Tonic immobility: sharks can be put into a “coma” for up to 15 minutes by stroking the flesh around their snout. This technique is thought to overwhelm the shark’s electro-magnetic senses (the ampullae of Lorenzini), and is often used in shark rearing and husbandry. Orcas have also been observed putting sharks and rays in a state of tonic immobility, which makes them an easy meal.For teaching: marine science -- source link
