Hippocampus is not good at swimming, so it often uses a tail suitable for grasping to closely outline the branches of coral and the leaves of seaweed to fix the body so as not to be washed away by the rapids.
At rest, the hippocampus uses the curling ability of its tail to wrap it around the stems and branches of seaweed. Therefore, most seahorses inhabit deep-sea algae.

Living habits:
(1) activity
Because of its mimicry adaptability, hippocampus has a special habit, and it likes to live in the subtidal waters where algae or seaweed breed. Sex is lazy, often winding its curly tail around the stems and branches of seaweed, and sometimes hanging upside down on floating seaweed or other objects, drifting with the tide.
(2) Predation
In fish, the hippocampus has a unique curved neck, which looks like a horse with a long nose and mouth. The overall shape of seahorses, coupled with the absence of caudal fins, makes them the slowest swimming animals on earth. They can't swim fast, usually like seaweed, tied to the bottom of the sea with curly tails.
Hippocampus must use its bow-shaped neck as a spring and twist its head forward to catch prey, which also limits its effective distance to catch food, which is only equivalent to the length of its neck, that is, 0. 1 cm. However, the hippocampus can use the special shape of the head to quietly approach the prey and then capture it. The probability of success is over 90%. The mouth of hippocampus is located at the end of long nose and mouth. When moving towards the prey, the waterline near the nose and mouth hardly moves, so it can sneak up on each other and successfully hunt.
