Bluefin Tuna (Maguro) Coloring Page — Free Printable for Adults & Seniors

A bluefin tuna — maguro — drawn in profile: torpedo body, crescent tail and the stiff little finlets along its back. The color sample shows the dark metallic blue of the back shading into a silver belly, which makes it a satisfying subject for blending with colored pencils.

How fast can a bluefin tuna swim?

Very fast. Figures of 70 to 80 km/h are often quoted; carefully measured speeds usually come in lower, and that kind of pace is a short burst rather than a cruising speed. Bluefin also have to keep moving in order to breathe — they drive water over their gills by swimming, so they never really stop.

What is the difference between otoro, chutoro and akami?

Fat content. Otoro is the richest cut, from the belly; chutoro sits in between; akami is the lean red muscle along the back. The ranking has flipped over time: before refrigeration the fatty belly spoiled quickly and was little valued, and lean akami was the cut people wanted. Today otoro is the most expensive part of the fish.

Where is bluefin tuna caught?

It ranges across the open ocean in temperate and tropical waters of the Pacific, the Atlantic and the Indian Ocean. The well-known Japanese grounds lie off Mie and Shizuoka and in the seas off the Tohoku region. Wild bluefin is now fished under international catch limits, brought in to let the stocks recover.
