After teaming up with a group of shark experts, Mackie explores "the latest science that may help both human sharks co-exist in the great state of Louisiana", and RadioTimes.com has an exclusive first look!
In this teaser, the actor performs the delicate task of swabbing a shark's anus to test her faeces for dish DNA.
According to the experts, the sample will show if the shark has been eating the same prey that the fishermen are looking for.
In the clip, Mackie narrates: "Like many sharks, flipped on her back she enters a trance-like state and will be less stressed out, which is lucky, because now I have a pretty... let's say delicate job to do."
Mackie can then be seen swabbing the shark, and jokes: "When I woke up this morning, I didn't think I would be giving a shark an anal swab."
