Goniodoris Castanea
''Goniodoris castanea'' is a species of sea slug, a dorid nudibranch, a marine gastropod mollusc in the family Goniodorididae. Distribution This species was first described from Salcombe Estuary, Devon. It has subsequently been reported widely in Britain and Ireland and from Norway to the Mediterranean Sea.Thompson, T.E. and Brown, G.H., 1984. Biology of Opisthobranch Molluscs, Volume II.

Joshua Alder
Joshua Alder (7 April 1792 – 21 January 1867) was a British cheesemonger and amateur zoologist and malacologist. As such, he specialized in the Tunicata, and in gastropods. He was a member of the 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, a street in central Newcastle. He sold that business and became a shareholder in the Northumberland District Bank, and a gentleman of leisure. A financial crash in 1857 led to the collap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opi ...

Tunicate
A tunicate is a marine invertebrate animal, a member of the subphylum Tunicata (). It is part of the Chordata, a phylum which includes all animals with dorsal nerve cords and notochords (including vertebrates). The subphylum was at one time called Urochordata, and the term urochordates is still sometimes used for these animals. They are the only chordates that have lost their myomeric segmentation, with the possible exception of the 'seriation of the gill slits'. Some tunicates live as solitary individuals, but others replicate by budding and become colonies, each unit being known as a zooid. They are marine filter feeders with a water-filled, sac-like body structure and two tubular openings, known as siphons, through which they draw in and expel water. During their respiration and feeding, they take in water through the incurrent (or inhalant) siphon and expel the filtered water through the excurrent (or exhalant) siphon. Most adult tunicates are sessile, immobile an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Devon
Devon ( , historically known as Devonshire , ) is a ceremonial and non-metropolitan county in South West England. The most populous settlement in Devon is the city of Plymouth, followed by Devon's county town, the city of Exeter. Devon is a coastal county with cliffs and sandy beaches. Home to the largest open space in southern England, Dartmoor (), the county is predominately rural and has a relatively low population density for an English county. The county is bordered by Somerset to the north east, Dorset to the east, and Cornwall to the west. The county is split into the non-metropolitan districts of East Devon, Mid Devon, North Devon, South Hams, Teignbridge, Torridge, West Devon, Exeter, and the unitary authority areas of Plymouth, and Torbay. Combined as a ceremonial county, Devon's area is and its population is about 1.2 million. Devon derives its name from Dumnonia (the shift from ''m'' to ''v'' is a typical Celtic consonant shift).

Salcombe
Salcombe is a popular resort town in the South Hams district of Devon, south west England. The town is close to the mouth of the Kingsbridge Estuary, mostly built on the steep west side of the estuary. It lies within the South Devon Area of Outstanding Natural Beauty (AONB). The town's extensive waterfront and the naturally sheltered harbour formed by the estuary gave rise to its success as a boat and shipbuilding and sailing port and, in modern times, tourism especially in the form of pleasure boats and yachting. The town is also home to a traditional shellfish fishing industry. The town is part of the electoral ward of Salcombe and Malborough, for which the 2011 census recorded a total population of 3,353. Kingsbridge Estuary (actually a ria or drowned valley) lies between Bolt Head and Sharpitor on the west and Portlemouth Down on the east, and runs inland for some . The estuary was designated a Site of Special Scientific Interest in February 1987 and is also a Local N ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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.

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.

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.
