The sea otter is a marine mammal native to the coasts of the northern and eastern North Pacific Ocean. Adult sea otters weigh between 14 and 45 kg, making them the heaviest members of the weasel family, but among the smallest marine mammals. Unlike most marine mammals, the sea otter's primary form of insulation is an exceptionally thick coat of fur, the densest in the animal kingdom. Although it can walk on land, the sea otter is capable of living in the ocean; the sea otter inhabits nearshore environments. It preys on marine invertebrates such as sea urchins, various molluscs and crustaceans, some species of fish, its foraging and eating habits are noteworthy in several respects. First, its use of rocks to dislodge prey and to open shells makes it one of the few mammal species to use tools. In most of its range, it is a keystone species, controlling sea urchin populations which would otherwise inflict extensive damage to kelp forest ecosystems, its diet includes prey species that are valued by humans as food, leading to conflicts between sea otters and fisheries.
Sea otters, whose numbers were once estimated at 150,000–300,000, were hunted extensively for their fur between 1741 and 1911, the world population fell to 1,000–2,000 individuals living in a fraction of their historic range. A subsequent international ban on hunting, sea otter conservation efforts, reintroduction programs into populated areas have contributed to numbers rebounding, the species occupies about two-thirds of its former range; the recovery of the sea otter is considered an important success in marine conservation, although populations in the Aleutian Islands and California have declined or have plateaued at depressed levels. For these reasons, the sea otter remains classified as an endangered species; the sea otter is the heaviest member of the family Mustelidae, a diverse group that includes the 13 otter species and terrestrial animals such as weasels and minks. It is unique among the mustelids in not making dens or burrows, in having no functional anal scent glands, in being able to live its entire life without leaving the water.
The only member of the genus Enhydra, the sea otter is so different from other mustelid species that, as as 1982, some scientists believed it was more related to the earless seals. Genetic analysis indicates the sea otter and its closest extant relatives, which include the African speckle-throated otter, European otter, African clawless otter and oriental small-clawed otter, shared an ancestor 5 million years ago. Fossil evidence indicates the Enhydra lineage became isolated in the North Pacific 2 million years ago, giving rise to the now-extinct Enhydra macrodonta and the modern sea otter, Enhydra lutris. One related species has been described, from the Pleistocene of East Anglia; the modern sea otter evolved in northern Hokkaidō and Russia, spread east to the Aleutian Islands, mainland Alaska, down the North American coast. In comparison to cetaceans and pinnipeds, which entered the water 50, 40, 20 million years ago the sea otter is a relative newcomer to a marine existence. In some respects, the sea otter is more adapted to water than pinnipeds, which must haul out on land or ice to give birth.
The full genome of the northern sea otter was sequenced in 2017 and may allow for examination of the sea otter's evolutionary divergence from terrestrial mustelids. The first scientific description of the sea otter is contained in the field notes of Georg Steller from 1751, the species was described by Linnaeus in his Systema Naturae of 1758. Named Lutra marina, it underwent numerous name changes before being accepted as Enhydra lutris in 1922; the generic name Enhydra, derives from the Ancient Greek en/εν "in" and hydra/ύδρα "water", meaning "in the water", the Latin word lutris, meaning "otter". The sea otter was sometimes referred to as the "sea beaver", being the marine fur-bearer similar in commercial value to the terrestrial beaver. Rodents are not related to otters, which are carnivorans, it is not to be confused with the marine otter, a rare otter species native to the southern west coast of South America. A number of other otter species, while predominantly living in fresh water, are found in marine coastal habitats.
The extinct sea mink of northeast North America is another mustelid that had adapted to a marine environment. Three subspecies of the sea otter are recognized with distinct geographical distributions. Enhydra lutris lutris, the Asian sea otter, ranges from the Kuril Islands north of Japan to Russia's Commander Islands in the western Pacific Ocean. In the eastern Pacific Ocean, E. l. kenyoni, the northern sea otter, is found from Alaska's Aleutian Islands to Oregon and E. l. nereis, the southern sea otter, is native to central and southern California. The Asian sea otter is the largest subspecies and has a wider skull and shorter nasal bones than both other subspecies. Northern sea otters possess longer mandibles while southern sea otters have longer rostrums and smaller teeth; the sea otter is one of the smallest marine mammal species. Male sea otters weigh 22 to 45 kg and are 1.2 to 1.5 m in length, though specimens up to 54 kg have been recorded. Females are smaller, measuring 1.0 to 1.4 m in length.

The HBMS Cascarilla is the second of four Damen Stan 3007 patrol vessels commissioned by the Royal Bahamas Defence Force. The Cascarilla, her sister ships are 30 metres long and 7 metres wide, have a maximum speed of 24 knots, she and her sister ships have a shallow draft, for inshore work. She is designed for missions of up to five days, she is designed for a crew of 13. While most modern vessels are designed with a clipper bow, Damen built the Cascarilla, her sister ships, with an "axe bow", a new style of bow intended to make for easier sea-keeping in rough weather. At her stern she is equipped with a stern launching ramp, which enables her to deploy and retrieve her waterjet-propelled pursuit boat, without first coming to a stop. In early 2016 the Cascarilla was damaged in a grounding. Repairs cost $23,000. On June 15, 2016, the Cascarilla exchanged gunfire with individuals they believed were Dominican Republic fish poachers. No crew members were injured. On January 2, 2018, the Cascarilla intercepted a 40 foot sailing sloop carrying 91 undocumented migrants.
On March 27, 2018, an undocumented Haitian immigrant triggered a search when he was able to phone Bahamanian officials and report the smuggling vessel he was on had sprung a leak. The Royal Bahamas Defence Force requested the United States Coast Guard to dispatch aircraft to help locate the vessel. After the USCG located the vessel, the Cascarilla intercepted a smuggling sloop and rescued 89 undocumented migrants from Haiti
The 2016 Brunei Super League was the 4th season of the Brunei Super League, the top Bruneian professional league for association football clubs, since its establishment in 2012. The season began on 12 March 2016 and concluded on 30 September 2016. MS ABDB came into the season as defending champions of the 2015 season. Kota Ranger and Kasuka entered. NFABD concluded the league after only one round, which meant that MS ABDB retained the title with seven wins out of nine. A total of 10 teams participated in the 2016 Super League season, eight from the previous season and two promoted teams. Kota Ranger were promoted as champions of the country's second tier while Kasuka were promoted, that's despite finishing outside the top two places in third but as Tabuan Muda B finished second and are ineligible for promotion, it was awarded to Kasuka instead. Kota Ranger and Kasuka replaced IKLS and Kilanas who were relegated in 2015. Note: Table lists in alphabetical order. Soccerway RSSSF National Football Association of Brunei Darussalam website
