Suprapedal Gland
The suprapedal gland or mucous pedal gland is an anatomical feature found in some snails and slugs. It is a gland located inside the front end of the foot of gastropods.Barker G. M. (2001) "Gastropods on Land: Phylogeny, Diversity and Adaptive Morphology." in Barker G. M. (ed.):The biology of terrestrial molluscs. CABI Publishing, Oxon, UK, . 1-146, cited page: page 12. The term ''suprapedal'' means "above the foot". The function of this gland is to produce mucus. The gland opens on the front end of the sole, on the ventral side of the foot. The mucus produced by this gland becomes a thin layer covering the sole of the foot, and this helps the gastropod in moving. There are gland cells in the suprapedal gland. For example, in the suprapedal gland of the land snail ''Pomatias elegans'' there are three types of gland cells: cells producing mucoproteins, cells producing proteins and cells producing sulphated mucopolysaccharides. For example, the land slug '' Leidyula floridana ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pseudunela Cornuta 5
''Pseudunela'' is a genus of minute sea slugs, acochlidians, shell-less marine (ocean), marine or temporary brackish or brackish gastropod mollusks in the clade Acochlidiacea. ''Pseudunela'' is the only genus in the family Pseudunelidae. ''Pseudunela'' is the type genus of the family Pseudunelidae. Taxonomy Pseudunelidae was placed within the superfamily Strubellioidea in the Taxonomy of the Gastropoda (Bouchet & Rocroi, 2005), taxonomy of Bouchet & Rocroi (2005). Pseudunelidae was subsequently placed within the (unranked) Hedylopsacea by Schrödl & Neusser (2010).Schrödl M. & Neusser T. P. (2010). "Towards a phylogeny and evolution of Acochlidia (Mollusca: Gastropoda: Opisthobranchia)". ''Zoological Journal of the Linnean Society'' 158: 124-154. . Species These are the different species in the genus ''Pseudunela'': * ''Pseudunela cornuta'' (Challis, 1970) - type species of the genus ''Pseudunela'', marine and temporary brackish * ''Pseudunela eirene'' Wawra, 1988 - The de ...
