Ever wonder how a school of fish moves like it's one animal? No leader, no rehearsal โ they just feel it. A sensory organ called the lateral line lets them sense water movement from every fish around them, so they can turn, dart, and swim in perfect sync without ever touching.
It's also a defense mechanism that makes it harder for a predator to zero in on one fish when there's a hundred of them moving as a blur. ๐
