Poisonous fish found in Greek waters

Experts are warning against the consumption of exotic fish following the discovery off the coasts of the Peloponnese and Halkidiki in northern Greece of the poisonous Red Sea puffer fish.
The fish, which enter the Mediterranean via the Suez Canal, have a gray lower body and black spots on the upper body, and range in length from 10 to 30 centimeters.
Their skin and internal organs contain a toxin that paralyzes the nervous and respiratory systems.
