Continued sightings of bottlenose dolphins off the coast of Rome.

There have been numerous sightings of dolphins off Rome's coast in recent days, including a group of 25 dolphins, described as "exceptional" by Oceanomare Delphis Onlus.

The organisation is involved in the Delfini capitolini project which monitors and studies the presence of dolphins in the stretch of sea between Ostia and Fiumicino.

Oceanomare said the 25 bottlenose dolphins were filmed by fishermen who were able to provide experts with detailed information including photographs, acoustic recordings and exact coordinates.

The dolphins were sighted off the coast of Tenuta del Presidente, at Capocotta, to the south of Ostia, on 30 March.

Since then there have been additional sightings of a group of seven dolphins, including two mothers and babies.

Oceanomare said it was "fundamental" that the public continue to report sightings to assist experts in their ongoing research, according to Italian news agency ANSA.
