Abylidae
The Abylidae are a family of marine invertebrates in the order Siphonophorae. They are colonial, but the colonies can superficially resemble jellyfish; although they appear to be a single organism, each specimen is actually a colony of Siphonophora. It contains the following taxa: * Subfamily Abylinae L. Agassiz, 1862 ** Genus '' Abyla'' Quoy & Gaimard, 1827 *** '' Abyla bicarinata'' Moser, 1925 *** '' Abyla haeckeli'' Lens & van Reimsdijk, 1908 *** '' Abyla trigona'' Quoy & Gaimard, 1827 ** Genus '' Ceratocymba'' Chun, 1888 *** '' Ceratocymba dentata'' (Bigelow, 1918) *** '' Ceratocymba leuckarti'' (Huxley, 1859) *** '' Ceratocymba sagittata'' Quoy & Gaimard, 1827 * Subfamily Abylopsinae Totton, 1954 ** Genus ''Abylopsis'' Chun, 1888 *** ''Abylopsis eschscholtzi ''Abylopsis'' is a siphonophore genus in the Abylidae.

Description / Behavior Abylopsis tetragona is a species of siphonophores in the family Abylidae.

Both facets are less regularly pentagonal. ''A. Tetragona'' has radial symmetry and has two basal teeth. This species has an exoskeleton of chitin and are almost entirely marine. The ''A. Tetragona'' has two body forms; a polyp and a medusa. All Hydrozoans have many cells that can form into two tissue types: Epidermis and gastrodermis. ''Abylopsis Tetragona'''s commo ...

Bassia Bassensis
''Bassia'' is a monotypic siphonophore genus in the family Abylidae. The genus contains the single species ''Bassia bassensis''. Description The species reaches body lengths of 6–8 cm. The body plan is radially symmetric around a central mouth, with a polyhedral shape bearing 4 main ridges which end in short basal teeth. The species is bioluminescent and has a bluish tint on the ridges of the nectophores and is covered in gelatinous sheets that form a “box” around the mouth. As in all cnidarians, there is a single gastrovascular cavity (the coelenteron) and the mouth acts as both mouth and anus; it is surrounded by a layer of tentacles bearing nematocysts. Distribution ''Bassia bassensis'' is common in warmer and tropical waters in the Atlantic and Pacific oceans, specifically around the African and Asian coasts. It is common in the Humboldt Current system, along with other gelatinous zooplankton off the coast of South America, where three currents mix togeth ...

Calycophorae
Calycophorae is a suborder of Siphonophores alongside two other suborders Physonectae and Cystonectae. This suborder includes the giant siphonophore, ('' Praya dubia''); one of the longest lengthwise extant creatures (40–50m). While the Physonectae have a pneumatophore (a float), nectophore (or nectosome), 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 thre ...

Description A wide anterior nectophore with side ridges creates a wing like appearance and providing wing functions. They are also have rounded edges of facets. There is no transverse ridge between the ventral and apico-ventral facets. On the posterior side the nectophore is both the same width and length reinforcing the round and wing shape. They have combs that contain between 4 and 7 strong ostial teeth. Distribution The species has been found off the southeast coast of Hawaii at depths below 1000 m during the summer months. It was also spotted off the coast of California at 200 m. Individuals were found in the South China Sea duri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Abyla (cnidarian)
''Abyla'' is a genus of colonial siphonophore in the subfamily Abylidae and the suborder Calycophorae. The genus contains three species and was established by Quoy and Gaimard in 1827. Taxonomy Three species are currently recognized: A number of former species in the genus have since been synonymized to these three species. Distribution and habitat All species in the genus are strictly marine, inhabiting mostly the pelagic zone The pelagic zone consists of the water column of the open ocean, and can be further divided into regions by depth (as illustrated on the right). The word ''pelagic'' is derived . The pelagic zone can be thought of as an imaginary cylinder or w .... They are mainly found in tropico-equatorial and subtropic regions.

Siphonophorae
Siphonophorae (from Greek ''siphōn'' 'tube' + ''pherein'' 'to bear') 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 thus far. Although a siphonophore may appear to be an individual organism, each specimen is in fact a colonial organism composed of medusoid and polypoid zooids that are morphologically and functionally specialized. Zooids are multicellular units that develop from a single fertilized egg and combine to create functional colonies able to reproduce, digest, float, maintain body positioning, and use jet propulsion to move. Most colonies are long, thin, transparent floaters living in the pelagic zone. Like other hydrozoans, some siphonophores emit light to attract and attack prey. While many sea animals produce blue and green bioluminescence, a siphonophore in the genus '' Erenna'' was only the second life form found to produce a red ligh ...
