Photo Jewelry Dolphin Collectible gifts - Pendant /Necklace

• Most researchers agree that dolphins exhibit a level of intelligence greater than that of dogs and even comparable to that of some primates, but not human beings. They adapt well to human companionship and are readily trained. Bottle-nose dolphins have become well known performers in many aquariums; they are capable of spectacular tricks and may mimic the sounds of a few human words.

• Dolphins sleep with only one half of their brain at a time. Because they are conscious breathers, if they slept like humans they would suffocate or drown. Sleeping dolphins can be seen as resting, floating at the surface, with one eye open. After a time, they will close the one eye and switch to the other one. They alternate like this throughout their entire nap.
