A juvenile Peacock Razorfish

Subject: A juvenile Peacock Razorfish (Iniistius pavo) is repeatedly diving into the sand. These youngsters mimic seaweeds or leaves to avoid predation. In addition to being excellently camouflaged they are very prudent as well: at the first sign of danger they hide underneath the sand, where they also sleep at night.

Technique: Because they are known to spend hours under the sand, it was sheer luck to find a specimen that performed a little “dive-in-the-sand” show. Most times they duck away to arise only when the potential threat (= the observing diver) has vanished.
