Joshua Alder
Joshua Alder (7 April 1792 – 21 January 1867) was a British cheese, cheesemonger and amateur zoologist and malacologist. As such, he specialized in the Tunicata, and in gastropods. He was a member of the Hancock Museum, Natural History Society of Northumberland and Durham, and an early member of the Literary and Philosophical Society of Newcastle upon Tyne, alongside Joseph Swan and Robert Stephenson. He corresponded with Charles Darwin. His drawings are in the collections of the Great North Museum: Hancock and the British Museum. Ravensworth Terrace From 1841 to 1857 Alder was a tenant at 5 Ravensworth Terrace in the Summerhill area of Newcastle upon Tyne, which he shared with his sister Mary, a woman of independent means, and their two female servants. During this time, he ran a cheese shop in The Side, Newcastle upon Tyne, The Side, a street in central Newcastle. He sold that business and became a shareholder in the Northumberland District Bank, and a gentleman of leis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cullercoats
Cullercoats is a coastal settlement in the metropolitan borough of North Tyneside, Tyne and Wear, North East England. Historically in Northumberland, it has now been absorbed into the wider Tyneside conurbation, sitting between Tynemouth to the south and Whitley Bay to the north. The population of this North Tyneside ward at the 2011 census was 9,202. There is a semi-circular sandy beach with cliffs and six caves, and the village is a popular destination for day-trippers. It also acts as an attractive dormitory town for nearby Newcastle upon Tyne. The name is thought to derive from dove (or "culver") Dovecote, cotes. History and architecture Cullercoats village was founded in 1539. Historically the village depended on fishing; there was also local coal mining in so-called bell pits. The coal was used to fire salt pan (evaporation), salt pans (now long gone) on the field now known as the boat field. As a port, Cullercoats was used to export both salt and coal from the 1670s.

Hydroid (zoology)
Hydroids are a life stage for most animals of the class Hydrozoa, small predators related to jellyfish. Some hydroids such as the freshwater '' Hydra'' are solitary, with the polyp attached directly to the substrate. When these produce buds, they become detached and grow on as new individuals. The majority of hydroids are colonial. The original polyp is anchored to a solid substrate and forms a bud which remains attached to its parent. This in turn buds and in this way a stem is formed. The arrangement of polyps and the branching of the stem is characteristic of the species. Some species have the polyps budding directly off the stolon which roots the colony. The polyps are connected by epidermis which surrounds a gastrovascular cavity. The epidermis secretes a chitinous skeleton which supports the stem and in some hydroids, the skeleton extends into a cup shape surrounding the polyp. Most of the polyps are gastrozooids or feeding polyps, but some are specialised reprodu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cerata
:''The tortrix moth genus ''Cerata'' is considered a junior synonym of ''Cydia. Cerata, singular ceras, are anatomical structures found externally in nudibranch sea slugs, especially in aeolid nudibranchs, marine opisthobranch gastropod mollusks in the clade Aeolidida. The word ceras comes from the Greek word "κέρας", meaning "horn", a reference to the shape of these structures. Cerata are dorsal and lateral outgrowths on the upper surfaces of the body of these nudibranchs. Function Cerata greatly extend the surface area of nudibranchs and aid in respiration, the process of gas exchange for metabolic use. Cerata are also used, in some cases, for attack and defense. In many aeolid nudibranchs, the digestive system extends into the cerata. These nudibranchs eat stinging celled animals (Cnidarians) such as anemones, hydroids and sea fans or Portuguese men o' war. The stinging cells or nematocysts are passed unharmed through the digestive system to cnidosacs at the tips of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
New England
New England is a region comprising six states in the Northeastern United States: Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island, and Vermont. It is bordered by the state of New York to the west and by the Canadian provinces of New Brunswick to the northeast and Quebec to the north. The Atlantic Ocean is to the east and southeast, and Long Island Sound is to the southwest. Boston is New England's largest city, as well as the capital of Massachusetts. Greater Boston is the largest metropolitan area, with nearly a third of New England's population; this area includes Worcester, Massachusetts (the second-largest city in New England), Manchester, New Hampshire (the largest city in New Hampshire), and Providence, Rhode Island (the capital of and largest city in Rhode Island). In 1620, the Pilgrims, Puritan Separatists from England, established Plymouth Colony, the second successful English settlement in America, following the Jamestown Settlement in Virginia foun ...

