Coral Reef
A coral reef is an underwater ecosystem characterized by reef-building corals. Reefs are formed of colonies of coral polyps held together by calcium carbonate. Most coral reefs are built from stony corals, whose polyps cluster in groups. Coral belongs to the class Anthozoa in the animal phylum Cnidaria, which includes sea anemones and jellyfish. Unlike sea anemones, corals secrete hard carbonate exoskeletons that support and protect the coral. Most reefs grow best in warm, shallow, clear, sunny and agitated water. Coral reefs first appeared 485 million years ago, at the dawn of the Early Ordovician, displacing the microbial and sponge reefs of the Cambrian. Sometimes called ''rainforests of the sea'', shallow coral reefs form some of Earth's most diverse ecosystems. They occupy less than 0.1% of the world's ocean area, about half the area of France, yet they provide a home for at least 25% of all marine species, including fish, mollusks, worms, crustaceans, ...

Humpback Whale
The humpback whale (''Megaptera novaeangliae'') is a species of baleen whale. It is a rorqual (a member of the family Balaenopteridae) and is the monotypic taxon, only species in the genus ''Megaptera''. Adults range in length from and weigh up to . The humpback has a distinctive body shape, with long pectoral fins and tubercles on its head. It is known for Cetacean surfacing behaviour, breaching and other distinctive surface behaviors, making it popular with whale watching, whale watchers. Males produce a complex Whale sound, song that typically lasts from 4 to 33 minutes. Found in oceans and list of seas, seas around the world, humpback whales typically animal migration, migrate between feeding areas towards the poles and breeding areas near the equator.

Guano
Guano (Spanish from ) is the accumulated excrement of seabirds or bats. Guano is a highly effective fertiliser due to the high content of nitrogen, phosphate, and potassium, all key nutrients essential for plant growth. Guano was also, to a lesser extent, sought for the production of gunpowder and other explosive materials. The 19th-century seabird guano trade played a pivotal role in the development of modern Intensive farming, input-intensive farming. The demand for guano spurred the human colonisation of remote bird islands in many parts of the world. Unsustainable seabird guano mining processes can result in permanent habitat destruction and the loss of millions of seabirds. Bat guano is found in caves throughout the world. Many cave ecosystems are wholly dependent on bats to provide nutrients via their guano which supports bacteria, Fungus, fungi, invertebrates, and vertebrates. The loss of bats from a cave can result in the extinction of species that rely on their guano ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Corn Crake
The corn crake, corncrake or landrail (''Crex crex'') is a bird in the rail family. It breeds in Europe and Asia as far east as western China, and migrates to Africa for the Northern Hemisphere's winter. It is a medium-sized crake with buff- or grey-streaked brownish-black upperparts, chestnut markings on the wings, and blue-grey underparts with rust-coloured and white bars on the flanks and undertail. The strong bill is flesh-toned, the iris is pale brown, and the legs and feet are pale grey. Juveniles are similar in plumage to adults, and downy chicks are black, as with all rails. There are no subspecies, although individuals from the east of the breeding range tend to be slightly paler than their western counterparts. The male's call is a loud ''krek krek'', from which the scientific name is derived. The corn crake is larger than its closest relative, the African crake, which shares its wintering range; that species is also darker-plumaged, and has a plainer face. The ...

Plover
Plovers ( , ) are members of a widely distributed group of wader, wading birds of subfamily Charadriinae. The term "plover" applies to all the members of the subfamily, though only about half of them include it in their name. Species list in taxonomic sequence The taxonomy of family Charadriidae is unsettled. At various times the plovers, dotterels, and lapwings of family Charadriidae have been distributed among several subfamilies, with Charadriinae including most of the species. The International Ornithological Congress (IOC) and the Clements taxonomy do not assign species to subfamilies. The South American Classification Committee of the American Ornithological Society (AOS) includes all of the species in Charadriinae. The North American Classification Committee of the AOS and BirdLife International's ''Handbook of the Birds of the World'' separate the four members of genus ''Pluvialis'' as subfamily Pluvialinae. The IOC recognizes these 69 species of plovers, dottere ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Godwit
Godwits are a group of four large, long-billed, long-legged and strongly bird migration, migratory waders of the bird genus ''Limosa''. Their long bills allow them to probe deeply in the sand for aquatic worms and mollusca, molluscs. In their winter range, they flock together where food is plentiful. They frequent tidal shorelines, breeding in northern climates in summer and migrating south in winter. A female bar-tailed godwit made a flight of 29,000 km (18,000 mi), flying of it without stopping. In 2020 a male bar-tailed godwit flew about non-stop in its migration from Alaska to New Zealand, previously a record for avian non-stop flight. In October 2022, a 5 month old, male bar-tailed godwit was tracked from Alaska to Tasmania, a trip that took 11 days, and recorded a non-stop flight of . The godwits can be distinguished from the curlews by their straight or slightly upturned bills, and from the dowitchers by their longer legs. The winter plumages are fairly drab, ...

