SAQ 1054 – Toxicology – coastal child after rock pool exposure

A 4-year-old boy in a small coastal town cried out while playing in a rock pool and said an octopus bit him. He then developed vomiting.

Twenty minutes later he is obtunded, centrally cyanosed, has HR 53 with weak central pulse only, no reliable saturation trace, no spontaneous breathing, GCS 3 and fixed dilated pupils. You successfully intubate him.

Name one toxin produced by this octopus and state its mechanism of action.
