Seahorses are small, thin fish. Even though they're fish, seahorses aren't great swimmers. Instead, they often use their tails(尾巴)to hold onto something in the water.
There are over forty different kinds of seahorses. Many kinds of them are in dangerbecause of the actions of hum:uns. Sometimes people catch and sell them as pets. They are also sometimes caught by accident when boats are trying to catch other fish.
Seahorses are unusual because they are the fathers who carry the babies. Fathers can carryover 100 babies at a time. When babies are born, they are about the size of a grain of rice.
Last year, around 380 seahorses were set free into the wild. To begin the project, scientists collected three"pregnant(怀孕的)"father seahorses and brought them to the aquarium(水族 馆). After the babies were born, the scientists kept them at the aquarium for five months, looking after them. About a month before the young seahorses were set free, the scientists created eight underwater "hotels"to provide a safe place for them to develop. Putting the hotels into the sea early allowed the hotels to be covered with small sea life that can help provide food for the
seahorses.
This is the fifth time the scientists have set free seahorses into the area. Brett Fenton, a scientist of this project, said, "We have high expectations(期待)that we'll see the number of the animals grow. "