Newfoundland
Newfoundland and Labrador (; french: Terre-Neuve-et-Labrador; frequently abbreviated as NL) is the easternmost province of Canada, in the country's Atlantic region. The province comprises the island of Newfoundland and the continental region of Labrador, having a total size of 405,212 square kilometres (156,500 sq mi). In 2021, the population of Newfoundland and Labrador was estimated to be 521,758. The island of Newfoundland (and its smaller neighbouring islands) is home to around 94 per cent of the province's population, with more than half residing in the Avalon Peninsula. Labrador borders the province of Quebec, and the French overseas collectivity of Saint Pierre and Miquelon lies about 20 km west of the Burin Peninsula. According to the 2016 census, 97.0 per cent of residents reported English as their native language, making Newfoundland and Labrador Canada's most linguistically homogeneous province. A majority of the population is descended from English and Irish s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North Sea
The North Sea lies between Great Britain, Norway, Denmark, Germany, the Netherlands and Belgium. An epeiric sea on the European continental shelf, it connects to the Atlantic Ocean through the English Channel in the south and the Norwegian Sea in the north. It is more than long and wide, covering . It hosts key north European shipping lanes and is a major fishery. The coast is a popular destination for recreation and tourism in bordering countries, and a rich source of energy resources, including wind and wave power. The North Sea has featured prominently in geopolitical and military affairs, particularly in Northern Europe, from the Middle Ages to the modern era. It was also important globally through the power northern Europeans projected worldwide during much of the Middle Ages and into the modern era. The North Sea was the centre of the Vikings' rise. The Hanseatic League, the Dutch Republic, and the British each sought to gain command of the North Sea and access t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Albany Hancock
Albany Hancock (24 December 1806 – 1873), English naturalist, biologist and supporter of Charles Darwin, was born on Christmas Eve in Newcastle upon Tyne. He is best known for his works on marine animals and coal-measure fossils. Albany Hancock was brother of the naturalist John Hancock. The brothers lived with their sister, Mary Jane, at 4 St. Mary's Terrace, Newcastle, now part of a listed terrace at 14-20 Great North Road. Early life and education Hancock was educated at The Royal Grammar School, before becoming a trainee for a local solicitor. He completed the expected period in articles and passed all the required examinations to become a solicitor himself, even going so far as to acquire an office in Newcastle with a view to establishing his own practice. Career Hancock's true interests lay elsewhere, and after a brief period of employment with a manufacturing firm, dedicated the rest of his life to his true calling, natural history.

Mollusc
Mollusca is the second-largest phylum of invertebrate animals after the Arthropoda, the members of which are known as molluscs or mollusks (). Around 85,000 extant species of molluscs are recognized. The number of fossil species is estimated between 60,000 and 100,000 additional species. The proportion of undescribed species is very high. Many taxa remain poorly studied. Molluscs are the largest marine phylum, comprising about 23% of all the named marine organisms. Numerous molluscs also live in freshwater and terrestrial habitats. They are highly diverse, not just in size and anatomical structure, but also in behaviour and habitat. The phylum is typically divided into 7 or 8 taxonomic classes, of which two are entirely extinct. Cephalopod molluscs, such as squid, cuttlefish, and octopuses, are among the most neurologically advanced of all invertebrates—and either the giant squid or the colossal squid is the largest known invertebrate species.

Gastropod
The gastropods (), commonly known as snails and slugs, belong to a large taxonomic class of invertebrates within the phylum Mollusca called Gastropoda (). This class comprises snails and slugs from saltwater, from freshwater, and from land. There are many thousands of species of sea snails and slugs, as well as freshwater snails, freshwater limpets, and land snails and slugs. The class Gastropoda contains a vast total of named species, second only to the insects in overall number. The fossil history of this class goes back to the Late Cambrian. , 721 families of gastropods are known, of which 245 are extinct and appear only in the fossil record, while 476 are currently extant with or without a fossil record. Gastropoda (previously known as univalves and sometimes spelled "Gasteropoda") are a major part of the phylum Mollusca, and are the most highly diversified class in the phylum, with 65,000 to 80,000 living snail and slug species.
