What is the name of the trance-like state of temporary paralysis that sharks enter when flipped upside down?
Tap your pick
Tonic immobility is a natural, involuntary reflex in sharks that can last up to 15 minutes. Scientists often use this safe, non-chemical method to calm sharks during research and tagging procedures. Interestingly, some killer whales have learned to exploit this vulnerability, holding sharks upside down to suffocate them. Photo: PARAKANYAA, Wikimedia Commons, CC BY 4.0.
