2. Better known as the Black Ghost Knife-
fish.
It is native to South America in the Amazon
basin.
They like to live in fast moving sandy
water in tropic like climates.
They can be found in the Paraná River but
mainly in the Amazon River
South American natives believe that the
ghosts of the dead are resurrected in

3. Recent discovery shows like than of an
electric eel the knife fish has an
electrical field.
Unlike a eel it does not use it to Paralyze
its prey.
It uses its electrical sense to
communicate, navigate, and hunt.
Since they are a nocturnal fish there
electric field tells them what's around so
they don’t get killed
There electric field is produced by a
small organ in its tail and small
receptors along the body
4. Knife-Fish are a weakly electric fish but
needs the electric field to do simple daily
tasks.
It allows the fish to know what is happening
360 degrees around its’ self so it can escape a
threat.
as well as protecting its’ self it also lets the
fish know if it has prey near by.
It also uses this sense to communicate with
other knife-fish.
And being a nocturnal fish it also uses this
sense to navigate around in the dark murky
water.
5. The fish is all black except
for two white rings on its
tail, and a white blaze on its
nose, and rarely extend into
a stripe down its back. It
moves mainly by a long fin on
its stomach. It does not have
scales.
