Lined seahorse (Hippocampus erectus).
Snipefishes move through the water using their caudal, or tail, fin for propulsion. They are notable for swimming in a head-down position and are capable of moving forward or backward with equal ease on the vertical plane. Unlike many other members of the order Gasterosteiformes, snipefishes do not seek shelter among marine growths, such as corals or plants.12
