Sand Spider

A couple of years ago, I saw a rare spider that looks like a sand.
When I saw it, It was resting on a mould sand as it was looking out for insect to prey on. I call it sand spider.

It's camouflage with the sand wouldn't let you notice its presence until you look closely. I think I was lucky to come across this rare special of insect and spider. This of specie of spider needs utmost protection to avoid it going extinct.
