E. lutris is highly adapted to the cold coastal waters of the North Pacific Ocean and Bering Sea, with adaptations as the large body size and forages actively (Estes 1989). Fun Facts for Kids. In the 1970s, a scientist named Dr. James Estes recognized that he could study the influence of sea otters on other species in their environment by comparing the coastal habitats in Alaska’s Aleutian Islands where sea otters had recovered to similar places where sea otters were absent. Sea otters live in a cold ocean environment and rely on two traits to keep warm: a dense fur coat for insulation and very high metabolism to generate body heat. A keystone species is one that is comparatively rare but has a strong influence on its environment. Peste 4500 modele de incaltaminte si genti. With the cost-effective capabilities of having a USV as a communication relay and support platform on the sea-surface, underwater Remotely Operated Vehicles (ROV) and Autonomous Underwater Vehicle (AUV) operations can be made possible, The Otter can carry a variety of customer defined sensors for seabed and environmental mapping. Habitat: Otters are voracious fish eaters, with fish making up over 80% of their diet, so they have evolved to live in a variety of habitats where fish are plentiful. There are 13 extant species of otter around the world, one of which is native to the UK. Size. Lontra weiri-Wikipedia. The weight of a Marine otter can vary from being 3kg or 5kg.

Their appetite for these invertebrate species exerts a strong influence on prey size and number and how they live and move in their habitat. One of the results of Dr. Estes’ research was to designate sea otters as a “keystone species”. Size: The Otter is also easily separated into parts for smoother transport. Two species are marine; the others live mostly in fresh water. Fragmentation and recovery from fur trade hunting created opportunity for scientific study. The weight of a Marine otter can vary from being 3kg or 5kg. One way that otters can counteract this is by having higher metabolic rates than land mammals of a similar size. They have a body length between 50 and 79 cms (20 - 31 inches), a tail length between 30 and 36 cms (12 - 14 inches) and they weigh between 3 and 5 kgs (6.6 - 11 lbs). Maturity: 2 years. However, marine otters tend to occur in exposed outer coast habitats, while river otters are often found in more protected inner waters (most live entirely in freshwater habitats). The large hind feet are broad and flipperlike. (Molina, 1782) - Marine otter Distinctive Characteristics Marine otters are very similar in appearance to freshwater otters. In contrast, Dr. Estes noticed that places with healthy sea otter populations often had healthy kelp forest habitat as well. Sea otter, (Enhydra lutris), also called great sea otter, rare, completely marine otter of the northern Pacific, usually found in kelp beds. A population that once extended continuously along the North Pacific Rim was reduced to a few small remnant colonies. This makes the Otter a turn-key bathymetric survey system for sheltered waters.

There are 13 species of otters, in seven genera, according to Integrated Taxonomic Information System (ITIS). The sea otter spends most of its time in the water but, in some locations, comes ashore to sleep or rest. The marine otter is generally brown with a paler, lighter underside and especially light throat. By controlling the size and number of sea urchins (sea urchins are one of their favorite foods, and they eat the larger ones first), sea otters created the opportunity for kelp to grow and flourish, which in turn created habitat for numerous other kelp forest dwellers. The Sea Otter is the only true marine otter of all the otter and they can dive up to 40metres to catch their prey. Journal of Mammalogy 89:575-581.
