As we know,all animals would have their children.Most of them must protect their children until they are old 1 to take care of themselves.A fish that swims in the rivers of South America 2 its young in a 3
way.This kind of fish uses its mouth to keep its babies 4 danger.
When it lays the eggs,it 5 them in the mouth.Of course we know,it does not 6 during the time.After the eggs hatch,the fish swims 7 its babies to protect them.It 8 its mouth when 9 comes near and the young fish would swim inside.They swim out only when it is 10 again.
The way to protect the young works well.I think.
