William Harper Pease
William Harper Pease (1824–1871) was a 19th-century American conchologist, shell collector and malacologist. He described many species of Indo-Pacific marine mollusks from the Cuming collection. He moved in 1849 to Honolulu Honolulu (; ) is the capital and largest city of the U.S. state of Hawaii, which is in the Pacific Ocean. It is an unincorporated county seat of the consolidated City and County of Honolulu, situated along the southeast coast of the island ..., from where he continued his research One of the genera he described and named was the sea slug genus: '' Philinopsis'' Pease, 1860 Several species were named in his honor : '' Favartia peasei'' (Tryon, 1880), '' Conus peasei'' J. Brazier, 1877, ''Amygdalum peasei'' W. Newcomb, 1870 and '' Hypselodoris peasei'' (Bergh, 1880) For many years, no image of Pease was known, until a 2021 paper revealed that two (one shown above) had been discovered in the Bishop Museum Archives, Honolulu.

Chiton
Chitons () are marine molluscs of varying size in the class Polyplacophora (), formerly known as Amphineura. About 940 extant and 430 fossil species are recognized. They are also sometimes known as gumboots or sea cradles or coat-of-mail shells or suck-rocks, or more formally as loricates, polyplacophorans, and occasionally as polyplacophores. Chitons have a shell composed of eight separate shell plates or valves. These plates overlap slightly at the front and back edges, and yet articulate well with one another. Because of this, the shell provides protection at the same time as permitting the chiton to flex upward when needed for locomotion over uneven surfaces, and even allows the animal to curl up into a ball when dislodged from rocks. The shell plates are encircled by a skirt known as a girdle. Habitat Chitons live worldwide, from cold waters through to the tropics. They live on hard surfaces, such as on or under rocks, or in rock crevices. Some species live quite hi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hawaiian Islands
The Hawaiian Islands ( haw, Nā Mokupuni o Hawai‘i) are an archipelago of eight major islands, several atolls, and numerous smaller islets in the North Pacific Ocean, extending some from the island of Hawaii in the south to northernmost Kure Atoll. Formerly the group was known to Europeans and Americans as the Sandwich Islands, a name that James Cook chose in honor of the 4th Earl of Sandwich, the then First Lord of the Admiralty. Cook came across the islands by chance when crossing the Pacific Ocean on his Third Voyage in 1778, on board HMS ''Resolution''; he was later killed on the islands on a return visit. The contemporary name of the islands, dating from the 1840s, is derived from the name of the largest island, Hawaii Island. Hawaii sits on the Pacific Plate and is the only U.S. state that is not geographically connected to North America. It is part of the Polynesia subregion of Oceania. The state of Hawaii occupies the archipelago almost in its entirety (includin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acanthochitonidae
Acanthochitonidae is a family of chitons, marine molluscs in the class Polyplacophora. Description These small to large chitons are characterised by a broad girdle with erect tufts of up to ten large bristles. The coarsely granular valves of the shell are partially overlapped by the girdle. This girdle is all covered by coarse spines. The articulating flange, or ''articulamentum'', is well developed. The margin of the cephalic plate has about five slits. The lateral'' insertion plates'' all have a single notch. Genera According to the World Register of Marine Species (WoRMS) the following genera are included in this family * Acanthochitona Gray, 1821 * Amycula * Bassethullia Pilsbry, 1928 * Choneplax Carpenter MS, Dall, 1882 * Craspedochiton Shuttleworth, 1853 * Craspedoplax Iredale & Hull, 1925 * Cryptoconchus de Blainville MS, Burrow, 1815 * Leptoplax Carpenter MS, Dall, 1882 * Notoplax ''Notoplax'' is a genus of chitons in the family Acanthochitonidae.Bouchet, P. ...

Endemic Fauna Of Hawaii
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
