I've heard bad things about this fish, but I've had it raw as sushi a few times and nothing bad has happened.

Small amounts of escolar is fine for most people, so if you're eating it in sushi rolls along with other types of fish you're unlikely to eat enough of it to run into trouble.

I think the proper butterfish is something else entirely.

Escolar filets looks like big tuna filets.
