Species Overview

Grand requin blanc

The great white shark is the world's largest predatory fish. Found in coastal surface waters of all major oceans, it can detect a single drop of blood in 100 liters of water. Despite its fearsome reputation, attacks on humans are rare.

Plecostomus

The common pleco is a large armored catfish native to South America. Often purchased as an algae eater, it can outgrow most home aquariums. Its sucker-like mouth allows it to rasp algae from surfaces and anchor itself in fast-flowing currents.
