The Cyprinodon diabolis or Devil’s Hole Pupfish is the world’s rarest fish. It’s so rare that you will only find them in Nevada’s Death Valley National Park in a tiny limestone cavern called the Devil’s Hole.
You will find this majestic fish in the Northern Pacific off of California and Baja California. And, as we’ve mentioned earlier, this fish is huge. As a matter of fact, the largest Giant Sea Bass ever caught measures 7.4 feet long and over 560 pounds!
You can identify the Peppermint Angelfish by its vibrant colors – bright white stripes paired with a neon orange body color. But despite its attention-grabbing color, you will only find this elusive fish in the central, eastern, and south Pacific oceans, where they occupy reefs and cliff shelves.
Their population has experienced a steep decline, as much as 80 percent. The only resolution to this species’ survival is captive breeding and then releasing them back into their natural range.
