Dolphins VS sharks, hmmm. Sharks are pretty strong but dolphins are better. Sharks have pretty sharp teeths but dolphins are much more smarter faster and can kill sharks by smashing their strong beaks right into the sharks gills. Sharks can swim ten to twenty miles per hour but dolphins can swim up to thirty miles per hour, let's go for the dolphins. Sharks has sharp teeths but dolphins has a really strong beak that can kill sharks. The dolphins is now the winner.
