Q:
A: hey man, if you are talking about the hook going into the fishes mouth then the answer i would have to give you is no. inside the mouth is very hard and rigid. the mouth holds no nerves. that enables the fish to eat pretty much what it wants. it protects them from fins on other fish while they are eating another fish and other hard objects that they might consume. if wondering if hurting the fish is stopping you from fishing, dont sweat it, no you are not going to hurt them. if you are planning on eating the fish and if you are wondering if they feel pain while you clean them....hell yea they feel that but there is something else that can help with that as well. just pack them with ice as soon as you catch them. they are cold blooded and their body temp will fall and they will pretty much go to sleep and they probably will not feel anything when you are cutting their heads off..me....i dont worry about it, streight out the live well and right to the cleaning table..to each is own...good luck and good fishin
