My son is an avid scuba diver who dives in underwater caves. He recently took a scuba cave diving trip to Twin Springs, FL. The following are the photos he took there. I don't know the details about any of these photos, so I put them up on my web site without any comments. If you're a scuba diver, you might, nonetheless, find these photos interesting. Others from this trip will be added here later

You'll see many of these photos are of crawfish. It might seem less strange with this explanation: The only fauna who survive in this underwater cave are blind crayfish. These creatures have been living in these caves for millions of years, and have evolved without any eyes.
