Some elephants can talk
Kosik the Elephant made headlines in September 2006 when it was discovered he could imitate the Korean words for “yes” (네), “no” (아니오), “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 his or her mouth.
