A singigng animal

This is for my student challenge 7 activity 5, it said that I have to look reserch up any animals that migrate in my area.  Well I made reserches and found the animal that migrates and sings.  Its the HumpBackWhale! They stay in the tropical waters to mate in winter.  When theres summer they go to the cold polar waters and feed.  HumpBackWhales take a while to migrate, they can swim 3-9 miles per hour.  The humpbackwhales are also big animals they grow about 52 feet long and they weight around 30-50 tons.  Well thats all im going to say. Bye (:
