Scaphandridae
Scaphandridae is a family (biology), family of sea snails, marine (ocean), marine gastropod mollusks in the superfamily Philinoidea. Taxonomy Scaphandridae was considered as a synonym of Cylichnidae in the Taxonomy of the Gastropoda (Bouchet & Rocroi, 2005), taxonomy of the Gastropoda by Bouchet & Rocroi, 2005). However, Malaquias et al. (2009)Malaquias M. A. E., Dodds J. M., Bouchet P. & Reid D. G. (2009). "A molecular phylogeny of the Cephalaspidea ''sensu lato'' (Gastropoda: Euthyneura): Architectibranchia redefined and Runcinacea reinstated".

Scaphander
''Scaphander'' is a genus of sea snails, marine (ocean), marine gastropod molluscs in the family (biology), family Scaphandridae, the canoe bubbles. Description (Described as ''Meloscaphander'') The shell is ovate, convex in its upper part, and tapers below, with a low, slightly exserted Spire (mollusc), spire. The Aperture (mollusc), aperture is large but shorter than the shell, and the Columella (gastropod), columella is moderately curved and thick. The surface is sculpted with rows of spiral pits. (Described as ''Scaphander (Sabatina)'' ) In most, if not all, species of this proposed subgenus, the callosity on the body does not form a distinct "fold." Instead, it appears as an amorphous mass, which sometimes may be granular, smooth, or occasionally tubercular in texture. While the typical fossil species seems to have an interiorly produced Callus (mollusc), callus, the recent species differ notably from Bellardi’s fossil. They not only lack the same callus characteristics ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
