A rare stranding event involving a 297 cm long mature male bluntnose sixgill shark (Hexanchus griseus) occurred on the Tuscan coast in the central Tyrrhenian Sea. The stranded specimen had 6 rows of teeth indicating that it belonged to the H. griseus and not to the Hexanchus nakamurai species, which only has 5. Biometric data on two teeth of the left front region of the lower jaw were collected. The body of the specimen did not show evidence of capture, only a deep cut at the height of the orbital arch suggesting a crash or the ramming of a boat.
