Some facts about tuna are:
  • Tuna are fast swimmers.
    Some species can swim up to 75 km/h or 47 mph.

  • Tuna are migratory fish.
    They travel long distances across the oceans, sometimes crossing from one continent to another.
    Some bluefin tuna can swim from North America to Europe.

Where does the Tuna live?

Tuna are a group of eight species of fish that belong to the Thunnini tribe.

Tuna are pelagic fish, meaning they live beyond the continental shelf in the open sea—not near coral reefs, the sea floor, or shoreline.

Tuna generally need to eat a lot and move a lot to sustain themselves.

Tuna have different habitat preferences depending on their species.

Some tuna have cosmopolitan ranges and live across nearly the entire globe.

Other tuna live only in specific regions.

As a whole, they utilize temperate and tropical seas and you can find various species throughout these regions.

Some tuna are also able to maintain their body temperature in a way similar to mammals.

Tuna swim incredible distances as they migrate.

Some tuna are born in the Gulf of Mexico and travel across the entire Atlantic Ocean to feed off the coast of Europe, and then swim all the way back to the Gulf to breed.

Tuna are also found in some freshwater habitats, such as coastal estuaries, lakes, wetlands, rivers, mountain streams and even alpine tarns.

However, these habitats are usually used by juvenile tuna or by some species that can tolerate low salinity levels.

Most tuna spend most of their lives in the open ocean, where they are adapted to survive and thrive.

What does the Tuna look like?

A tuna is a type of saltwater fish that belongs to the family Scombridae, along with mackerels.

Tunas have a sleek, streamlined body that allows them to swim fast and agilely.

They can reach speeds of up to 75 km/h (47 mph) in short bursts.

Tunas vary in size and color, depending on the species.

Some of the largest tunas are the Atlantic bluefin tuna, which can grow up to 4.6 m (15 ft) long and weigh up to 684 kg (1,508 lb), and the yellowfin tuna, which can reach 2.4 m (7.9 ft) and 200 kg (440 lb).

Tunas are usually dark blue or black on the back, and silver or white on the belly.

Some tunas have yellow or red stripes or spots on their sides.

Tunas have a distinctive feature called the corselet, which is a band of large, thick scales around the front part of the body.

Tunas are also known for their ability to maintain a higher body temperature than the surrounding water, which helps them stay active and efficient in cold or deep waters.
