See The Fish? The Fish For Sure Sees You!

 Here’s something you may want to consider the next time you pound on the glass and make faces at the fish in the tank at the doctor’s office.  Researchers have discovered that those fish could pick you out of a lineup if need be.  So don’t do anything too crazy!

 LiveScience.com says for the first time fish researchers successfully trained tropical archerfish to select the "correct" image of a human face on a computer screen above their aquarium.  How did the fish respond?  How else, they demonstrated recognition of the face by spitting water at it.

They described the fish-face-training process as being “very similar” to training a dog. Every time the fish spit at things, they reinforced their natural behavior by feeding them when they recognized the face.

Recognizing human faces for a non-human creature is too difficult for many animals. It's something only a few animals have been able to do so --including horses, cows, dogs and some birds.  All of those animals have a neo-cortex structure in their brains, where facial processing and recognition takes place.  The fish are the first animals without a neocortex structure to be shown to have this ability.

This may be great if you are trying to find Nemo, but for the rest of mankind?
