Though still a juvenile, the great white shark at Monterey Bay Aquarium exudes the presence of an apex predator. Nothing in the tank was running away from it, but they weren't coming near it either. Right now it's only 5 feet 8 inches, but I still would not want to fall into that tank...
i often wonder if these great white attack people even when they are not hungry??
don't think so. Only Tigers do that. Keep Great Whites fed and they are relatively docile.
