Scientists in the US and Canada have discovered the existence of short-distance flying fish on the sea.
This fish has a pair of large fins and a pair of small fins.When flying, they flap like a bird flapping its wings.
In addition to the four fins, the scientists also found fish flying in two fins.Previous studies have shown that in the past, four-fin fish had only two front fins, after which the two fins grew further in evolution.
"Flying fish" can surf a distance of up to 400 meters above the water.They can change direction and altitude while flying.The two fins fly much shorter and in a straight line.
The length of the fins and fins of the two fins is larger than that of the four fins.
Surfing on the water can be an effective tactic for fish to deal with water predators like seabirds, sharks, and dolphins.
A four-fined fish has patterns on the body.
