School’s out… but schooling is still in session!
These fish aren’t performing a practiced routine. They have a specialized cells used for sensing the underwater world called the lateral line(check the comments for a picture)! This system helps them detect movement and pressure changes in the water, allowing them to stay together and move in sync while schooling. Swimming in large groups helps protect them from predators by making it harder for one fish to be singled out and increasing the group’s awareness of danger!
