What kinds of fish can swim backwards?

Ostraciiform locomotion is the movement of fish where only the caudal fin oscillates from side to side in a manner similar to moving a boat with one oar. Boxfish, cowfish, and trunkfish all swim in this manner, mainly to avoid predators, and they are surprisingly good backward swimmers despite it.

Do dolphins have two brains?

Dolphins have large brains with two hemispheres that are able to sleep at different times. Studies using the electroencephalogram (EEG) have shown that large, slow brain waves of sleep may appear on one brain hemisphere, while low-level, fast activity characteristic of waking may appear on the other brain hemisphere.
