Sea dragons are fish.
There are two kinds of sea dragons:
the leafy sea dragon; and
the weedy sea dragon
In the sea they look like a piece of floating seaweed.
Fully grown they are about as long as your ruler.
Their bodies are covered in hard bony plates. It's a bit like armour.
Their fins are so fine you can almost see through them.
They have very good eyesight and eat tiny shrimps and sea lice.
They don't have any teeth so when they see something to eat they suck it through their tiny little mouth.
They live among the seagrasses in the ocean.
If we destroy the environment and the sea grasses disappear, the sea dragons will die.
Like most fish, female sea dragons lay eggs, but it's the males who get pregnant.
The female lays lots of eggs into tiny cups on the male's tail. The female then goes away.
About five weeks later the eggs in the male's tail start to hatch.
They can see and swim just as well as he can. Dad doesn't look after his babies. They have to find their own food.
It takes the tiny babies about 2 years to grow to their full size.
