Platylepas Ophiophila
''Platylepas ophiophila'', commonly known as the sea snake barnacle, is a species of barnacle in the family Platylepadidae. It is native to the Indo-Pacific Ocean where it lives as a symbiont of a sea snake. Ecology ''Platylepas ophiophila'' is found living in association with several species of sea snake as an ectosymbiont. The barnacle adheres to the snake's skin, and has ribs that penetrate the snake's skin to make the attachment more secure. Nevertheless, the barnacle usually becomes detached when the snake sheds its skin. Barnacles breed by internal fertilisation, so individuals of this species have to be located adjacent to another individual in order to reproduce. Despite the fact that sea snakes are mobile and generally solitary, about half the sea snakes support barnacles. The barnacle may have adopted this lifestyle as a result of intense competition for space on coral reefs, rocks and other hard substrates; the advantages for the barnacle are freedom from predators, ...

Barnacle
A barnacle is a type of arthropod constituting the subclass Cirripedia in the subphylum Crustacea, and is hence related to crabs and lobsters. Barnacles are exclusively marine, and tend to live in shallow and tidal waters, typically in erosive settings. They are sessile (nonmobile) and most are suspension feeders, but those in infraclass Rhizocephala are highly specialized parasites on crustaceans. They have four nektonic (active swimming) larval stages. Around 1,000 barnacle species are currently known. The name is Latin, meaning "curl-footed". The study of barnacles is called cirripedology. Description Barnacles are encrusters, attaching themselves temporarily to a hard substrate or a symbiont such as a whale ( whale barnacles), a sea snake ('' Platylepas ophiophila''), or another crustacean, like a crab or a lobster (Rhizocephala). The most common among them, "acorn barnacles" ( Sessilia), are sessile where they grow their shells directly onto the substrate. Peduncul ...

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 opini ...

Platylepadidae
In the past, Platylepadidae has been considered a family of barnacle A barnacle is a type of arthropod constituting the subclass Cirripedia in the subphylum Crustacea, and is hence related to crabs and lobsters. Barnacles are exclusively marine, and tend to live in shallow and tidal waters, typically in eros ...s of the order Sessilia. Research published in 2021 by Chan et al. resulted in the genera of Platylepadidae being merged with that of Balanidae, except Stephanolepas which was moved to Chelonibiidae. In the same work, Sessilia was not retained as an order of barnacles. References Obsolete arthropod taxa {{Crustacean-stub ...

Symbiosis
Symbiosis (from Greek , , "living together", from , , "together", and , bíōsis, "living") is any type of a close and long-term biological interaction between two different biological organisms, be it mutualistic, commensalistic, or parasitic. The organisms, each termed a symbiont, must be of different species. In 1879, Heinrich Anton de Bary defined it as "the living together of unlike organisms". The term was subject to a century-long debate about whether it should specifically denote mutualism, as in lichens. Biologists have now abandoned that restriction. Symbiosis can be obligatory, which means that one or more of the symbionts depend on each other for survival, or facultative (optional), when they can generally live independently. Symbiosis is also classified by physical attachment. When symbionts form a single body it is called conjunctive symbiosis, while all other arrangements are called disjunctive symbiosis."symbiosis."

Hydrophiinae
Hydrophiinae is a subfamily of venomous snakes in the family Elapidae. It contains most sea snakes and many genera of venomous land snakes found in Australasia, such as the taipans (''Oxyuranus''), tiger snakes (''Notechis''), Pseudonaja, brown snakes (''Pseudonaja'') and Acanthophis, death adders (''Acanthophis''). Genera According to the Reptile Database, Hydrophiinae contains the following 38 genera: (Sea snakes are marked with asterisks.) References {{Taxonbar, from=Q460286 Elapidae Venomous snakes ...

Substrate (biology)
In biology, a substrate is the surface on which an organism (such as a plant, fungus, or animal) lives. A substrate can include biotic or abiotic materials and animals. For example, encrusting algae that lives on a rock (its substrate) can be itself a substrate for an animal that lives on top of the algae. Inert substrates are used as growing support materials in the hydroponic cultivation of plants. In biology substrates are often activated by the nanoscopic process of substrate presentation. In agriculture and horticulture * Cellulose substrate * Expanded clay aggregate (LECA) * Rock wool * Potting soil * Soil In animal biotechnology Requirements for animal cell and tissue culture Requirements for animal cell and tissue culture are the same as described for plant cell, tissue and organ culture (In Vitro Culture Techniques: The Biotechnological Principles). Desirable requirements are (i) air conditioning of a room, (ii) hot room with temperature recorder, (iii) microscope r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spine-bellied Sea Snake
The spine-bellied sea snake (''Hydrophis hardwickii''), also commonly known as Hardwicke's sea snake and Hardwicke's spine-bellied sea snake, is a species of venomous sea snake in the family Elapidae. Etymology The specific name, ''hardwickii'', is in honor of English naturalist Thomas Hardwicke.Beolens, Bo; Watkins, Michael; Grayson, Michael (2011). ''The Eponym Dictionary of Reptiles''. Baltimore: Johns Hopkins University Press. xiii + 296 pp. . (''Lapemis hardwickii'', p. 116). Description ''H. hardwickii'' has the following characteristics. *Body short, stout, neck region not less than half as thick at midbody; *head large; scales squarish or hexagonal, juxtaposed, outer 3-4 rows larger than others, scale rows: males 23-31 around neck, females 27-35, around midbody, males 25-27, females 33-41; *ventrals small, usually distinct anteriorly, not so posteriorly, in males 114-186, in females 141-230; head shields entire, parietals occasionally divided; *nostrils superior, nasa ...

Thenus
''Thenus orientalis'' is a species of slipper lobster from the Indian and Pacific oceans. ''T. orientalis'' is known by a number of common names. The United Nations Food and Agriculture Organization prefers the name flathead lobster, while the official Australian name is Bay lobster. In Australia, it is more widely known as the Moreton Bay bug after Moreton Bay, near Brisbane, Queensland. In Singapore, both the flathead lobster and true crayfish are called crayfish. They are used in many Singaporean dishes. The species is sometimes confused with the Balmain bug (''Ibacus peronii'') but it can be distinguished by the placement of the eyes: the eyes of ''I. peronii'' are near the midline, while those of ''T. orientalis'' are at the margin of the carapace. ''T. orientalis'' has a strongly depressed body and grows to a maximum body length of , or a carapace length of . ''Thenus orientalis'' has an Indo-West Pacific distribution, ranging from the east coast of Africa (south ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
