The whales and dolphins are starved before each show and not fed until after they perform all of the tricks. The killer whales have sunburns all over their bodies from living in a hot, sunny, shallow pool their entire life in the sun drenched cities that all the SeaWorld parks are located in. (SeaWorld's locations are in sun drenched San Diego, CA, San Antonio, TX and Orlando, FL.) Yet in the wild they swim at much lower depths and are able to avoid the sun. The trainers paint over the killer whales' sunburns with black zinc oxide in an attempt to hide their sunburns from the public. Thus opening a SeaWorld park in Dubai would be incredibly cruel because the Orcas will be forced to endure the hot Dubai desert sun beating down on them and they won't be able to escape it since they will be trapped in a shallow swimming pool.
The whales have dents and gauges all over their bodies from ramming their bodies into the sides of the tanks in their attempts to escape. The whales' teeth are grinded down from biting the edges of their glass enclosures while trying to escape. Worst of all, the SeaWorld trainers rape the whales. The trainers masturbate the male whales, then put his sperm in a pump and shove it inside the female whales' genitals. That's right, the SeaWorld trainers rape the whales in order to force them to get pregnant so they can breed more captives.
