I once experienced an unforgettable trip to Gloucester to see some of the world’s most beautiful and exciting animals in their own habitat(栖息地), the North Atlantic Ocean.
After a long trip by bus, we got on the ship. After a while, we stopped and everyone began to shout because we saw a humpback whale（座头鲸）. It was wonderful. Sometimes, whales came so close to the ship that you thought you could easily touch them.
While we were watching the whales, a guide was giving us some information about them, She told us that we saw only two kinds of whales- 50 foot humpback whales (singing whales) and 70-foot finback whales(the second largest whales on earth). She also said we could easily recognize a whale by its tail because every whale has a different kind of tail just like people have different fingerprints.
They all have names,and on this trip we saw “Salt” and “Pepper”, two whales named by a biologist and a fisherman. They were swimming toghter all the time.
I took twenty-seven photos,but it was very hard to take them because the whales were quick and stayed on the surface of the ocean just for a short time. It was really something. It was one of the chances that a person hardly ever experiences in life, but I had that chance.
