Yellowfin Tuna Cutaway Tee

Millions of years of R&D. Zero engineers. 🤙

The Fish Technology™ Yellowfin Tuna Cutaway Tee takes one of the ocean’s most ridiculous performance machines and breaks down the technology hiding underneath the skin.

From its oxygen-exchange system and hydrodynamic sensors to thermal management, red-muscle power, control surfaces, and lunate-tail propulsion, every part of a yellowfin exists for a reason.

The back graphic reimagines the yellowfin as an engineering schematic—complete with anatomical cutaway, numbered systems, technical callouts, multiple viewing angles, and the hardware responsible for turning a fish into an open-ocean missile.

Built by evolution. Perfected by the ocean.
