Thank you Curt, the science is constantly discovering new things, sometimes it is hard to keep up...
Changes are part of life
For example, look at one rock at Keystone:
Story of one rock. One of many creating the Keystone Jetty. Fourteen years ago, there was Giant Pacific Octopus making it its home. It was probably there even before that, but on October 23,2003 I tried to take a picture of it with my Nikonos camera. How much changed since then. The Sunflower stars got almost wiped out by the Wasting Disease, the octopus gone its den filled with debris and sand, the purple encrusting coralline gone, the rock now covered by carpet of barnacles. The one critter which endured all those years - yellow colored Painted anemone. Its scientific name changed from Urticina crassicornis to Urticina grebelnyi, but so far, it moves very little and from what I can tell, it is happy there, not growing bigger, one constant in our changing world.
