“I’ve never met an alligator that will not bite you,” Henney told CBS Evening News in 2022, external. “You fool around the head like this (Joe puts his hand in Wally’s mouth), their instinct is to grab you [with their teeth] – but he does not do it.
“You can reach in and rub his tongue, he refuses to close his mouth, but we don’t know why,” added Henney.
Wally, who is about nine years old and 6ft (182cm) in length has an estimated bite of 3000 pounds per square inch.
