Unique Marine Life in the Florida Keys
The Florida Keys is like diving into an underwater jungle—except it’s full of things that swim. You’ve got reefs bursting with life, wrecks that have become homes for massive fish and open waters where surprises may be lurking. These keys don’t do boring.
Here’s a just a tiny example of what you’ll find scuba diving in the Florida Keys:
- Tropical Fish: Picture bright flashes of yellow and blue as angelfish dart past, schools of shimmering silver, colorful clownfish and much more. These little guys bring the reefs to life.
- Sea Turtles: There’s nothing quite like spotting an old sea turtle. They’re graceful, and they seem to have a calm, slow-motion vibe about themselves.
- Reef Sharks: If you’re lucky, you might see a reef shark cruising by..
- Goliath Groupers: One of the bigger fish you’re likely to see. They are usually huge and somehow still kind of chill as they hang around shipwrecks and on the reef.
- Spotted Eagle Rays: Not as common as the fish, but when you see one, it’s a thing of beauty. They glide through the water with elegance!
And that’s just scratching the surface. You might catch a moray eel peeking out of a crevice or find yourself surrounded by so much coral it looks like a postcard. No two dives are the same here, and honestly, that’s the magic.
