Have you heard of the Elephantnose fish?

The more scientist learn about the brain the more they will be able to help humans impaired by Neurological Disorders.
With its tiny brain (and no cortex), the elephantnose fish (Gnathonemus petersii)* achieves performance comparable to that of humans or other mammals in certain tasks, according to zoologists at the University of Bonn and a colleague from Oxford.

To perceive objects in the water, the fish uses electrolocation (similar to the echolocation of bats) to perceive objects in the water, aided by an electrical organ in its tail, which emits electrical impulses, and numerous electrical sensor organs in its skin. It also uses its visual sense.

Curiously, in an experiment** in which the animals became familiar with an object in an aquarium with the visual sense, they were also able to recognize it again using the electrical sense, although they had never perceived it electrically before.
See link.

I've never seen nor heard of " elephantnose fish".
Interesting, and apparently smart little guys.
As I recall, it's not overall brain size that is common in intelligent critters, but brain size relative to body size.
In other words, a very smart animal might have a small brain compared to other animals, but a large brain for it's size.
