The Spotted sea hare, Aplysia dactylomela, is a species of large sea slug, a marine opisthobranch gastropod in the family Aplysiidae, the sea hares.
As traditionally defined, this species of sea hare was cosmopolitan, being found in almost all tropical and warm temperate seas, including the Mediterranean Sea where first seen in 2002 and likely self-established due to increasing temperatures.
We met the Red Squirrelfish (Sargocentron rubrum) in the sea of Cyprus while snorkelling among the rocks of the island. We did not expect to have this meeting in the Mediterranean because it is a tropical fish present in all tropical seas and in particular in the Indian Ocean and the Pacific Ocean. The reason for this sighting, as indeed for other tropical species now present in the Mediterranean, we owe it to the climatic warming of the sea, which creates favorable conditions, and to the Lessepsian migration: that is, to the entry and stabilization of animal and tropical species from the Channel of Suez.
