Movement

The structure and function of the seahorse's tail is very different from that of other fish. When perched, seahorses utilize the tail's ability to curl, allowing the tail end to wrap around seaweed stems and branches. Therefore, seahorses tend to live in the deep sea where the algae are thick. Swimming posture is also very special, head upward, the body slightly oblique upright in the water, relying entirely on the dorsal and pectoral fins to carry out the movement, fan-shaped dorsal fins play a role in fluctuating propulsion.
