Kosik is a male Indian elephant in the Everland theme park in Yongin, South Korea. He made headlines in September 2006 when it was discovered he could imitate the Korean words for "yes" (네), "no" (아니요), "sit" (앉아), "lie down" (누워), and four other words. He makes the sounds by putting his trunk in his mouth and shaking it while exhaling, similar to the way a human whistles with fingers in their mouth. Kwon Su-wan, director of the zoo in Seoul, said: "We plan to conduct further studies with keepers, veterinarians and scientists on whether Kosik understands the meaning of these words as he speaks them."
