Dear James (and others),
Being intertidal (and brackish/freshwater) herbivores I doubt that any
netires are rare. Some might be a little less common than others. Such a
species is probably Smaragdia tragena, which is never commonly encountered.
but to call it rare would be a gross overstatement.
My question to the group:
In several of the (previous) Archaeogastropods and related primitive
gastropods, such as the Neritidae, the large bulk of the species are from
shallow water. However, more recently species of these families have been
discovered from very deep water and abyssal depths beyond comprehension
(hydrothermal vents). This is especially the case in the Fissurellidae.
Does anyone know if any deep water Nerites have been discovered?
