The Cytoarchitecture of the Tectal-Related Pallium of Squirrelfish, sp.

The squirrelfish, which live in visually complex coral reefs, have very large eyes and a special dual-system "day and night vision" retina. They also have atypical expansions of brain areas involved in processing visual information. The midbrain tectum sends information diencephalic relay to two enlarged dorsal telencephalic regions.
