Fissurella

The American province has also sent here representative species; for there is a Galapageian species of Monoceros, a genus only found on the west coast of America; and there are Galapageian species of Fissurella and Cancellaria, genera common on the west coast, but not found (as I am informed by Mr.

From the 181 specimens of Fissurella latimarginata examined, only one of them (0.55%) collected at El Frances, Coquimbo, in January of 2013, showed morphological abnormalities (Table 1).

Cada vez que lo acompane a orillar, antes de irnos arreglaba la carga de la jornada sobre su bicicleta, metia los pulpos (Octupus mimus) en un recipiente, acomodaba el chinguillo con las lapas (Fissurella ssp.) y partiamos a Cobija.

The effect of human exclusion on the population structure of keyhole limpets Fisurella crassa and Fissurella limbata on the coast of central Chile.

Type species Fissurella salebrosa Reeve, 1850, by original designation.

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 graecea ...

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).
