The Sandfish


Possibly the most amazing lizards now exist on Earth. A lizard of just 10 cm long (some specimens reaching 20 cm) and a truly curious peculiarity: anything under the sand.

The name given is "Sandfish", and that is, as we said, nothing in the sand, not water. The Scincus scincus (is scientific name) slides across the sand of the Sahara Desert, which is the finest sand in any other desert in the world.

It has a long snout wedge that opens the sand with a countersunk lower jaw. A long, tapered body covered with smooth, bright and tight scales that favor reduced friction with the sand particles.
Their legs are short and stout, with long and flat feet that hides when immersed in the dunes and its tail is short, tapering to a fine point. Their eyes and nostrils are very small.


But apart from his physical appearance that catches your attention is the ease with which it moves through the inside of the arena. Rather than for any other animal would be impossible or by working hard (in the case that could swim through the sand) and sand the fish as if they really get it traveling through water. Had hitherto been a mystery, but technological advances show us how this curious animal is able to swim in the sand:

Let us first see how it does.



Now let's see how he does it but X-ray


Amazing.
