Pelagic. The Sunfish is the largest of the bony fishes. It feeds on jellyfish, plankton, squid, crustaceans, small fish...
➢ To spot it: usually alone and offshore; detectable with its dorsal fin appearing on the surface or its white silhouette floating like a large piece of plastic. In the latter case, it is not uncommon to see gulls directly on its body to rid it of parasites.
➢ To identify it: whitish disc-shaped body, dorsal and anal fins well back and opposite each other.

Wingspan: 78 - 90 cm
Surely one of the stars of Mor Braz, since we can find several hundred (even thousands) of individuals! This shearwater breeds only on the Balearic archipelago. Its population is estimated at about 20,000 individuals. The Morbihan waters play an important role in the migration and dispersal of this species considered to be in critical danger of extinction.
➢ To spot it: with binoculars, often low-flying
➢ To identify it: silhouette and shearwater (long wings kept straight, alternating series of hovers and wing beats); differs from the Manx Shearwater by its more "dirty", faded and low contrasting appearance (brown and dirty white).
