Balanus Hohmanni
''Balanus'' is a genus of barnacles in the family Balanidae of the subphylum Crustacea. This genus is known in the fossil record from the Jurassic to the Quaternary periods (age range: from 189.6 to 0.0 million years ago.). Fossil shells within this genus have been found all over the world. Description The bodies of these organisms are totally enclosed by a stony gray-whitish shell. The size of these shells ranges from 5 millimeters to 10 centimeters. They take the form of a cone consisting of six plates fixed on the rocks. The active animal can only be observed within the water when the shell opens and the barnacles expose two branched appendages (cirri ) regularly hitting the water to catch food. They mainly feed on plankton. Habitat These barnacles can be found in coastal areas at low shallow depth, although they can also be seen living out of the water. They commonly colonize stones, rocks and shells. They are found in abundance on the shells of mussels. Species Species w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Balanus Glandula
''Balanus glandula'' (North American Acorn Barnacle, Common Acorn Barnacle) is one of the most common barnacle species on the Pacific coast of North America, distributed from the U.S. state of Alaska to Bahía de San Quintín near San Quintín, Baja California. They are commonly found in the upper intertidal zone on mussels, rocks and pier pilings. They can obtain oxygen from both water and air. This acorn barnacle is a moderate-sized one with a diameter of up to . The shell is formed by overlapping plates and has a calcareous basis. It has more the shape of a cylinder than the shape of a cone. The white operculum has heavily ridged walls. It can live up to ten years. It has been intensely studied in recent years as a model species for linking physical oceanography and population genetics (or phylogeography) surveys. This species was introduced to the shores of Argentina in the 1960s, and has become an invasive species An invasive species otherwise known as an alien is an ...

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 ...

Balanus Crenatus
''Balanus crenatus'' is a species of acorn barnacle in the Balanidae family. It is found in the North Pacific and the North Atlantic Ocean. Description The shell of ''B. crenatus'' is made of six calcareous plates and grows up to across. The upper edge of the plates are toothed and the shell is often tilted to one side. The opercular aperture is diamond shaped and protected by two further plates which can slide across when the animal is not feeding. Distribution This is a boreal species distributed in intertidal and sublittoral zones of the North Pacific and the North Atlantic. It has a similar distribution to '' Balanus balanus'', a species with which it is often associated. Biology This barnacle is a hermaphrodite and the reproductive organs develop during the winter. Individuals in a group fertilise each other and, after a period of maturation, nauplii are liberated into the water. After a number of moults, the larvae settle out of the zooplankton in about April and attach t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
