It’s amazing that the ocean has built a variety of life. It’s hard to count their types. But if you ask who is the smartest animal in the ocean, there must be a definite answer. It’s “killer whale”. Killer whale is a highly intelligent lactating animal with self-awareness and can interact with humans. It can be called a genius among marine animals.
When scientists study killer whales, they find that they not only have highly developed wisdom, but also have very rich emotions. When hunting fails, they will throw the pot to a culprit, and then have a critical fight to vent.
