Physonectae
Physonectae is a suborder of siphonophores. In Japanese it is called (). Organisms in the suborder Physonectae follow the classic Siphonophore body plan. They are almost all pelagic, and are composed of a colony of specialized zooids that originate from the same fertilized egg. While Physonectae are not generally well-known by the public, a related species also of the order Siphonophorae is the Portuguese man o' war, well-known for its painful sting. Distribution The majority of physonect siphonophores are pelagic, with the exception of Rhodallidae, which are a family of benthic physonects first collected during the ''Challenger'' expedition and described by Ernst Haekel in his ''Challenger'' monograph. Physonects, and siphonophores in general, are known to be widely distributed globally, but are understudied. Few individuals have been collected and are often misidentified. As a result, their exact global distributions are unclear. Morphology All physonect siphonophor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Siphonophore
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 lig ...

Apolemiidae
''Apolemia'' is a genus of siphonophores. It is the only genus in the monotypic family Apolemiidae. Despite appearing to be a single multicellular organism, they are actually a floating colony of polyps and medusoids, collectively known as zooids. Discovery The genus ''Apolemia'', named by Baltic-German physician and naturalist Johann Friedrich von Eschscholtz, was first documented in 1815 with the discovery and description of '' Apolemia uvaria'' (the "string jellyfish"), by French naturalist Charles Alexandre Lesueur off the coast of Europe. It was displaying a net-like feeding pattern in the pelagic zone, and was documented to have rows of nematocysts. Few species have been well-defined within the genus otherwise. Feeding ''Apolemia'' are carnivorous invertebrates, which have been documented to feed on small fish, crustaceans, copepods, other plankton, and even other siphonophores. They do so by extending long, curtain-like nematocyst rows into the water column, for prey to b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fanny Moser (scientist)
Fanny Moser, also known as Fanny Hoppe-Moser, (27 May 1872 - 24 February 1953) was a Swiss-German zoologist. Her father Johan-Heinrich Moser was an engineer and built the Moser dam in Schaffhausen. In 1896 Fanny Moser became the first female student to register at the University of Freiburg, where she studied medicine. She then began studying zoology in Munich and received her doctorate in 1902, specialising in the developmental history of the vertebrate lung. In 1903 she married the composer Jaroslav Hoppe. They moved to Berlin and Moser began her international research, which included identifying nine new species, most notably the cold-water southern physonect '' Pyrostephos vanhoeffeni'' that was collected from the South Pole expedition for the Museum of Natural History in Berlin. The prince of Monaco commissioned her to work on his zoological deep sea collection. She became involved with parapsychology Parapsychology is the study of alleged psychic phenomena (extrasenso ...
