Sand Bat

A bat that hides itself in sand storms. They appear when the winds are strong enough to cause sand to rise into the air. These bats are quite a nuisance as they silently circle above their prey and nosedives to suck its target's blood, then escape instantly into the billowing sand. They aren't very reproductive, but they do live very long, so it isn't unusual to see waves of sand bats appear where winds are constantly blowing.
