                     MORE ABOUT ADAPTATION, EVOLUTION AND CHANGE 

         Dolphins only eat fish  Their teeth are shaped just perfect for catching and eating fish.  Over the years, as the teeth wear down, the younger dolphins help feed the elderly ones in their family.

         Fish such as hard-headed catfish, stingrays, scorpion fish and puffer fish can harm dolphins.  How doe the young dolphins learn to leave these fish alone?  

        Their elders teach them not only which fish to avoid but how to catch the fish they can eat.  Each fish behaves differently, so the strategy to catching them is different.  All of this is taught to them by their elders who learned by trial and error many generations before and passed this knowledge down.

       Adaptation, change, and evolution, we see it all in the lives of the delightful, intelligent dolphins.
    Scarlet Colley of the Sea Life Center, Port Isabel, Texas writes these interesting articles.

         The area in and around Port Isabel is a wonderful place for taking a "SPICE" Adventure Walk and boat excursion.  Our latest book: "Pink Hat's Adventure with Seagulls, Hats, and Dancing Feet" includes such a walk around Padre Island.  See our website: HTTP://www.free-energy-env-exp4kids.com for more experiments and activities.

     The 'C' in SPICE stands for change and continuity.  The brown pelican of South Texas is a wonderful example of both change and continuity.  It is here that the western and eastern pelicans gather.  Come spring the eastern pelican's pouches turn green, while the western pelican's pouches turn red. And during this mating season their brown eyes turn 'blue'.  Sould a pair of pelicans, one from each group mate, their offspring turn half red and half geen on their pouches!  That is how you know that east met with the west. All of this is a great example of CHANGE meant to insure the survival of the species through reproduction.

         So where does Continuity come in?  Well, when mating season ends, and the egg sitting begins the pouches turn back to their original dull colors and the eyes turn brown again.  Now they are busy raising the next generation of brown pelicans.  This pattern is repeated year after year and that is CONTINUITY.

         By the way, brown pelicans are only brown for the first few years of their life.  After that they turn gray for the rest of their lives.  So why are they referred to as "brown" pelicans?  

         What do you think?
