How did the sea horse get its name? It’s not hard to guess. The top half of this fish looks like a small horse. But looking at the sea horse’s tail, you might think “sea monkey” is a better mame. Then there’s the sea horse’s pouch. “Sea kangaroo” might also be a good name for this fish.
Sea horses live in warm ocean waters all over the world. They keep safe from other fish by hiding in plants and grasses that grow under the sea. They can also change colors to match their surroundings. A sea horse remains in one place for hours at a time by winding its tail around a plant. It feeds on live food, such as small shrimp. For a fish that doesn’t move around much, the sea horse eats a lot --- in just one day, a sea horse can eat 3000 shrimp!
A sea horse keeps the same mate for its whole life, and it’s the male sea horse that gives birth to baby sea horse. How does this happen? Baby sea horses start out as eggs, which come from the female’s body. The male carries the eggs in its pouch for about three weeks until they hatch. Soon after the babies are born, the female gives her mate a new set of eggs.
Sadly, 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 sold as aquarium fish. This really is not a good idea because most sea horses don’t live long in aquariums. The best place for a sea horse is the ocean.

The transition from old fuels to new will be slow, as will the development of new technologies that present feasible alternatives to fossil fuels or help eliminate food and water problems. All current technologies are inadequate, and new ones will probably not be commercially possible by 2025
