| TUNA - One of the sea's most impressive creatures. A beautiful and powerful fish, it is well suited to a long life endlessly swimming the open seas. Unlike most fish species, which have white flesh, tuna have flesh that is pink to dark red.
They are true athletes of the ocean, one of the fastest ocean swimmers in the world. the side fins retract into special grooves
and the eyes form a smooth surface with the rest of the head in one of the most hydrodynamically advanced bodies in the
sea. They must keep moving so that water passes over their gills, carrying oxygen to the muscle system. The slowest a
tuna can swim safely to maintain the oxygen flow is to move its own length every second, faster than the fastest human
swimmer at top speed.
