Which fish is having 3 hearts?
The giant Pacific octopus has three hearts, nine brains and blue blood, making reality stranger than fiction. A central brain controls the nervous system. In addition, there is a small brain in each of their eight arms — a cluster of nerve cells that biologists say controls movement.

The danger comes when salmon return from the ocean to rivers to spawn. Trapped in rivers, as many as 40-90 percent of salmon may be killed not through fishing, but by driving.
