Puffer Fish
Is is clear from a recent study that the power of inflating has dramatic effects on blood circulation (due to the increased internal pressure) and on digestion (due to the stomach change in volume), and it is therefore the last resource, that a puffer fish can use for a limited number of times (7 to 12), to avoid death. For this reason we invite all the divers to not provoke puffer fish "inflation": this means a useless stress for the fish, that significantly reduces its life span.
