Endophallus: membranous (0), or radular
or with sclerites (1).
Many subsequent authors perpetuated Lamarck's misidentification, until Clench and Turner (1964) described the radular
morphology and properly distinguished both taxa.
Diffferentiation in radular
and embryonic characters, and further comments on gene flow, between two sympatric morphs of Littorina saxatilis (Olivi).
52); m9a, much more developed, about as wide as m4, broadly covering radular
nucleus (Figs 52, 53).
Distribution and radular
morphology of various nudibranchs (Gastropoda: Opisthobranchia) from the Gulf of California.
In GKL with an SL of ~2 mm, the teeth are larger, the rachidian tooth no longer has a triangular tip and lies flat along the radular
ribbon except for a curled cusp.
I use the term buccal mass to refer to both the buccal cavity and the radular
teeth, and the muscles and sometimes cartilages that facilitate functioning of the radular
Patterns of radular
tooth structure in carnivorous land snails.
To test the hypothesis that Choneplax lata was the source of the grazing, we compared the mosaic pattern of scars on Porolithon pachydermum with the radular
morphology of C.
For any species of gastropod, the length of radular
ribbon will be a result of a dynamic balance between the production of rows of teeth verses the wear and shedding of older teeth (Runham & Thornton 1967, Padilla et al.
Two neurons of the buccal ganglia, which innervate radular
tensor muscle groups (Kater, 1974; Zoran et al, 1989), were primarily used for these studies: buccal neurons B19 and B110.
