Seahorses lack jaws to chew food. Instead, they get snouts with a powerful sucking mechanism. These narrow snouts create a strong jet of water to suck in food into the mouth cavity and during the process, disintegrating it.

In the video, you can see a mechanism similar to a trigger visible under the chin. This trigger will further produce a strong suction by accelerating the water movement through the seahorses’ siphons. The video shows four tank-raised seahorses, Hippocampus erectus, feeding on frozen mysid shrimps.
