The box jellyfish, aside from being the world's deadliest animal, is quite fascinating. So is the blue whale. Maybe you could call your paper Aquatic Intelligence. The dolphin is the most intelligent animal in the water with the possible exception of the octopus. A good title might be Here Be Healing because dolphins heal quickly and easily even from major injuries. They almost never bleed to death.

I need to write an essay at school about something that interests me - i initially thought i wanted to do a dolphin or marine biology related topic but i can't think of a question. Any suggestions?
