Which animals with high IQ surprise you the most?

Black whale is a high IQ animal, which can be hunted with bait. The most interesting thing is that killer whales are talkative. The languages of different nationalities are similar and different, just like human dialects. When different groups meet, they will inform each other. If they don't speculate, they will quarrel and even be cynical. Scientists have analyzed ironic language similar to human language, such as "You are a big fool … you are so stupid …". When young killer whales are uncooperative, they are full of these words.
