Camouflaged critters include some of the most interesting in the ocean, but spotting them can feel like a game of Where’s Waldo. To give you an edge, here are five tips for finding these elusive creatures.

1 SLOW DOWN

The slower you swim, the better chance you’ll have of spotting those camouflaged creatures waiting for you to pass by.

2 GET LOW

Swimming close to the bottom and scanning the top of the reef line is a good way to spot sneaky fellows, such as octopuses, as they attempt to slink away unnoticed.

3 LEARN THEIR HABITS

Many hard-to-find critters have adapted to blend in with certain backgrounds, such as pygmy seahorses that only live on like-colored gorgonians. Learn where they hang out, and focus your attention there.

4 LOOK FOR THE EYES

Even when their bodies blend with the background, their eyes will give them away. A stingray can bury its body in the sand, but if you see two dark eyes jutting from the seafloor, you’ll know what’s underneath.

5 ASK A LOCAL

Local divemasters often know the locations of resident critters. Mention what you hope to see, and chances are, the divemaster can take you right to it.
