متن کاملNew records for the shallow-water chiton fauna (Mollusca, Polyplacophora) of the Azores (NE Atlantic)
Published records, original data from recent field work on all of the islands of the Azores (NE Atlantic), and a revision of the entire mollusc collection deposited in the Department of Biology of the University of the Azores (DBUA) were used to compile a checklist of the shallow-water Polyplacophora of the Azores. Lepidochitona cf. canariensis and Tonicella rubra are reported for the first tim...
متن کاملFormation in Chrysochromulina Chiton
The normal form of the species has been compared with a deviant form and the processes of scale production in both more fully studied. The deviation is shown to be genetically based, possibly a mutation, of which the main structural expression is loss of capacity to develop the normal outer layer of material on each scale. The large scales also lack rims, a flange on the back giving a spurious ...
متن کاملTonicia atrata and Chiton cumingsii (Polyplacophora: Chitonidae): first records in European waters.
At present, over 300 species of marine alien Mollusca are reported from the European waters (Streftaris et al. 2005; Zenetos et al. 2010). However, only three alien polyplacophoran have been recorded: Chaetopleura angulata (Spengler, 1797), Acanthopleura gemmata (Blainville, 1825) and Chiton hululensis (E. A. Smith, 1903); the latter is considered as “questionable” (Zenetos et al. 2010). These ...
متن کاملThe Analysis of Neuromuscular Mechanisms in Chiton
1. The degree of curvature of the body and of the girdle of a Chiton is determined by the activity of antagonistic muscle groups. At a certain, early stage in the strychninization of a Chiton the reciprocal inhibition involved in the natural use of these muscle groups is reversed, such that extensor muscles, rather than, as normally, flexor muscles, contract as the result of stimulation. This c...
