About This Quiz
Thinking that dolphins and sharks are related in some way is the sort of mistake that can be forgiven, but thinking they are the same is dangerous. Dolphins are highly intelligent marine mammals. They are about as smart as very young human children. They give birth to live young. They have to breathe air, forcing them to return to the surface every now and then for a quick gulp of oxygen. Likewise, whales are mammals, but due to their much more massive lung capacity, whales can spend much longer underwater. Some whales can stay underwater for as long as 2 hours, allowing them to dive deeply and feed on creatures we never get to see.
Sharks are another matter all together. Sharks are a kind of fish, not mammals. Sharks breathe through gills that require them to either move or remain still while a current moves oxygenated water through them. Sharks come in more varieties than dolphins and whales, from the lumbering, harmless, and strangely named whale shark, to the exceptionally dangerous and aggressive tiger shark. Sharks and dolphins may both have dorsal fins, but aside from that they couldn't be more different. Take our Myers-Briggs Personality Test and we'll tell you if you're a shark, a dolphin or a whale!
