Reply to comment by isisis in Diving with a shark by chemistrynerd1994

I’ve always read that the nerves on the underside of their head trigger a bite reflex while on top they do not. Which is why they always touch them on top of the nose and never give them chin scritches in these videos.

I’ve had a nurse shark sitting on my lap and I’ve fed it from above. Rule number one, never ever put your hand underneath the nose of the shark or it’s bitten. The second good drops below the snout it’s gone in a flash. Now that’s Nurse sharks who are very docile, I am going to assume this is relatively common in how they’ve evolved those senses.

I've never heard of chin receptors. That's interesting!
