Dozens of dolphins were leaping on the sea surface, occasionally changing formations. Sometimes they formed a circle, sometimes a fan shape, just like dancing in the water.
"What are they doing?" Chi Enen turned her head and asked.
"There's a school of fish underwater."
Chi Enen looked closely and indeed saw the school of fish being surrounded in the middle.
"Dolphins use ultrasound to influence the swimming direction of fish schools; they are hunting."
Chi Enen said in disbelief, "Did you know they would gather here?"
"Are you silly? How could I possibly know this!" Li Beijue swept her with a glance of his pitch-black falcon-like eyes, his thin lips touching, "We were just lucky to bump into them."
Generally speaking, it's impossible to see dolphins unless you're in the deep sea, let alone watching them hunt in groups.
Their ability to see it was likely because the fish school happened to come here, and the dolphins followed along.
