Species Hippocampus guttulatus (Long-snouted seahorse)

Grow up to 12-16 cm. Its body is laterally compressed. Dorsal and pectoral fins are fan-shaped and small, caudal fin has evolved into a tail that allows this species to fix on algae and plants. Long snout. Usually presents dermal filaments all over its body. It presents 46 to 52 rings along its body. Coulour its variable from dark brown to yellowish, often speckled with small white spots.

Could be confused by Hippocampus hippocampus, but this species  has shorter snout, often do not present dermal filaments, and do not present white spots all over its body, sometimes only on the cheek, around the eyes. Identification is especially difficult in the case of young individuals, which still have not its snout fully developed and may not present dermal filaments. They can also be distinguished by the number of dorsal fin rays, with 16-18 in H. hippocampus and 19 or more in the case of H. guttulatus.
