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 three life ...

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 li ...

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.

Diphyidae
The Diphyidae are a family of siphonophores. These are colonial siphonophores with two nectophores (swimming bells) arranged one behind the other. The front one includes a somatocyst (extension of the gastrovascular system), while the hind one does not. The somatocyst often contains an oil droplet for buoyancy control. A nectosac (central cavity with muscular walls) in each nectophore allows the organism to swim efficiently. Systematics The World Register of Marine Species includes the following taxa in the family Diphyidae: *Subfamily Diphyinae Quoy & Gaimard, 1827 ** Genus '' Chelophyes'' Totton, 1932 *** ''Chelophyes appendiculata'' (Eschscholtz, 1829) *** ''Chelophyes contorta'' (Lens & van Riemsdijk, 1908) ** Genus '' Dimophyes'' Moser, 1925 *** ''Dimophyes arctica'' (Chun, 1897) ** Genus '' Diphyes'' Cuvier, 1817 *** ''Diphyes antarctica'' Moser, 1925 *** ''Diphyes bojani'' (Eschscholtz, 1825) *** ''Diphyes chamissonis'' Huxley, 1859 *** ''Diphyes dispar'' Chamisso & Ey ...

Karl Georg Friedrich Rudolf Leuckart (7 October 1822 – 22 February 1898) was a German zoologist born in Helmstedt. He was a nephew to naturalist Friedrich Sigismund Leuckart (1794–1843). Academic career He earned his degree from the University of Göttingen, where he was a student of Rudolf Wagner (1805–1864). Afterwards he participated on a scientific expedition to the North Sea for the study marine invertebrates. Later he became a professor of zoology at the University of Giessen (1850) and the University of Leipzig (1869).ADB: Leuckart, Rudolf @ ''''.

Morphology (biology)
Morphology is a branch of biology dealing with the study of the form and structure of organisms and their specific structural features. This includes aspects of the outward appearance (shape, structure, colour, pattern, size), i.e. external morphology (or eidonomy), as well as the form and structure of the internal parts like bones and organs, i.e. internal morphology (or anatomy). This is in contrast to physiology, which deals primarily with function. Morphology is a branch of life science dealing with the study of gross structure of an organism or taxon and its component parts. History The etymology of the word "morphology" is from the Ancient Greek (), meaning "form", and (), meaning "word, study, research". While the concept of form in biology, opposed to function, dates back to Aristotle (see Aristotle's biology), the field of morphology was developed by Johann Wolfgang von Goethe (1790) and independently by the German anatomist and physiologist Karl Friedrich Burdach ...
