While we've all heard that fish can be brain food, Ichthyo: The Architecture of Fish serves it up as eye candy.

This beautiful book of black and white fish X-rays catalogs the eerie, intricate, and unexpected beauty of ichthyological specimens from the National Museum of Natural History's unrivaled collection, with an introduction by deep sea explorer Jean-Michel Cousteau (who takes after his dad Jacques). You'll never look at dead fish the same way again.

Thanks Lucy!
