Let’s talk stingrays for a minute.
Stingrays are found quite frequently while diving here on Koh Tao. There are two main types of stingrays that we see: The blue spotted ray and the Jenkin’s whipray.
The blue spotted ray is the more common stingray and its usually found subtly hiding under rocks during the day, although occasionally they’ll be just chilling out in the open almost as if they want divers to check them out. They have very alien-looking eyes that protrude from their heads and spiracles behind their eyes to allow them to breathe. The blue spots serve as a warning to other fish that they are poisonous and should not be messed with. But no need to worry, they are not aggressive in the slightest and are perfectly safe.
The Jenkin’s whipray is rarer and although it doesn’t have any bright colors on it, it is a little more spectacular due to its larger size. It’s quite a sight to behold.
Both rays are more active at night when they can be seen swimming around and hunting for mollusks by digging into the sand. It’s one big attraction of doing the night adventure dive on your PADI Advanced Open Water course.
