I also found writing my report very difficult. Something unusual is that Killer Whales are the biggest dolphin and an enemy to dolphins. What's sad is that some dolphins eat penguins. Bottlenosed dolphins once lived on land and have four legs. Baby dolphins and and adults live to 25 to 35 years old.
Bottlenosed dolphins whack fish with their tails to send it soaring in the air.
Then when the fish lands it is so amazed that it is easy to catch. That is information I got from an email. The person send's the email is a man named Jake the Sea Dog. The answer is the Commerson's dolphin. Jake the Sea Dog gave me a lot of information.
