That estimated 50-80% of all life on earth is found under the ocean surface and the oceans contain 99% of living space on the planet. Less than 10% of that space has been explored by humans. Scuba Diving opens up this world full of creatures, fish and marine life.
Marine life is indeed very intriguing and may look like alien beings to us. Many marine creatures are ancient and have been on this earth for millions of years. Let us catch a glimpse one of the fascinating marine creatures, the string-ray, which are mesmerizing and can be dangerous.
From my first dive I get fascinated with Stingrays as they gently glide a few inches above the sand, stingrays appear elegant, peaceful and clam.
Stingrays are some of the most unusual animals in the ocean. They spend the majority of their time inactive, partially buried in sand, often moving only with the sway of the tide. The stingray’s coloration commonly reflects the seafloor’s shading, camouflaging it from predatory sharks and larger rays. We can found stingrays in shallow coastal waters of the temperate, tropical and subtropical regions as well as in coral reefs. Stingrays have a flattened body and a tail region where the stingers are found. Just like sharks, they have electro-receptors known as the ampullae of Lorenzini with which they detect prey. They eat mollusks and crustaceans like clams, oysters, etc, and sometimes small fish. They normally do not attack humans but will do so in self-defence. Death of human beings from the stinging of stingrays is very rare. Unfortunately, the famous wildlife enthusiast Steve Irwin died from a fatal sting of a stingray.
