Pegasus draconis   Linnaeus,  1766 (Fish)
Organism information awaits expert curation
Class: Actinopterygii

Size: 100 mm.

Color: In preserved specimens brown, the rostrum and the last caudal ring often darker. Pectorals hyaline with a terminal and a subterminal milky longitudinal band, pectoral spines with brown spots, forming rows. Sometimes the row behind the milky band consists of much larger spots, in other cases these spots are indistinct.

Head and tail less deep than body, the posterior part of the trunk elevated, the fish hence hump back in side view, its greatest height 4.6-5 in length without caudal. Head 2.5-2.7 in length without caudal. Snout 2.25-2.95 in head, slightly spatulate, with a toothed ridge along sides, and two parallel toothed ridges along its upper side. The lower side of the rostrum has a median groove bordered by two rough, but not really toothed low longtudinal ridges, parallel anteriorly, diverging to surround the mouth posteriorly. Greatest breadth at base of pectoral 2.2-2.6 in length without caudal. Two deep pits behind occiput. Two longitudinal ridges on the back, forming blunt tubercles on each dorsal plate. A similar ridge on each side of the trunk, with similar but less developed tubercles. The dorsal ridges are continued on the tail, but as the tail is much less broad than the body they form here the upper edge of the tail, which is quadrangular in cross section. Similar ridges on the lower edges of the tail. The upper and lower tail ridges notched between the rings. A lateral ridge present on each side of the tail in the form of a row of compressed tubercles, one on each of the lateral caudal scutes, present on the first, second, fourth and fifth tail rings. Pectoral rays stiff and spine-like, the fifth not stronger than the others, equal in length to the length of the tail. Caudal truncate, as long as rostrum.

Remarks: Values in above description denote proportions.
