There is an interesting fish that lives in the middle of our coasts, with an appearance that is hardly fish-like. The head is a bit like a horse, so it is called a seahorse; it is also a bit like the legendary dragon, also called the dragon drop.

The seahorse is generally about 0.1 meters long, the body is not scaly, the surface of the body is surrounded by bone plates, forming a hard armor, so that the body can not be bent. The torso is six-angled, the tail is four-angled, and the tail is long and thin, but the end is free to move.

The head of the seahorse is attached to the trunk, with a thin neck in the center, a long snouted cephalic tube protruding from the front of the head, and a protruding crown at the top of the head. There are two nostrils on each side of the head, a protruding thorax and abdomen, slit gill holes, and no ventral or caudal fins.

The eyes of the seahorse, can be turned up and down, left and right, or forward and back. Sometimes, one eye looks forward and the other backward, something no other animal but the dragon and chameleon can do.

The male seahorse has a brood pouch on its ventral surface, in which the eggs are laid for incubation, and can reproduce for two to three generations a year.
