Agalma is a genus of siphonophores in the family Agalmatidae. Siphonophores are colonial hydrozoans that feed on zooplankton. [2]
The Portuguese man o' war, also known as the man-of-war or bluebottle, is a marine hydrozoan found in the Atlantic Ocean and the Indian Ocean. It is considered to be the same species as the Pacific man o' war or bluebottle, which is found mainly in the Pacific Ocean. The Portuguese man o' war is the only species in the genus Physalia, which in turn is the only genus in the family Physaliidae.
Johann Friedrich Gustav von Eschscholtz was a Baltic German physician, naturalist, and entomologist. He was one of the earliest scientific explorers of the Pacific region, making significant collections of flora and fauna in Alaska, California, and Hawaii.
Siphonophorae is an order within Hydrozoa, which is a class of marine organisms within the phylum Cnidaria. According to the World Register of Marine Species, the order contains 175 species described thus far.
An agalma is a cult image or votive offering.
Marrus orthocanna is a species of pelagic siphonophore, a colonial animal composed of a complex arrangement of zooids, some of which are polyps and some medusae. Swimming independently in the mid-ocean, it lives in the Arctic and other cold, deep waters. It is a colonial creature that is born from a single egg which is fertilized. Later on, a protozoan forms that eventually grows to form more duplicating members of the colony. It belongs to the order Siphonophorae and the genus Marrus, which also includes M. antarcticus, M. claudanielis, and M. orthocannoides.
Agalmatidae, or Agalmidae, is a family of siphonophores.
Eucnemidae, or false click beetles, are a family of elateroid beetles including about 1700 species distributed worldwide.
Apolemia is a genus of siphonophores. It is the only genus in the monotypic family Apolemiidae.
Passalus is a genus of beetles of the family Passalidae.
Dendrogramma enigmatica is a species of siphonophore, the only one in its genus. It has been first described in 2014 on the basis of its morphology from a collection of specimens gathered in 1986. Its taxonomic affinity among animals was then unclear, but RNA from new specimens in 2016 allowed it to be identified as a siphonophore by barcoding and phylogenomics. The specimens are presumed to represent parts (bracts) of an entire siphonophore that has not been identified yet.
The Diphyidae are a family of siphonophores. These are colonial siphonophores with two nectophores arranged one behind the other. The front one includes a somatocyst, while the hind one does not. The somatocyst often contains an oil droplet for buoyancy control. A nectosac in each nectophore allows the organism to swim efficiently.
Bathyphysa conifera, sometimes called the flying spaghetti monster, is a bathypelagic species of siphonophore in the family Rhizophysidae. It is found in the northern Atlantic Ocean and off the coast of Southwestern Africa and California.
Agalma elegans is a species of siphonophores in the family Agalmatidae. It has been found in a wide variety of locations, including between the Reloncavi Fjord and the Boca del Guafo Passage, in the Chiloe Inland Sea (CIS), Chile.
Lebiini is a tribe of ground beetles in the family Carabidae. There are more than 250 genera and 4,800 described species in Lebiini.
Limonius is a genus of click beetles in the family Elateridae. Many of the species formerly placed in this genus have been removed to other genera such as Gambrinus.
Agrypninae is a subfamily of click beetles in the family Elateridae. There are at least 130 genera and more than 430 described species in Agrypninae.
Physonectae is a suborder of siphonophores. In Japanese it is called 胞泳.
Calycophorae is a suborder of Siphonophores alongside two other suborders Physonectae and Cystonectae. This suborder includes the giant siphonophore, ; one of the longest lengthwise extant creatures (40–50m). While the Physonectae have a pneumatophore, nectophore, and a siphosome, Cystonectae lack a nectophore, and Calycophorae lack a pneumatophore. From the bell-shaped nectophores, Physonectae and Calycophorae are called Codonophores or Greek for bell-bearers. The distribution, morphology, and behaviors of Calycophorae species are vast and greatly depend on the species. Calycophoraes typically consist of two nectophores with a siphosome that have many tentacles that grow out of the siphosome. The Calycophoraes move by propelling water out of the nectophore much like how jellyfishes move. The tentacles act as fishing nets where the nematocysts on the tentacles paralyze their prey which are then later fed on. Calycophorae have three life stages, which are the larval development stage, the polygastric stage, and the eudoxid maturation stage. Each Calycophorae colony forms from one fertilized egg.
Agalma okeni is a species of siphonophore in the family Agalmatidae. It was first described by Johann Friedrich von Eschscholtz , who collected it on his second voyage. It was described again by James Dwight Dana in 1859, who named it Crystallomia polygonata.
Physophoridae is a family of siphonophores.
