How to recognize the reticulated pufferfish ?

This species belongs to the group of pufferfish. These fish are nicknamed like this because they have the ability to inflate themselves when they feel threatened.

To achieve this inflation, they swallow water and fill their stomach to more than double their volume. This is made possible by their stretchy skin. This subterfuge makes them look much more impressive to their predators. They are also much more complicated to swallow. This change in shape becomes a disadvantage for these fish that, once inflated, can hardly move.

The reticulated pufferfish measures between 35 and 45 cm. This fish is bicolore with a predominantly blanc and gris body. The also has blanc ponctuations.
