It's not very often that a fish is both super colorful and super stealthy at the same time.
Some animals, insects, and fish all over this planet have a very unique ability to make themselves almost invisible when they so desire. This super stealthy technique takes place for a couple of reasons. Mainly, it's to hide from predators. Other times, it's to stalk food. In the case of the the two-stick stingfish, it does a little bit of both. As you are about to see, it is one impressive fish.
From the description in the video posted by the National Geographic, these fish are primarily only active at night. When this video was taken between the Gulf of Aqaba, between Egypt and Saudi Arabia, it caught everyone by surprise.
For the diver to see actually actually see this fish in the daylight through it's super camouflage, and catch it on video, well that's a pretty rare thing.
