he arrived, i think in 1992. i was at whale and dolphin stadium when he arrived. he's twice as large as the next animal in the facility. >> right at about 12,000 pounds. that's -- that's incredible. he looks fantastic. >> when tilikum arrived at sea world he was attacked viciously repeatedly by katina and others. in the wild it's a very mate society. males whales are kept in the perimeter. in captivity, animals are squeezed into very close proximity. tilikum, the poor guy is so large he couldn't get away because he just is not as mobile, relative to the smaller and more agile females. >> he spent time in isolation. seaworld claims he's always with the females but from what i saw he was mostly put with the females for breeding purposes and he didn't spend a lot of time with the other whales.
