Wild animals are 100% preservation first. The elephants, seals and sea lions that you see being nice to people have been trained that people are not a threat.
During a show at the Mirage on Horn's birthday on October 3, 2003, a seven-year-old white tiger named Mantacore attacked Horn. (The name of the tiger has frequently been misspelled as "Montecore" in media reports.[16]) As part of the act, but veering off script, Horn held the microphone to Mantacore's mouth and told him to say "hello" to the audience. Mantacore responded by biting Horn's sleeve. Horn swatted the tiger and barked "release!", while standby trainers unsuccessfully attempted to distract the cat with cubes of meat. Possibly incited by Horn's retreat, the tiger leapt at Horn, swinging at his legs and knocking him off his feet.[16]
As trainers rushed to the stage to assist, Mantacore bit into Horn's neck and dragged him offstage toward his cage. Trainers finally got the tiger to release Horn by spraying him with CO2 fire extinguisher canisters, which was the last resort available.[16]
I think people assume they're friendly because they can be pretty curious, which can appear like friendliness, but I've heard they're aggressive biters when messed with.
They have a high bar as well. You could do so much as try to get too comfortable near their flock and they'll attack you. All three animals have a known altruistic side, but this is balanced by a heightened degree of erraticness.
That's stupid. A blooded Yautja can easily jump over 18' vertically and some clans can jump over 40' vertically, no chance those little barriers are going to stop one from getting at their quarry.
Only when they've been stuffed or turned into a coat or rug (or ivory carvings in the case of walruses, specifically the tusks) they're assholes otherwise.
I remember reading a story related by a nature photographer who was swimming with leopard seals. Apparently one of them liked him, and thought he might be hungry, so it casually ripped the head off a penguin and offered him the corpse.
