Astrolirus Patricki
''Astrolirus patricki'' is a species of starfish in the family Brisingidae. It is a deep-sea species found on seamounts in the northwestern Pacific Ocean, at a depth of between . This species was discovered to science in 2013, and described in 2020. All known specimens of the species were observed attached to hexactinellid sponges, indicating a close, possibly commensal, relationship between both taxa. Due to this apparent relationship with sponges, the species was named ''Astrolirus patricki'' as a reference to Patrick Star, an anthropomorphic starfish character from the animated series ''SpongeBob SquarePants'', who is best friends with the titular character, an anthropomorphic sponge.

Starfish
Starfish or sea stars are star-shaped echinoderms belonging to the class Asteroidea (). Common usage frequently finds these names being also applied to ophiuroids, which are correctly referred to as brittle stars or basket stars. Starfish are also known as asteroids due to being in the class Asteroidea. About 1,900 species of starfish live on the seabed in all the world's oceans, from warm, tropical zones to frigid, polar regions. They are found from the intertidal zone down to abyssal depths, at below the surface. Starfish are marine invertebrates. They typically have a central disc and usually five arms, though some species have a larger number of arms. The aboral or upper surface may be smooth, granular or spiny, and is covered with overlapping plates. Many species are brightly coloured in various shades of red or orange, while others are blue, grey or brown. Starfish have tube feet operated by a hydraulic system and a mouth at the centre of the oral or lower surface. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brisingidae
The Brisingidae are a family of starfish found only in the deep sea. They inhabit both the Atlantic and Pacific Oceans at abyssal depths, and also occur in the Southern Ocean and around Antarctica at slightly shallower depths. The family was named after Brísingamen, a necklace belonging to Freya from Norse mythology that was stolen by Loki and hidden in the sea. Characteristics Members of this family have a small, Ophiurida-like disc, clearly demarcated from the arms, which number more than five. The disc is approximately circular with a rim of fused plates which gives rigidity. The madreporite is near the margin of the disc. The arms are long and tapering with the ratio of the arm length to the disc radius being greater than 6/1. There is an acute angle between them and they can be shed at the base where they are separated from the disc by a deep groove. After a narrow cylindrical portion, the part of the arms closest to the disc accommodates the gonadal tissues and wid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seamount
A seamount is a large geologic landform that rises from the ocean floor that does not reach to the water's surface (sea level), and thus is not an island, islet or cliff-rock. Seamounts are typically formed from extinct volcanoes that rise abruptly and are usually found rising from the seafloor to in height. They are defined by oceanographers as independent features that rise to at least above the seafloor, characteristically of conical form.IHO, 2008. Standardization of Undersea Feature Names: Guidelines Proposal form Terminology, 4th ed. International Hydrographic Organization and Intergovernmental Oceanographic Commission, Monaco. The peaks are often found hundreds to thousands of meters below the surface, and are therefore considered to be within the deep sea. During their evolution over geologic time, the largest seamounts may reach the sea surface where wave action erodes the summit to form a flat surface. After they have subsided and sunk below the sea surface such flat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pacific Ocean
The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the continents of Asia and Oceania in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), this largest division of the World Ocean—and, in turn, the hydrosphere—covers about 46% of Earth's water surface and about 32% of its total surface area, larger than Earth's entire land area combined .Pacific Ocean .

Hexactinellid
Hexactinellid sponges are sponges with a skeleton made of four- and/or six-pointed siliceous spicules, often referred to as glass sponges. They are usually classified along with other sponges in the phylum Porifera, but some researchers consider them sufficiently distinct to deserve their own phylum, Symplasma. Some experts believe glass sponges are thlongest-lived animals on earth these scientists tentatively estimate a maximum age of up to 15,000 years. Biology Glass sponges are relatively uncommon and are mostly found at depths from below the sea level. Although the species '' Oopsacas minuta'' has been found in shallow water, others have been found much deeper. They are found in all oceans of the world, although they are particularly common in Antarctic and Northern Pacific waters. They are more-or-less cup-shaped animals, ranging from in height, with sturdy lattice-like internal skeletons made up of fused spicules of silica. The body is relatively symmetrical, with a ...

Sponge
Sponges, the members of the phylum Porifera (; meaning 'pore bearer'), are a basal animal clade as a sister of the diploblasts. They are multicellular organisms that have bodies full of pores and channels allowing water to circulate through them, consisting of jelly-like mesohyl sandwiched between two thin layers of cells. Sponges have unspecialized cells that can transform into other types and that often migrate between the main cell layers and the mesohyl in the process. Sponges do not have nervous, digestive or circulatory systems. Instead, most rely on maintaining a constant water flow through their bodies to obtain food and oxygen and to remove wastes. Sponges were first to branch off the evolutionary tree from the last common ancestor of all animals, making them the sister group of all other animals. Etymology The term ''sponge'' derives from the Ancient Greek word ( 'sponge'). Overview Sponges are similar to other animals in that they are multicellular, he ...

