By the spelling, I can tell that's just "orca" spelled in katakana (the Japanese alphabet used for foreign words) and then transcribed into romaji (Japanese words spelled using the Latin (Roman) alphabet). There isn't a character just for "r" or "l" in Japanese, so when spelling foreign language words, they often use "ru" for "r" or "l".

So essentially, they're using the word "orca" as well, but its spelled and pronounced slightly different because of minor translation barriers.
