Haminoeoidea
Haminoeoidea is a taxonomic superfamily of small sea snails or bubble shells, marine opisthobranch gastropod mollusks in the clade Cephalaspidea, the headshield slugs and bubble snails. These cephalaspideans do have distinct anatomical and morphological characteristics, but unfortunately many species were described only from empty shells. For proper clarification of the taxonomy, those species still need the research necessary to provide a good description of the external and internal anatomy of the living animal. Description of live animal The soft parts of the animals can retract completely or partially into their shells, and yet this offers them scant protection, because the aperture is rather wide and there is no operculum. Furthermore, the shell is very fragile and can easily be crushed by a predator. The cephalic shield of most species in this superfamily has two hind lobes that lie back on the front of the shell. The black eyes are usually buried just beneath the surf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cephalaspidea
The order Cephalaspidea, also known as the headshield slugs and bubble snails, is a major taxon of sea slugs and bubble snails, marine gastropod mollusks within the larger clade Euopisthobranchia.Jörger K. M., Stöger I., Kano Y., Fukuda H., Knebelsberger T. & Schrödl M. (2010). "On the origin of Acochlidia and other enigmatic euthyneuran gastropods, with implications for the systematics of Heterobranchia". ''BMC Evolutionary Biology'' 10: 323. . Bubble shells is another common name for these families of marine gastropods, some of which have thin bubble-like shells. This clade contains more than 600 species. Members of this worldwide clade used to be considered the most primitive of the opisthobranchs, but now they are considered as derived and specialized members of the Euthyneura Spengel, 1881. Headshield slugs are the most morphologically diverse group of all the opisthobranchs. Anatomy The vast majority possess a shell, although it may be reduced or internal. They have ...

Bullacta Exarata
''Bullacta exarata'', common name the Korean mud snail, is a species of a sea snail or bubble snail, a marine gastropod mollusc in the family Haminoeidae, the bubble snails. ''Bullacta exarata'' is a commercially important mollusc which is used as a food item in eastern China. Taxonomy ''Bullacta exarata'' is the only species in the genus ''Bullacta''. cf. ''Bullacta'' is the type genus of the family Bullactidae Thiele, 1926, as shown in the taxonomy of the Gastropoda by Bouchet & Rocroi (2005). Based on phylogenetic genetic analysis by Malaquias (2010), ''Bullacta exarata'' should be placed in the family Haminoeidae. Distribution ''Bullacta exarata'' is endemic to coastlines of the South and East China Seas from Hainan to the Bohai Sea in north-eastern China, the western coast and south coast of Korea and Japan.Ye S.-F. & Lu J.-J.

Smaragdinellidae
Haminoeidae, commonly known as the haminoeid bubble snail family, is a taxonomic family of sea snails, marine opisthobranch gastropod mollusks in the superfamily Haminoeoidea. The name of this family has long been controversial, and used to be Atyidae or Atydidae. Another, but incorrect, spelling was Haminaeidae (See (ICZN) 2000. Opinion 1942). A number of genera have been proposed for this family, but the species are hard to identify (or sometimes impossible to identify) by looking only at the external characteristics. Until the internal anatomy of 'wet' specimens has been fully described, the status of many of the genera listed here is uncertain. Distribution These bubble snails occur in all warm or temperate seas. Habitat These are sand dwellers or they live on muddy bottoms, in bays, estuaries, and close to the shore in tidepools. Description of the live animal These are colorful snails, that can partially take the color of the sea floor. Their large cephalic shield is ro ...

Haminoea Cyanomarginata
''Haminoea'' is a genus of medium-sized sea snails or bubble snails, marine opisthobranch gastropod molluscs in the family Haminoeidae, the haminoea bubble snails, part of the clade Cephalaspidea, the headshield slugs and bubble snails.Bouchet, P.; Gofas, S. (2012). Haminoea. Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=138054 on 2012-06-06 Systematics Three different spellings (''Haminoea, Haminea, Haminaea'') were used for this genus over two hundred years. The ICZN finally made a decision that the correct spelling is ''Haminoea''. Oskars et al. (2019) restricted ''Haminoea'' to species from the Atlantic and eastern Pacific, and resurrected ''Haloa'' and '' Lamprohaminoea'' for Indo-Pacific species.Oskars, T. R. and M. A. E. Malaquias. 2019.

Sea Lettuce
The sea lettuces comprise the genus ''Ulva'', a group of edible green algae that is widely distributed along the coasts of the world's oceans. The type species within the genus ''Ulva'' is ''Ulva lactuca'', wikt:lactuca, ''lactuca'' being Latin for "lettuce". The genus also includes the species previously classified under the genus ''Enteromorpha'', the former members of which are known under the common name green nori. Description Individual blades of ''Ulva'' can grow to be more than 400 mm (16 in) in size, but this occurs only when the plants are growing in sheltered areas. A macroscopic alga which is light to dark green in colour, it is attached by disc holdfast. Their structure is a leaflike flattened thallus. Nutrition and contamination Sea lettuce is eaten by a number of different sea animals, including manatees and the sea slugs known as sea hares. Many species of sea lettuce are a food source for humans in Scandinavia, Great Britain, Ireland, China, and Japan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Johannes Thiele (zoologist)
Karl Hermann Johannes Thiele (1 October 1860 – 5 August 1935) was a German zoologist specialized in malacology. Thiele was born in Goldap, East Prussia. His ''Handbuch der systematischen Weichtierkunde'' (English edition published by the Smithsonian under the title ''Handbook of Systematic Malacology'') is a standard work. From 1904 until his retirement in 1925 he was the curator of the malacological collection at the Museum für Naturkunde (Museum of Natural History) in Berlin. Thiele described more than 1.500 new species of molluscs; until today their types are deposited with the Museum of Natural History in Berlin. Especially important are his works on the Mollusca of the First German Antarctica Expedition and of the German Deep Sea Expedition aboard the vessel Valdivia. Thiele's classification of Gastropoda has been in use up to the past decade. It modified an earlier concept of Henri Milne-Edwards (1848) with three subclasses: Prosobranchia, Opisthobranchia and Pulmonata. ...
