"The perfect gift for those of us who want to learn about and admire peculiar creatures like the Hogchoker sole and the Tadpole madtom in brilliant color photographs in the privacy of our home rather than by swimming about in dark watery caves highly hostile to human visitation. It would be a good present for real cave divers, too, or even top swimmers who want to know where the good springs are and what's in them." --Tallahasse Democrat
