Abstract

KANAGUSUKU, Keny; ROMERO, Miguel  and  RAMIREZ-AMARO, Sergio. Multiple morphological abnormalities in a blue shark Prionace glauca (Linnaeus, 1758) embryo from the Peruvian coast, southeast Pacific. Lat. Am. J. Aquat. Res. [online]. 2020, vol.48, n.1, pp.141-145. ISSN 0718-560X.  http://dx.doi.org/10.3856/vol48-issue1-fulltext-2317.

This study reports for the first time a case of multiple morphological abnormalities in a blue shark Prionace glauca embryo collected on the Peruvian coast, southeast Pacific. External exploration and radiograph picture showed duplicated parts in the cephalic region (mouths and eye sockets) and trunk anomalies (thoracic lordosis and rolled caudal fin). The duplicate face parts in a single head seen in the embryo, suggest a diprosopia anomaly.

Keywords : Prionace glauca; blue shark; abnormalities; deformity; malformation; teratology; Peru.
