MARINE BITES AND STINGS:

One of the most inviting, relaxing, and beautiful places on earth is the ocean. The soft, warm, luxurious sand, the gentle, soothing waves, and the spectacular bluegreen waters that reflect the colors of the sky, draw us near. As we relax in the warm, tropical water, we can’t help but wonder why anyone would have ever wanted to crawl out of the sea, so that they could walk on the hard earth, propelled by two small feet.
