Cuisine & Edibility
Arapaima
Large, firm white fillets with a mild, clean flavor and low fat; historically a staple protein in Amazonian communities. Often salted and dried; sustainable harvest is tightly regulated.

Species Overview
Arapaima
The arapaima is one of the largest freshwater fish in the world, reaching up to 4.5 meters. An obligate air-breather, it must surface every 10-20 minutes to gulp air. Its tongue is bony and used to crush prey against the roof of its mouth.
Clownfish
The ocellaris clownfish is a protandrous sequential hermaphrodite that lives in a mutualistic relationship with sea anemones. Its mucus coating protects it from anemone stings. All individuals are born male and the dominant fish transitions to female.
