Similar to other puffer fishes, the silver-cheeked toadfish is extremely poisonous if eaten because it contains tetrodotoxin in its ovaries and to a lesser extent its skin, muscles and liver, which protects it from predators. This deadly substance causes paralysis of voluntary muscles, which may cause its victims to stop breathing or induce heart failure. Fatal intoxication's have been reported. Distributed in the Red Sea, Persian Gulf and Indo-West Pacific , this species is now one of the most invasive fish species for the Mediterranean sea. Egypt
