The Intelligent

Different with the common perception that sharks are "eating machines". Recent studies showed that sharks are powerful in problem solving skills, social skills and full of curiosity. Sharks’ brain to body-mass percentage are the same or similar to mammals and birds. Unbelievable, sharks can take part in playful activities. For example, researcher figured out that Porbeagle sharks again and again rolling in kelp and chasing people who follow a piece of kelp behind it. In 1987, near Smitswinkle Bay, South Africa, there was a group of sharks worked together to move a dead whale to deeper water to be eaten. This can be a proof that sharks are good in solving problem and high in social activities.
