The nidarios to defend itself of, the buses with his cnidoblastos can cause injuries to the divers, that they include from a simple dermatitis to the same death. His effects will depend onthe species of nidarios and on the geographical region. The nidarios realize the breathing and the excretion for simple diffusion in any part of his corporal surface, his nervous system is of a very...
