Species Overview

Aguja azul

The blue marlin is the pinnacle of big-game fishing. Found in tropical and temperate Atlantic and Indo-Pacific waters, it can exceed 500 kg and is known for spectacular aerial displays when hooked.

Despite its name, the electric eel is not a true eel but a knifefish. It can generate electrical discharges of up to 860 volts to stun prey and defend itself. About 80% of its body is dedicated to three electric organs.
