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.
