Sea horse is a type of fish. Sea horses breathe with gills, just like fish. Measure of sea horses varies, ranging from 16 millimeters to 35 cm.
However, sea horses have differences with fish. The difference lies in how to swim. The other fish swim by moving the fins, while the sea horses swim by way of up and down. This up and down movement is arranged by a swimming bag containing the air on its body.
The eyes of the sea horse can move in all directions. In addition, the seahorse's eye can also see two objects simultaneously. Sea eggs will be stored on the seahorse by the sea horse. So, when hatching then the sea horses will be born from the male sea horses.
