Eilean Choraidh
Eilean Choraidh, also known as Horse IslandHaswell-Smith (2004) p. 203 is an island in Loch Eriboll in Sutherland on the north coast of Scotland. It is about in extent and the highest point is above sea level. During the 19th century the Reay estate quarried lime from Eilean Choraidh, treated it in kilns on the nearby peninsula of Ard Neakie, and exported it by ship. The census of 1931 records a single male inhabitant, and there has been no indication of any permanent residents since then. This may be partly because Eilean Choraidh was used as a representation of the German battleship ''Tirpitz'' for target practice by Mosquito bombers of the Royal Air Force during World War II. The Ordnance Survey indicate the presence of two ruined buildings, one in the centre of the island north of a long wall that runs east to west and another at the north end. Today, the island is used for grazing sheep. A variety of wild mammals are present including otters, grey seals and cetaceans. B ...

List Of Outlying Islands Of Scotland
The outlying islands of Scotland are not part of the larger archipelagos and island groups of Scotland—the Hebrides, the Northern Isles or the Islands of the Forth and Islands of the Clyde, Clyde estuaries. None of these islands are currently inhabited and few of them ever were, although Hirta was occupied from the Neolithic age until 1930 and Stroma, Scotland, Stroma was permanently occupied until the 1970s and thereafter by lighthouse keepers and their families until 1996. Several other outlying islands have lighthouses, none of which is still staffed. In this list, an island is defined as "land that is surrounded by seawater on a daily basis, but not necessarily at all stages of the tide, excluding human devices such as bridges and causeways". A complication relating to membership of this list is that there are various descriptions of the scope of the Hebrides, the large group of islands that lie off Scotland's west coast. The ''Collins Encyclopedia of Scotland'' describe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
European Otter
The Eurasian otter (''Lutra lutra''), also known as the European otter, Eurasian river otter, European river otter, common otter, and Old World otter, is a semiaquatic mammal native to Eurasia and the Maghreb. The most widely distributed member of the otter subfamily (Lutrinae) of the weasel family (Mustelidae), it is found in the waterways and coasts of Europe, many parts of Asia, and parts of northern Africa. The Eurasian otter has a diet mainly of fish, and is strongly territorial. It is endangered in some parts of its range, but is recovering in others. Description The Eurasian otter is a typical species of the otter subfamily. Brown above and cream below, these long, slender creatures are well-equipped for their aquatic habits. Their bones show osteosclerosis, increasing their density to reduce buoyancy. This otter differs from the North American river otter by its shorter neck, broader visage, the greater space between the ears and its longer tail. However, the Eurasian ...

Virgularia Mirabilis
The slender sea pen (''Virgularia mirabilis'') is a species of sea pen in the family Virgulariidae, occurring throughout the Mediterranean and Western Europe, with some colonies being found on islands in the Mid-Atlantic. Description The slender sea pen stands upright in fine sediments. Their peduncles are buried underneath the sediment, while their raches extend into the water column. Due to their location in fine sediments, they are known to be able to withdraw into the sediment very quickly. They are able to reach up to 60 cm in length. It forms elongated and slender colonies, with polyps living on attached side branches. The polyps that form on the slender sea pen are able to form groups as large as 16 on each branch, with the central stem being only a few millimeters thick. The slender sea pen's color ranges from white, to beige, to a light yellow. Research shows that the nerve net in the slender sea pen seems to be well-developed. Habitat and distribution The sl ...

Algae
Algae ( , ; : alga ) is an informal term for any organisms of a large and diverse group of photosynthesis, photosynthetic organisms that are not plants, and includes species from multiple distinct clades. Such organisms range from unicellular microalgae, such as cyanobacteria, ''Chlorella'', and diatoms, to multicellular macroalgae such as kelp or brown algae which may grow up to in length. Most algae are aquatic organisms and lack many of the distinct cell and tissue types, such as stomata, xylem, and phloem that are found in embryophyte, land plants. The largest and most complex marine algae are called seaweeds. In contrast, the most complex freshwater forms are the Charophyta, a Division (taxonomy), division of green algae which includes, for example, ''Spirogyra'' and stoneworts. Algae that are carried passively by water are plankton, specifically phytoplankton. Algae constitute a Polyphyly, polyphyletic group because they do not include a common ancestor, and although Eu ...

Coral
Corals are colonial marine invertebrates within the subphylum Anthozoa of the phylum Cnidaria. They typically form compact Colony (biology), colonies of many identical individual polyp (zoology), polyps. Coral species include the important Coral reef, reef builders that inhabit tropical oceans and secrete calcium carbonate to form a hard skeleton. A coral "group" is a colony of very many cloning, genetically identical polyps. Each polyp is a sac-like animal typically only a few millimeters in diameter and a few centimeters in height. A set of tentacles surround a central mouth opening. Each polyp excretes an exoskeleton near the base. Over many generations, the colony thus creates a skeleton characteristic of the species which can measure up to several meters in size. Individual colonies grow by asexual reproduction of polyps. Corals also breed sexually by spawning: polyps of the same species release gametes simultaneously overnight, often around a full moon. Fertilized eggs form ...

