Today’s survey at Liri Beach focused on the common stingray (Dasyatis pastinaca). These rays spend the day resting on the sandy seabed, sometimes half buried with only their eyes and spiracles visible. Careful observation helps us note their abundance and distribution along the coast, building a clearer picture of how they use this habitat.

As part of the survey, we also checked inside one of the sea caves near the beach. We already know that these caves are used by Mediterranean monk seals (Monachus monachus), so we entered with caution. In the middle of the cave, a male seal suddenly appeared and swam directly toward us.

We immediately stopped and decided not to continue further inside, respecting the possibility that more seals might be resting deeper within. Instead, we followed the male as he swam out of the cave. We later named him Nereus, after the old sea god of Greek mythology, a fitting name for such a rare and extraordinary animal.

This unexpected encounter was a reminder of how precious these habitats are. Liri Beach is not only a refuge for stingrays but also a sanctuary for one of the world’s most endangered marine mammals. Respecting their space ensures that these incredible animals can continue to thrive alongside us.
