Using language for listen to the conversation again and answer the questions . here at the cat. We are wild about whales today. You have been helping us without whale research. First of all, we ask you to find out some facts for a while. E profile, what did you find? Sally? There are over eighty different species of whales. These include the blue whale, the largest known animal to have ever existed. They can grow to one hundred feet long and can way nearly two hundred times. There are two main types of, well, those with teeth and those without, those without teeth eat very small organisms, whereas those with tea eat fish and other larger sea animals.

They can learn by themselves and can teach the things they have learned to their Young. We want to understand more about . this very good bin. And lastly, we asked you to go out with us on write report of the work we do. Can you give us your report? look? yes. First we followed a group of whales with the boat. Then we took pictures of their fans. Most whales have slightly different fans and Marks, which can help to tell them apart. Meanwhile, we also noted their location so we can track their movements and plot their migration path. Later, we created a database of their friends and locations. After that, we gave the group of whales and name and each member a number. They will be added to the directory so we can identify them in the future. Finally, we contacted other the whale research groups around the world to share the information with them. excEllent. Thank you all for your help today.
