Cuisine & Edibility

Discus

Not consumed — a prized ornamental aquarium fish known as the 'king of the aquarium' for its disc-shaped body and brilliant colors.

Great White Shark

Edible but rarely consumed; flesh requires careful handling to remove ammonia. Consumption is strongly discouraged — this species is Vulnerable and protected in many jurisdictions.

Species Overview

Discus

The discus is often called the 'King of the Aquarium' for its disc-shaped body and stunning color patterns. Native to the Amazon floodplains, it requires warm, soft, acidic water and feeds its fry with a mucus secretion from its skin.

Great White Shark

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.
