otter’s fur is thick, containing about 156,000 hairs per square inch, creating almost a waterproof seal over the animal’s body that insulates it in the water.

The hind feet, which provide most of its propulsion in swimming, are long, broadly flattened, and fully webbed. The fifth digit on each hind foot is longest, facilitating swimming while on its back, but making walking difficult. A sea otter typically eats 3-4 times per day. Locating food occurs on the bottom of the sea floor. Otters can be found feeding in small groups. Their whiskers are used to sense and find small creatures hiding in the dense kelp beds. Small, swift forepaws help capture prey and allow the otter to manipulate their prey in various way such as.

. Despite its recent invasion into the marine realm, the sea otter (Enhydra lutris) has evolved a suite of adaptations for life in cold coastal waters, including limb modifications and dense insulating fur.This uniquely dense coat led to the near-extinction of sea otters during the 18th–20th century fur trade and an extreme population bottleneck.

Eurasian Otters' Habitat and Distribution. Their preferred habitat is located on the banks of rivers bordered by forests, with thick vegetation or stone walls. They also like crystal clear waters with stony bottoms. The male's territory can cover about 15 km of river, crossing it every 3 or 4 nights. Two times the genetic diversity was found in the pre-fur trade populations when compared to modern sea otters, a level of diversity that was similar to levels that are found in other mammal populations that have not experienced population bottlenecks. All existing sea otter, Enhydra lutris, populations have suffered at least one historic population bottleneck. Sea otters are vulnerable to oil spills which can drastically impact the insulating power of their fur, and destruction of kelp forests which are key foraging grounds. They are also preyed upon in the wild by sharks, bears, eagles and killer whales. In this chapter, we review the morphologic, physiologic, and sensory adaptations that influence sea otter behavior . Previous studies have identified five distinct behavioral activities in sea otters: resting, foraging, transiting, grooming, and socializing/mating (Figs. 3.1 and 3.2 ; Kenyon 1969 ; Garshelis 1983 Thometz et al. 2014 ; Cortez et al. 2016a ).

River otters rest and lounge on dry land and swim belly down. Sea otters spend nearly all of their time in the water. They often float on their backs, even eating and napping this way. One of the adaptations the sea otter has developed is its habit of holding hands with its companions while napping. This keeps the partners from drifting apart.

Adaptions ! The sea otter has made many adaptations in order to survive better in its habitat. First, the sea otter uses their feet to reduce or maximize heat loss when water temperatures are too hot or too cold. When the water temperatures are too cold sea otters reduce heat loss by floating on their backs with their feet out of the water.
