Ichthyohemotoxin

The 1904 article by Gley on the toxic action of the serum of the torpedo Torpedo marmorata was noteworthy in that the author reported ichthyohemotoxins were not limited to eels, but were widely distributed in fishes.

Poisonings with ichthyohemotoxins are very rare because eel blood is perorally toxic only in large quantities.

These same eels also possess an ichthyohemotoxin that is resistant to drying but can be destroyed by heating to greater than 65°C (149°F).
