do you know how heat makes life possible for the coral reef ?

corals have a fairly narrow band of temperatures in which they are happy.  If it is too cold they can't survive.  So they tend to not live too far north or too far south of the equator.  I imagine that they would not like it to be too hot either - but isn't that true of everything?
