Reef Fish Identification in the Sea of Cortez, Baja Mexico

 
Jacques Cousteau described the Sea of Cortéz in Baja Mexico as the “world’s aquarium” and the “Galapagos of North America.” The beach 1/2 a block from our villa is adjacent to a wonderful reef full of fish and flora. We can wade into shallow water, slip into a lagoon or dive off rock into ten feet or more of clear, blue water teeming with life.

We are the furthest thing from pros in identifying what are mostly reef fish below. We’ve done our best based on multiple sources, all of which can be found linked at the bottom. We’ve only identified what we’re somewhat assured of having seen – this represents a small percentage of the amazing amount of sea life present around the reefs.

Images are from a variety of personal sites, royalty-free sites, Flickr, etc and are linked where possible (tip: if you’re coming down to Baja Mexico to snorkel, bring a waterproof camera or a waterproof bag for your point-and-shoot). Feedback is most welcome – Contact Us. Hope you enjoy almost as much as we did!
