Fourteen-year-old Miguel Diaz talks about an exciting science project. Last month I got the chance to take part in an underwater research project in an area of the Gulf of Mexico called the Flower Gardens. A team of professional researchers, led by the scientist Dr. Matt Phillips, was trying to learn more about the fish and different kinds of creatures（生物）that live in this part of the sea. The Flower Gardens are a long way from the shore and we spent three days on a boat.
The team used a piece of underwater equipment called a Remotely Operated Vehicle (ROV) to collect information. The ROV could measure water depth and temperature and it also had a camera that sent live film back to operate it a few times.
However, the thing I enjoyed most was diving (潜水) into the water. At first, I was quite scared---mainly because I couldn’t' t see land in any direction. But as soon as I jumped into the water, I wasn't afraid anymore. It was amazing to see the colorful fish swimming around and I could see all the ways to the Flower Gardens, which arealmost 30 meters down.
I will never forget the Flower Gardens. The trip was like a holiday but I also learnt new things about science and research projects. It was a great opportunity and it has made me think about my goals (目标) in life. The experience will help me work harder to become a scientist.

How did the sea horse get its name? It’s not hard to guess.The top half of the fish looks like a small horse.
Sea horses live in warm ocean waters all over the world. There are 32 different kinds of sea horses. Their sizes are quite different from one inch long to about one foot long. Because their fins are small, sea horses swim very slowly. They keep safe from other fish by hiding in plants and grasses. They can also change colours to keep themselves safe. Sea horses feed on live food, such as tiny shrimps. A sea horse has no teeth, so it eats the shrimp whole.
A sea horse keeps the same mate for its whole life, unlike most kinds of fish. And it’s the male sea horse, not the female, which gives birth to baby sea horses. How does this happen? Baby sea horses start out as eggs, which come from the female’s body. But the female places the eggs in the male sea horse’s pouch (育儿袋). The male carries the eggs for about three weeks until they hatch (孵化).
The number of sea horses is becoming smaller. Why is this happening? Some places where sea horses once lived have been filled in to make new land. Also, many sea horses are caught and kept in aquariums (水箱) where they can’t live long. The best place for a sea horse is the ocean. There it can find a mate and bring new sea horses into the world.
