Dolphins ‘deliberately get high’ on puffer fish nerve toxins by carefully chewing and passing them around

Dolphins are thought of as one of the most intelligent species in the animal kingdom – and experts believe they have put their ingenuity to use in the pursuit of getting “high”.

In extraordinary scenes filmed for a new documentary, young dolphins were seen carefully manipulating a certain kind of puffer fish which, if provoked, releases a nerve toxin.

Though large doses of the toxin can be deadly, in small amounts it is known to produce a narcotic effect, and the dolphins appeared to have worked out how to make the fish release just the right amount.
