There are 13 species of otters, in seven genera, according to Integrated Taxonomic Information System (ITIS). The otter is lithe and slender with short legs, a strong neck, and a long flat tail that helps propel it gracefully through water. What Makes Otter Rock Unique Click on seafloor habitat map. Marine Otter. All Rights Reserved. The truth is, we don’t even really know what we’re missing.” -Lilian Carswell, US Fish and Wildlife Service Southern Sea Otter Recovery Coordinator, High metabolism means they control numbers of their prey species. The Otter can carry a variety of customer defined sensors for seabed and environmental mapping. So, a 50-pound otter would need to eat about 10-15 pounds of food per day. in a “marine” environment), but they are the only otter that spends most of its time in the water. Creel, S., G. Spong, and J. Sands. These beautiful species have 150,000 hairy filaments per square centimeter in their skin, which is the highest concentration in any mammal species. The Marine otter … Beneath the Surface At the north end of the marine reserve you’ll find extensive rocky intertidal habitats along the shore. IUCN Otter Specialist Group Bulletin A Review 1:7-28. The Otter is also easily, Robots helping other robots is the next frontier. With a footprint of only 200 x 108 x 81.5cm and a weight of 55 kg, it is an easily deployable asset that can be transported in a van or even within normal airliners to the survey site. Sensor and payload data can be monitored in the Vehicle Control Station. Metapopulation Dynamics and Estimation of Population Size of Marine Otter (Lontra felina) Using Molecular Markers in Chile. In the UK IOSF is the only charity solely dedicated to the conservation, protection and care of otters based on years of scientific research in the UK and around the world. Hughes discovered that sea otters were feeding on crabs that in turn were feeding on sea slugs. We report on the phylogeny of Lontra ssp. Sea otters are carnivores that feed on an array of marine species—mostly invertebrates like crabs, clams, urchins, snails and worms. The Otter™ Unmanned Surface Vehicle (USV) is an easily deployable turn-key system for seabed mapping and monitoring of sheltered waters. Sea otters have a high metabolic rate (that is, they use a high amount of energy) that is 2-3 times that of other mammals their size. There are 13 species of otters, in seven genera, according to Integrated Taxonomic Information System (ITIS). Size: Males (also known as dog otters) can reach a length of 130cm from nose to tail, while females (bitch otters) are smaller. The sea otter distinguishes itself from other marine mammals in its evolutionary strategy of extremely dense fur as opposed to blubber in order to survive in freezing ocean temperatures. The autonomous future is electric, and the Otter is equipped with electric thrusters that are powered by 4 powerful and easily interchangeable battery packs. Floating on its back, it opens mollusks by smashing them on a stone balanced on its chest. An estimate of otter population size in Alaska was 98,780 among the three populations in 2013 (USFWS, 2013) with observed annual growth rates in some areas reaching 16–20% (Bodkin et al., 1999; Estes, 1990). Size. 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. Many of the funding sources that have supported our work over the last five years are reducing or suspending funding opportunities as they ride out the pandemic. Their appetite for these invertebrate species exerts a strong influence on prey size and number and how they live and move in their habitat. Otters are carnivorous mustelids in the Lutrinae subfamily. Our vehicle has repeatedly proven itself to excel in such areas as can be seen in the example of a Water Reservoir survey conducted with Terratec AS and Norbit. Activity of L. felina is generally diurnal, with peaks of activity noted in early morning, mid-afternoon, and evenings. The Otter is equipped with electric thrusters that are powered by up to 4 powerful and easily interchangeable battery packs. The length of this otter is usually around 87 centimetres. The Sea Otter is a marine mammal native to various coastlines of the northern Pacific Ocean. The smallest river otter is the marine otter, averaging 87 to 115 cm (34-45 in. 2003. size: 87-115 cm (body 57-79 cm, tail 30-36 cm) weight: 3-6 kg The smallest of the new world species, the marine otter is also a very special otter – it is the only exclusively marine species apart from the sea otter. The greatest difference is in their bulk, as the largest male mink only weigh a little over 1.5kg, while otters average 7-12kg and can be even heavier.
