California orcas can flip over young great white sharks,inducing TI for so long the immobilized sharks,who must move to respire, essentially suffocate.Humans can also flip sharks into TI.By stroking a shark’s electrically-sensitive snout and gently turning it over,researchers can induce TI that lasts up to 15 minutes.That’s enough time to insert tags,remove hooks,and even perform surgeries.There are risks however:TI can hamper respiration and induce hyperglycemia, a sign of stress.So this technique should only be used when necessary.
