Along the shifting floodplains of the Lower Mekong, Pao turgidus lives by rhythm rather than chase. It moves when the water moves and waits when it slows, blending completely with the riverbed until a flicker of motion betrays its prey.

The Leiodon cutcutia is one of the most remarkable yet underappreciated puffers in the aquarium world.