Maerl
Maerl (also rhodolith) is a collective name for non- geniculate coralline red algae with a certain growth habit. Maerl grows at a rate of c. 1 mm per year. It accumulates as unattached particles and forms extensive beds in suitable sublittoral sites.Vize, S.; Blake, C.; Hinojosa, G. and Maggs, C.A. 2003. The distribution and composition of maerl beds in Northern Ireland. ''PMNHS Newsletter'' No.13 p.26 The term maerl originally refers to the branched growth form of Lemoine (1910) and ''rhodolith'' is a sedimentological or genetic term for both the nodular and branched growth forms (Basso et al., 2015). The terms rhodolith and maerl are used in very similar ways. A study in 2023 clarifies that maerl refers to only living, branched coralline thalli, while rhodolith includes unattached coralline red algae, both dead and alive. Description In Europe maerl beds occur throughout the Mediterranean, along most of the Atlantic coast from Portugal to Norway, and in the English Cha ...

Cetacean
Cetacea (; , ) is an infraorder of aquatic mammals belonging to the order Artiodactyla that includes whales, dolphins and porpoises. Key characteristics are their fully aquatic lifestyle, streamlined body shape, often large size and exclusively carnivorous diet. They propel themselves through the water with powerful up-and-down movements of their tail, which ends in a paddle-like fluke, using their flipper-shaped forelimbs to steer. While the majority of cetaceans live in marine environments, a small number reside solely in brackish water, brackish or fresh water. Having a cosmopolitan distribution, they can be found in some rivers and all of Earth's oceans, and many species migrate throughout vast ranges with the changing of the seasons. Cetaceans are famous for cetacean intelligence, their high intelligence, complex social behaviour, and the enormous size of some of the group's members. For example, the blue whale reaches a maximum confirmed length of and a weight of 173 tonne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grey Seal
The grey seal (''Halichoerus grypus'') is a large seal of the family Phocidae, which are commonly referred to as "true seals" or "earless seals". The only species classified in the genus ''Halichoerus'', it is found on both shores of the North Atlantic Ocean. In Latin, ''Halichoerus grypus'' means "hook-nosed sea pig". Its name is spelled gray seal in the United States; it is also known as Atlantic seal and the horsehead seal. Taxonomy There are two recognized subspecies of this seal: The type specimen of ''H. g. grypus'' ( Zoological Museum of Copenhagen specimen ZMUC M11-1525, caught in 1788 off the island of Amager, Danish part of the Baltic Sea) was believed lost for many years, but was rediscovered in 2016, and a DNA test showed it belonged to a Baltic Sea specimen rather than from Greenland, as had previously been assumed (because it was first described in Otto Fabricius' book on the animals in Greenland: ''Fauna Groenlandica''). The name ''H. g. g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ordnance Survey
The Ordnance Survey (OS) is the national mapping agency for Great Britain. The agency's name indicates its original military purpose (see Artillery, ordnance and surveying), which was to map Scotland in the wake of the Jacobite rising of 1745. There was also a more general and nationwide need in light of the potential threat of invasion during the Napoleonic Wars. Since 1 April 2015, the Ordnance Survey has operated as Ordnance Survey Ltd, a state-owned enterprise, government-owned company, 100% in public ownership. The Ordnance Survey Board remains accountable to the Secretary of State for Science, Innovation and Technology. It was also a member of the Public Data Group. Paper maps represent only 5% of the company's annual revenue. It produces digital map data, online route planning and sharing services and mobile apps, plus many other location-based products for business, government and consumers. Ordnance Survey mapping is usually classified as either "Scale (map), lar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Highland (council Area)
Highland (, ; ) is a council areas of Scotland, council area in the Scottish Highlands and is the largest local government area in both Scotland and the United Kingdom. It was the 7th most populous council area in Scotland at the United Kingdom Census 2011, 2011 census. It has land borders with the council areas of Aberdeenshire, Argyll and Bute, Moray and Perth and Kinross. The wider upland area of the Scottish Highlands after which the council area is named extends beyond the Highland council area into all the neighbouring council areas plus Angus, Scotland, Angus and Stirling (council area), Stirling. The Highland Council is based in Inverness, the area's largest settlement. The area is generally sparsely populated, with much of the inland area being mountainous with numerous lochs. The area includes Ben Nevis, the highest mountain in the British Isles. Most of the area's towns lie close to the eastern coasts. Off the west coast of the mainland the council area includes some ...
