I read this and it is true, as far as how poisonis it is im not sure, but... It was a warning.

to quote "This is not exactly pen ink. A variety of chemicals make up the defensive secretion, creating a multi-pronged attack. The ink targets the predator’s nervous system and messes with the creature’s behavioral control system."

Refrence, the complete marine aquarist, and some internet resorces.

This is a fact.
