ZALESKI, Tânia; PEREZ, José A. Angel  e  GANDARA-MARTINS, Ana luiza. Morphological and morphometric variability of the squid Lolliguncula brevis (Mollusca: Cephalopoda) in Brazilian waters: evidence for two species in the western atlantic?. An. Acad. Bras. Ciênc. [online]. 2012, vol.84, n.4, pp.1015-1028. ISSN 0001-3765.  http://dx.doi.org/10.1590/S0001-37652012000400016.

Morphological and morphometric variability of the small-sized coastal squid Lolliguncula brevis was assessed along the largest part of its latitudinal range in the southern hemisphere, off the Brazilian coast (8º S - 27º S). A general homogeneity in form was found throughout the entire latitudinal range. In terms of body proportions, no latitudinal gradients were evident, but a few local "morphotypes" could be distinguished. The distinctive egg mass morphology, and size and form features, including a hectocotylus 20-40% longer than the opposing ventral arm and the presence of suckers on the buccal membrane, indicated that Lolliguncula from northern and southern hemispheres might comprise two different taxa.

Palavras-chave : cephalopods; morphology; Loliginidae; Brazil.
