Boxfish are often compared to helicopters. Their box-like shape reminds of some helicopters, the "rotation" of the pectoral fins remind of helicopters. And like helicopters, the heavily armored boxfish can hover, move slowly, at medium speed, or fast. How they do that, you can see in this OceanQuicky.
