Today's interesting fact has to do with the Pike. This is a large carnivorous fish, called the Jackfish in some parts of North America and the Gar in others. It is found throughout the northern hemisphere.

Pike can grow to four feet in length, about 1.5 meters, and eat everything from fish, frogs, birds and other pike, ambushing their prey. Although it is considered a fresh water fish, it also can live in brackish waters, and has been seen eating herring on in salt waters.

In an attack it has been calculated that during its lunge for prey the Pike subjects itself to more than 10g of force, if only for a short distance.
