Bonneviellidae
Bonneviellidae is a family of cnidarians belonging to the order Leptomedusae. The family consists of only one genus: ''Bonneviella'' Broch, 1909. It was named for Norwegian zoologist Kristine Bonnevie Kristine Elisabet Heuch Bonnevie (8 October 1872 – 30 August 1948) was a Norwegian biologist. She was the first woman to graduate with a science doctorate in Norway (and the second woman overall), Norway's first woman professor, a women's rights ... by then-doctoral student Hjalmar Broth in 1910.

Kristine Bonnevie
Kristine Elisabet Heuch Bonnevie (8 October 1872 – 30 August 1948) was a Norwegian biologist. She was the first woman to graduate with a science doctorate in Norway (and the second woman overall), Norway's first woman professor, a women's rights activist, and a politician for the Free-minded Liberal Party. Her fields of research were cell biology, cytology, genetics, and embryology. She was among the first women to be elected to political office in Norway. She suggested the epic voyage of her graduate student Thor Heyerdahl on the raft Kon-tiki, a voyage memorialized in the Kon-Tiki Museum, Oslo. Youth, primary, and secondary education She was the fifth of seven children born to Anne Johanne Daae (1839–1876) and her husband Jacob Aall Bonnevie (1838–1904), a member of the Norwegian parliament. She was baptized on 8 November 1872 at Vår Frue Church (Our Lady's Church) in Trondheim, part of the Church of Norway and previously Catholic. Anne died when Kristine was four, and ...

Leptomedusae
Leptothecata, or thecate hydroids, are an order of hydrozoans in the phylum Cnidaria. Their closest living relatives are the athecate hydroids, which are similar enough to have always been considered closely related, and the very apomorphic Siphonophorae, which were placed outside the "Hydroida". Given that there are no firm rules for synonymy for high-ranked taxa, alternative names like Leptomedusa, Thecaphora or Thecata, with or without the ending emended to "-ae", are also often used for Leptothecata. In the sessile stage, Leptothecata are surrounded by a chitinous outer layer as their exoskeleton, including the gonophores, their reproductive organ. Leptothecata exhibit radial symmetry, and their gonads can be found in the radial canals of the medusa stage. Their habits range from benthic to planktonic. The polyps and colonial forms are benthic, whilst the medusae are planktonic. Leptothecata exhibit extensive, complex variation. Thecata colonies also have extensive specializ ...

Cnidaria
Cnidaria ( ) is a phylum under kingdom Animalia containing over 11,000 species of aquatic invertebrates found both in fresh water, freshwater and marine environments (predominantly the latter), including jellyfish, hydroid (zoology), hydroids, sea anemones, corals and some of the smallest marine parasites. Their distinguishing features are an uncentralized nervous system distributed throughout a gelatinous body and the presence of cnidocytes or cnidoblasts, specialized cells with ejectable flagella used mainly for envenomation and capturing prey. Their bodies consist of mesoglea, a non-living, jelly-like substance, sandwiched between two layers of epithelium that are mostly one cell (biology), cell thick. Cnidarians are also some of the few animals that can reproduce both sexually and asexually. Cnidarians mostly have two basic body forms: swimming medusa (biology), medusae and sessility (motility), sessile polyp (zoology), polyps, both of which are radially symmetrical with mou ...
