1In a world-record effort to help save a rare sea creature, Australian scientists have released hundreds of baby seahorses into the wild.The tiny seahorses are endangered,and the scientists hope the new seahorses will help their numbers grow.

2Seahorses are small,thin fish with a long snout (長鼻子).They're called“seahorses”because they look a bit like horses.There are over 40 different kinds of seahorses.They mostly live in warm,shallow waters around the world.They are often found in coral reefs, in beds of seagrass, and in areas where rivers empty into the sea.Seahorses form an important part of the ocean's food chain.They eat tiny sea creatures and are eaten by bigger sea animals,such as crabs.In a way,they play an important role in keeping the diversity of marine species.

3Many kinds of seahorses are threatened, often by the actions of humans.Sometimes they're caught and sold as pets.They are also sometimes caught by accident when boats are trying to catch other fish.

4Seahorses are unusual because it's the males who carry the babies.Males have a special pouch that allows them to carry over 100 babies at a time.The tiny babies are born alive and can swim right away.When they're born, the babies are about the size of a grain of rice.

5To begin the project, the scientists collected three pregnant male seahorses.Those seahorses were brought back to the aquarium.After the babies were born, the scientists kept them at the aquarium for five months, feeding the baby seahorses to help them grow strong.

6About a month before the young seahorses were released, the scientists created eight underwater“hotels”for them.The hotels look a little like cages, and provide a safe place for the seahorses to develop.Putting the hotels into the sea early allowed the cages to be covered with small sea life that can help provide food for the seahorses.The researchers also put tiny tags under the skin of many of the seahorses to help track them in the future.
