Seriola dumerili, commonly known as the greater amberjack was sighted in Guernsey. This is the first recording of this fish in Guernsey and it is uncommon to Britain. Seriola dumerili are blue or greenish in adults with a silvery white belly and sides. Sometimes, they have a brown or pinkish tinge. The juveniles are between 2 and 17 cm in length and have five dark body bars which split vertically across their body. The maximum recorded size for Seriola dumerili is 188 cm in length although it is common for them to grow up to 110 cm. The greater Amberjack is carnivorous and feed on other fishes and some invertebrates.
