Gonad characterization and reproductive cycle of Collisella subrugosa (Gastropoda: Acmaeidae

Shells (complete and fragments) with a maximum length of [greater than or equal to] 15 mm (and [greater than or equal to] 20 mm for Acmaeidae
and Patellidae) were considered of subsistence value and likely to have been purposefully collected by people.
nov.: a sibling species of limpet (Acmaeidae
) discovered by electrophoresis.
This was considered by Kiel to provide "further evidence for their position as sister group of the Acmaeidae
." My original observation (McLean 1990) was that the individual teeth of the radula of the Neolepetopsidae were unmineralized, considering that the teeth are not darkly opaque, as observed in the shallow-water patellogastropods.
A typical rocky shore setting might show the sequence Littorinidae, Acmaeidae
, Mytilidae, Ostreidae, Turbo, chitons, and Trochidae as the most conspicuous forms of mollusks from the splash zone (Engeman and Hegner 1981).
Shell size variation of Notoacmea biradiata (Archeogastropoda: Acmaeidae
) as a response to gastropod density and height in shore in the Colombian Pacific coast.
Best known among the groups that have mineralized teeth are the limpets (Gastropoda: Acmaeidae
, Patellidae) and chitons (Polyplacophora).
