Species Overview

Electric Eel

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.

Guppy

The guppy is one of the most widely distributed tropical fish, found in freshwater habitats across the Americas. Males display vivid colors and elaborate tail patterns to attract females. They are live-bearers, giving birth to free-swimming fry.
