Even though the sea horse is a fish, there is very little about it to suggest a fish. It has a head shaped like a pony. Instead of scales, the body of a sea horse is encased in rigid plates and thorny spikes. And its tail is like a snake’s!

The sea horse doesn’t even behave like other fish. It usually curls its tail around a bit of seaweed in the water so that it won’t be swept away by the current. When it does swim, it moves about with the help of a single fin which is located on its back, and it moves upright through the water.