Noddy (tern)
The noddies, forming the genus ''Anous'', is a genus of seabirds in family Laridae which also contains the gulls, terns and skimmers. The genus contains five species. The noddies inhabit tropical oceans and have a worldwide distribution, ranging from Hawaii to the Tuamotu Archipelago and Australia in the Pacific Ocean, from the Red Sea to the Seychelles and Australia in the Indian Ocean and in the Caribbean to Tristan da Cunha in the Atlantic Ocean. They nest in colonies on cliffs or in short trees or shrubs, seldom on the ground. The female lays one egg in each breeding season.''Anous'' TOLWEB These birds feed on small fish which they catch by dipping their bills beneath the surface while flying; they do not Seabird#Plunge diving, plunge dive.

Tern
Terns are seabirds in the family Laridae, subfamily Sterninae, that have a worldwide distribution and are normally found near the sea, rivers, or wetlands. Terns are treated in eleven genera in a subgroup of the family Laridae, which also includes several genera of gulls and the skimmers (''Rynchops''). They are slender, lightly built birds with long, forked tails, narrow wings, long bills, and relatively short legs. Most species are pale grey above and white below with a contrasting black cap to the head, but the marsh terns, the black-bellied tern, the Inca tern, and some noddies have dark body plumage for at least part of the year. The sexes are identical in appearance, but young birds are readily distinguishable from adults. Terns have a non-breeding plumage, which usually involves a white forehead and much-reduced black cap. Terns are long-lived birds and are relatively free from natural predators and parasites; most species are declining in numbers due directly o ...

Boatswain (bird)
A boatswain ( , ), bo's'n, bos'n, or bosun, also known as a deck boss, or a qualified member of the deck department, or the third hand on a fishing vessel, is the most senior Naval rating, rate of the deck department and is responsible for the components of a ship's Hull (watercraft), hull. The boatswain supervises the other members of the ship's deck department, and typically is not a watchstanding, watchstander, except on vessels with small crews. Additional duties vary depending upon ship, crew, and circumstances. History The word ''boatswain'' has been in the English language since approximately 1450. It is derived from late Old English language, Old English ''batswegen'', from ''bat'' (''boat'') concatenated with Old Norse language, Old Norse ''sveinn'' (''wikt:swain, swain''), meaning a young man, apprentice, a follower, Retinue, retainer or Servant (domestic), servant. Directly translated to modern Norwegian it would be ''båtsvenn'', while the actual crew title in Norwe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Man-of-war Bird
In Royal Navy jargon, a man-of-war (also man-o'-war, or simply man) was a powerful warship or frigate of the 16th to the 19th century, that was frequently used in Europe. Although the term never acquired a specific meaning, it was usually reserved for a sailing ship armed with cannon. The rating system of the Royal Navy classified men-of-war into six "rates", a "first-rate" having the greatest armament, and a "sixth-rate" the least. Description The man-of-war was developed in Portugal in the early 15th century from earlier roundships with the addition of a second mast to form the carrack. The 16th century saw the carrack evolve into the galleon and then the ship of the line. The evolution of the term has been given thus: The man-of-war design developed by John Hawkins (naval commander), Sir John Hawkins was a type of galleon which had three masts, each with three to four sails. The ship could be up to 60 metres long and could have up to 124 guns: four at the bow, eight at th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Gannet
Gannets are seabirds comprising the genus ''Morus'' in the family Sulidae, closely related to boobies. They are known as 'solan' or 'solan goose' in Scotland. A common misconception is that the Scottish name is 'guga' but this is the Gaelic name referring to the chicks only. Gannets are large white birds with yellowish heads, black-tipped wings and long bills. Northern gannets are the largest seabirds in the North Atlantic, having a wingspan of up to . The other two species occur in the temperate seas around southern Africa, southern Australia, and New Zealand. Etymology "Gannet" is derived from Old English ''ganot'' meaning "strong or masculine", ultimately from the same Old Germanic root as "gander". Taxonomy ''Morus'' is derived from Ancient Greek ''moros'' "stupid" or "foolish" due to lack of fear shown by breeding gannets and boobies, allowing them to be easily killed. Behaviour Hunting Gannets hunt fish by diving into the sea from a height of and pursuing t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
