For anyone who may not know, a big thing for SeaWorld is its association with Killer Whales or Orca to give them their Sunday name.
So much so, their logo even incorporates this magnificent creature, as you can see.
SeaWorld has a general sea-related theme running through the park and the majority of the various shows and attractions, including sea-lions, dolphins and sea-otters, culminating in the main attraction; the Shamu Show. So called because of Shamu, the Killer Whale.
Shamu is of course a generic name, a brand if you like, as it can be any one of a number of Orca from the SeaWorld ‘cast’ that take the role in the show itself. Over the years, various Shamu have perished and been replaced with yet more. The show must go on.
