If Hyenas are actually sharks, I don't know, but sharkss have beaten some dogs and birds on intelligence tests.
Most sharks are ectothermic, but some (namely the Great White) can produce their own body heat. They do this by using the heat produced by burning energy from pumping their blood. As blood is pumped to the body, the blood moving back to the heart gives off its heat which is picked up by the cold blood. In this way, some sharks can be warmblooded, but most are ectothermic.
