The meaning of shark fin tattoo is to maintain stability and power. When a shark swims, it leaks a dorsal fin on the water. This is a scene in many animations. Then we are also impressed by this picture. In fact, under normal circumstances, the shark does not leak its dorsal fin out of the water.
Shark fins can help sharks maintain balance, which is equivalent to the orientation tool of sharks. Sharks without shark fins can not even maintain balance in the water. As for why sharks leak their dorsal fins on the water surface, this is also a helpless move. Because of the water depth, sharks have to leak out of the water. Usually when the shark leaks its fins out of the water, it is ready to attack.