Commensalism
Commensalism is a long-term biological interaction (symbiosis) in which members of one species gain benefits while those of the other species neither benefit nor are harmed. This is in contrast with mutualism, in which both organisms benefit from each other; amensalism, where one is harmed while the other is unaffected; parasitism, where one is harmed and the other benefits, and parasitoidism, which is similar to parasitism but the parasitoid has a free-living state and instead of just harming its host, it eventually ends up killing it. The commensal (the species that benefits from the association) may obtain nutrients, shelter, support, or locomotion from the host species, which is substantially unaffected. The commensal relation is often between a larger host and a smaller commensal; the host organism is unmodified, whereas the commensal species may show great structural adaptation consistent with its habits, as in the remoras that ride attached to sharks and other fishes.

SpongeBob SquarePants
''SpongeBob SquarePants'' (or simply ''SpongeBob'') is an American animated comedy television series created by marine science educator and animator Stephen Hillenburg for Nickelodeon. It chronicles the adventures of the title character and his aquatic friends in the fictional underwater city of Bikini Bottom. The fifth-longest-running American animated series, its high popularity has made it a media franchise. It is the highest rated Nickelodeon series and the most profitable property for Paramount Consumer Products, generating over $13 billion in merchandising revenue as of 2019. Many of the series's ideas originated in ''The Intertidal Zone'', an unpublished educational comic book Hillenburg created in 1989 to teach his students about undersea life. He began developing ''SpongeBob SquarePants'' into a television series in 1996, and in 1997, a seven-minute pilot was pitched to Nickelodeon. The network's executives wanted SpongeBob to be a child in school, but Hillenbur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SpongeBob SquarePants (character)
SpongeBob SquarePants is the protagonist of the American animated television series of the same name. Voiced by Tom Kenny, he is characterized by his optimism and childlike attitude. SpongeBob is commonly seen hanging out with his friend Patrick Star, working at the Krusty Krab, and attending Mrs. Puff's Boating School. SpongeBob was created and designed by Stephen Hillenburg, an artist and marine science educator. The character's name is derived from "Bob the Sponge", the host of Hillenburg's unpublished educational book ''The Intertidal Zone''. He drew the book while teaching marine biology to visitors of the Ocean Institute during the 1980s. Hillenburg began developing a show based on the premise shortly after the 1996 cancellation of ''Rocko's Modern Life'', which Hillenburg directed. SpongeBob's first appearance was in the pilot, " Help Wanted", which premiered on May 1, 1999. SpongeBob SquarePants has become popular among children and adults. The character has gar ...

World Register Of Marine Species
The World Register of Marine Species (WoRMS) is a taxonomic database that aims to provide an authoritative and comprehensive list of names of marine organisms. Content The content of the registry is edited and maintained by scientific specialists on each group of organism. These taxonomists control the quality of the information, which is gathered from the primary scientific literature as well as from some external regional and taxon-specific databases. WoRMS maintains valid names of all marine organisms, but also provides information on synonyms and invalid names. It is an ongoing task to maintain the registry, since new species are constantly being discovered and described by scientists; in addition, the nomenclature and taxonomy of existing species is often corrected or changed as new research is constantly being published. Subsets of WoRMS content are made available, and can have separate badging and their own home/launch pages, as "subregisters", such as the ''World List of ...

Brisingida
The Brisingids are deep-sea-dwelling starfish in the order Brisingida. Description These starfish have between 6 to 18 long, attenuated arms which they use for suspension feeding. Other characteristics include a single series of marginals, a fused ring of disc plates, the lack of actinal plates, a spool-like ambulacral column, reduced abactinal plates, and crossed pedicellariae. They are 40 times the size of disk radius and have 7-20 flexible spiny arms. Distribution Brisingida occur in a number of deep-sea locations, particularly in the Caribbean and New Zealand. This type of species are found of varying size especially in the eastern Pacific Ocean at a depth of 1,820–2,418 m. Taxonomy The Brisingida contain two families, with 18 genera: *Family Brisingidae, G.O. Sars, 1875 **Genus ''Astrolirus'', Fisher, 1917 — (two species) **Genus '' Astrostephane'', Fisher, 1917 — (two species) **Genus ''Brisinga'' Asbjørnsen, 1856 (synonym: ''Craterobrisinga'', Fisher, 1916) — ...
