The dolphin is called a "smiling angel", and "is it expressing happiness?"
Yes, of course
Not really
Correct Answer: Not really
Answer Analysis:
Dolphins are often referred to as "smiling angels" because they always seem to be smiling. But in reality, this "smile" is not an expression of happiness by the dolphin, but by its unique facial anatomy.
The dolphin's mouth is naturally upturned at both ends, creating a smile-like arc. This shape helps dolphins reduce water resistance when swimming at high speeds, improving swimming efficiency. At the same time, this upturned mouth also makes the dolphins look very friendly, giving the impression that they are smiling all the time.
Although dolphins' "smiles" are not expressions of happiness, that doesn't mean they don't have emotions. In fact, dolphins are highly intelligent and emotionally rich animals. They have complex social lives, forming close group relationships and communicating through a variety of voices and body language. Dolphins also exhibit compassion, mutual support behavior, and a love of play, all of which indicate that they have a rich emotional world.
In addition, dolphins' interaction with humans also shows their positive, friendly side. In many marine parks and interactive programs, dolphins often actively interact with human visitors, showing curiosity and closeness. While these behaviors are not exactly equivalent to human smiles, they reflect the positive, outgoing personality traits of dolphins to some extent.
In conclusion, although the "smile" on the face of dolphins is not an expression of emotion, they are indeed highly intelligent and emotionally rich animals. Understanding dolphins' behavior and communication patterns helps us better understand and appreciate the unique charm of these "smiling angels".
