Castillo & Pequeño (1998) dealt with the morphological differences between the species of Helcogrammoides genus, however, the distribution of the characters may obscure the quality of the diagnosis; therefore, to evaluate the morphological characters (morphometric and meristic) through multivaria...

The present study provides new documented cases of abnormalities on chitons (hypomerism and coalescence of shell plates), in addition to four new cases on keyhole limpets (closed apical opening), and one new teratologic case on internal organs in octopuses (missing gill). We assess the frequency ...

Mollusk freaks: New teratological cases on marine mollusks from the south pacific ocean
According to the vicariant hypothesis proposed by Brakoniecki (1986) the closure of the Sea of Tethys and the opening of the Atlantic Ocean would play an important role in the history of squids of the family Loliginidae, which is reflected in its current neritic distribution. Our study evaluated ...
