Also known as gladiator fish (scientifically “Xiphias gladius”), the swordfish is characterized by its long, flattened, sword-shaped mouth which it uses as a weapon to defend itself against predators (killer whales, jacks) and to beat its prey. It can reach 5 meters in length and weigh more than 540 kilograms, with females being larger. In both cases, the trunk is bluish black and the belly is silver. It is a solitary fish -it does not group in schools of fish- and reaches high speeds to obtain food (tuna, hake, flying fish).

Curiosities
The swordfish prefers temperate waters and areas where the outside temperature exceeds 15 degrees Celsius, although it is a migratory species and, on occasions, it has been seen in cold waters. This is possible because it is ectothermic and has the ability to raise the temperature of its eyes and brain to maintain its body heat and see better.
