Sociality of sperm whale off Ischia Island (Tyrrhenian Sea, Italy)
1. The sperm whale (Physeter macrocephalus) is one of the eight species of cetaceans routinely encountered in the Mediterranean Sea; however, information on the social organization of sperm whales living in the basin remains scarce. 2. The social behaviour of sperm whales within female units, and gr...

The social behaviour of sperm whales within female units, and groups of males are reported, made over an 11-year period (2002–2012) in waters around the islands of Ischia and Ventotene (Tyrrhenian Sea, Italy), an area characterized by the presence of a submarine canyon system and a coastal marine protected area (‘Regno di Nettuno’ MPA). 3.
