Blind Cave Fish in Limestone
Why do the Blind Cave Fish have to live in limestone
caves? What makes the limestones better than other rock?
Caves form in limestone rocks because of the physical and chemical nature of the rock; streams
and pools sometimes form from the water that helps create the caves. Therefore cave fish and
other animals live in limestone caves. "Caves" in sandstone are generally only shallow shelters
without water, small caves formed in lava flows are also almost always dry.
