The European flounder is oval-shaped. It normally grows to about 30cm in length; maximum weights of 31lbs have been recorded. The upper surface of the flounder is usually dull brown or olive in colour with reddish spots and brown blotches. The flounder can camouflage itself by changing colour to suit its background.
Swordfish are the sole member of their family, Xiphiidae. Swordfish commonly reach 3 m (9.8 ft) in length, and the maximum reported is 4.55 m (14.9 ft) in length and 650 kg (1,430 lb) in weight. They are found in oceans and seas globally. In some parts of the world swordfish are classified as endangered and conservation efforts are underway.
The bluefish is the only living species now included in the family Pomatomidae. Adult bluefish are typically between 20-60 cm long, with a maximum reported size of 120 cm and 14 kg. Adult bluefish are strong and aggressive, and live in loose groups. They are fast swimmers which prey on schools of fish and can attack in feeding frenzies even after they have eaten their fill. Because of this aggression, fishermen handle them with caution.
