Jassa is a genus of amphipods in the family Ischyroceridae, comprising the following species:
In embryogenesis, Rathke's pouch is an evagination at the roof of the developing mouth in front of the buccopharyngeal membrane. It gives rise to the anterior pituitary (adenohypophysis), a part of the endocrine system.
Lottia is a genus of sea snails, specifically true limpets, marine gastropod mollusks in the subfamily Lottiinae of the family Lottiidae, one of the families of true limpets.
Palaemon is a genus of caridean shrimp of the family Palaemonidae. The conventional circumscription of the genus Palaemon is probably paraphyletic. Molecular data suggest that Palaemonetes, as well as the genera Exopalaemon and Couteriella, are nested within Palaemon. Phylogenetic affinities in these groups correspond better with geographical origin than conventional genus assignments.
Edwardsia is a genus of sea anemones, the type of the family Edwardsiidae. They have eight mesenteries and live in tubes in the sand. The name, in New Latin, commemorates the French zoologist Henri Milne-Edwards.
Notoacmea is a southern genus of true limpets, marine gastropod molluscs in the subfamily Lottiinae of the family Lottiidae, the true limpets.
Acmaea is a genus of sea snails, specifically true limpets, marine gastropod mollusks in the family Acmaeidae, one of the families of true limpets.
Idotea is a genus of isopod crustaceans, mostly from cold temperate waters. The taxonomy of the genus is still in doubt, and many of the currently recognised species may be taxonomic synonyms, and others may be moved to different genera. The genus Idotea includes the following species:
Iphimedia is a genus of amphipods which belongs to the family Iphimediidae in the arthropod group Amphipoda. It is the only genus of the family to have species which live in tropical waters. All other genera of the family are only found in cold or deep oceans.
Tectura is a genus of small to medium-sized sea snails, true limpets, marine gastropod mollusks in the family Lottiidae.
Palaemon adspersus, commonly called Baltic prawn, is a species of shrimp that is frequent in the Baltic Sea, and is the subject of fisheries in Denmark. It is up to 70 mm (2.8 in) long, and lives in Zostera beds.
Praunus is a genus of mysid shrimp, comprising three species:
Jens Rathke was a Norwegian professor, scientist and zoologist.
Scalibregma inflatum, also known as T headed worm, is a burrowing marine polychaete. It is a cosmopolitan species that can be found from the Arctic to Antarctica, although most probably several species are confounded.
Pycnodontidae is an extinct family of ray-finned fishes, ranging from the Triassic period until the Eocene.
Dendrodoa is a genus of ascidian tunicates in the family Styelidae.
Phyllodocidae is a family of polychaete worms. Worms in this family live on the seabed and may burrow under the sediment.
Trirhabda is a genus of skeletonizing leaf beetles in the family Chrysomelidae. There are more than 30 described species in Trirhabda. They are found in North America and Mexico.
Brada is a genus of polychaetes belonging to the family Flabelligeridae.
