Physonectae
Physonectae is a suborder of siphonophores. Organisms in the suborder Physonectae follow the classic Siphonophorae, Siphonophore body plan. They are almost all pelagic, and are composed of a colony of specialized zooids that originate from the same fertilized egg. Distribution The majority of physonect siphonophores are pelagic, with the exception of Rhodaliidae, Rhodallidae, which are a family of benthic physonects first collected during the Challenger expedition, ''Challenger'' expedition and described by Ernst Haeckel, 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 siphonophores have an Anatomical terms of location, aboral, apical pneumatophore filled with gas, which is formed by invagination of the superficial cell l ...

Siphonophorae
Siphonophorae (from Ancient Greek σίφων (siphōn), meaning "tube" and -φόρος (-phóros), meaning "bearing") is an order within Hydrozoa, 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. Siphonophores are highly polymorphic and complex organisms. Although they may appear to be individual organisms, 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 biolumines ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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. Research history 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. In 2020 researchers working off the coast of Western Australia came across an ''Apolemia'' which had coiled itself into a spiral form. The outer "ring" was estimated to be 47 meters (154 feet) long, with an estimated total length of 119 meters (390 feet). Thi ...

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 (extrase ...
