From the Greek halios (marine) and otos (ear), abalones, genus Haliotis, were first mentioned [approximately equal to] 2,500 years ago by Aristotle, who wrote of "the wild limpet (called by some the 'sea ear')." In D'Arcy Thompson's translation of Aristotle, he notes that "wild limpet" is "commonly attributed to Fissurella

SUMMARY: This study describes the microscopic anatomy of the reproductive systems of the keyhole limpets Fissurella
latimarginata and Fissurella
cumingi to test the existence of a possible isolating reproductive mechanism of morphophysiological type between species, and consequently to determine if the findings provide a valid taxonomic characteristic to distinguish these sympatric species.
Of 49 species compared quantitatively, only four species changed significantly over 3 yr, including two southern species (the snail Pseudomelatoma torosa, which increased, and the limpet Fissurella
volcano, which decreased), and two cosmopolitan species (the snail Homalopoma luridum, which decreased, and the limpet Lottia asmi, which increased).
