I only realised they could swim a few weeks ago after reading a news article.A man was walking his dog on a beach in Australia when he saw a Kangaroo in the sea. A few moments later a shark pounced on it and dragged it down. He reported it to the police who did not believe him at first then someone else reported it. Remains were also found washed up on the beach.They said it was very rare as Kangaroos don't normally take to water.The original meaning of the word "Kangaroo"."I don't understand"
