Hermodice Carunculata
''Hermodice carunculata'', the bearded fireworm, is a type of marine bristleworm belonging to the Amphinomidae family, native to the tropical Atlantic Ocean and the Mediterranean Sea. Description Bearded fireworms are usually in average length, but can reach up to . At first glance, this fireworm looks like a centipede with its elongated and flattened appearance, multiple segments, white silks, and parapodia and gills located on the side of its body. Its colors are varied and range from greenish, to yellowish, to reddish, grayish through white with a pearly glow. The body consists of 60 to 150 identical segments separated from each other by a thin white line and protected by cuticles. Each segment has a pair of parapodia, a structure for locomotion, clusters of stinging white bristles, and red or orange gills all in bilateral position. The anterior part of the worm can be recognized by small growths, called caruncle, which have the same color of the gills on the first fou ...

Hjalmar Kinberg
Johan Gustaf Hjalmar Kinberg (13 May 1820 – 29 August 1908) was a Swedish zoologist, physician and veterinarian who was born in Grönby, near Trelleborg, Skåne County and who died in St. Matthew's Parish, Stockholm. Family Hjalmar Kinberg's father was a rural dean, as was his grandfather, . His mother, Margareta Lovisa Schlyter, was the sister of Professor Carl Johan Schlyter, a noted Swedish lawyer and academic. Kinberg married twice, first, in 1854, to Helena Stockenberg (1831–1858). After the death of his first wife, he married again in 1859 to Aurore Hammarskjöld. He had two children: Arvid Gustaf Kinberg who was born in 1860 and Gottfrid Hilding Kinberg who was born in 1874. He is the great-great-grandfather of Anna Kinberg Batra, a Swedish politician who was Leader of the Moderate Party and Leader of the Opposition in Sweden. Career Kinberg enrolled at the University of Lund in 1838 and graduated with a degree in natural sciences in 1844, then a Master of Philoso ...

Annelids
The annelids (), also known as the segmented worms, are animals that comprise the phylum Annelida (; ). The phylum contains over 22,000 extant species, including ragworms, earthworms, and leeches. The species exist in and have adapted to various ecologies – some in marine environments as distinct as tidal zones and hydrothermal vents, others in fresh water, and yet others in moist terrestrial environments. The annelids are bilaterally symmetrical, triploblastic, coelomate, invertebrate organisms. They also have parapodia for locomotion. Most textbooks still use the traditional division into polychaetes (almost all marine), oligochaetes (which include earthworms) and leech-like species. Cladistic research since 1997 has radically changed this scheme, viewing leeches as a sub-group of oligochaetes and oligochaetes as a sub-group of polychaetes. In addition, the Pogonophora, Echiura and Sipuncula, previously regarded as separate phyla, are now regarded as sub-group ...

Amphinomidae
Amphinomidae, also known as the fireworms, bristle worms or sea mice, are a family (biology), family of marine polychaetes, many species of which bear chaetae mineralized with carbonate. The best-known amphinomids are the fireworms, which can cause great pain if their toxin-coated chaetae are touched or trodden on. Their relationship to other polychaete groups is somewhat poorly resolved. Complanine Complanine is a quaternary ammonium cation, quaternary ammonium salt that has been isolated from the marine fireworm ''Eurythoe complanata''. It causes an inflammatory effect upon contact with the skin or mucous membranes. It was previously known that handling the fireworm caused it to release a chemical that induces inflammation of the skin of marine predators and mammals (including humans). Complanine was the first compound isolated from the fireworm which causes these effects. It is presumed that this compound's function is to deter predators of the fireworm. Species ...

Cosmopolitan Distribution
In biogeography, a cosmopolitan distribution is the range of a taxon that extends across most or all of the surface of the Earth, in appropriate habitats; most cosmopolitan species are known to be highly adaptable to a range of climatic and environmental conditions, though this is not always so. Killer whales ( orcas) are among the most well-known cosmopolitan species on the planet, as they maintain several different resident and transient (migratory) populations in every major oceanic body on Earth, from the Arctic Circle to Antarctica and every coastal and open-water region in-between. Such a taxon (usually a species) is said to have a ''cosmopolitan'' distribution, or exhibit cosmopolitanism, as a species; another example, the rock dove (commonly referred to as a ' pigeon'), in addition to having been bred domestically for centuries, now occurs in most urban areas around the world. The extreme opposite of a cosmopolitan species is an endemic (native) species, or one foun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Errantia
Errantia is a diverse group of marine life, marine polychaete worms in the phylum Annelida. Traditionally a subclass (biology), subclass of the paraphyletic class Polychaeta, it is currently regarded as a monophyletic group within the larger Pleistoannelida, composed of Errantia and Sedentaria. These worms are found worldwide in marine environments and brackish water. Phylogeny The phylogeny of polychaetes is slowly being resolved. Errantia and Sedentaria are the two biggest clades of polychaetes, and together they compose clade Pleistoannelida. Two groups are nested within Errantia: Aciculata (Eunicida + Phyllodocida) and Protodriliformia (progenesis, small meiofaunal worms such as the Protodrilida). Historically, the order Amphinomida was part of this subclass. However, phylogenetic analyses place Amphinomida inside a basal clade with Sipunculida and ''Lobatocerebrum'', and this clade is the sister group to Pleistoannelida. Some taxon, taxa, such as Spintheridae and Myzostomida ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
