The lined seahorse, Hippocampus erectus is a large deep-bodied seahorse (Lourie et al. 1999) with a variable body color. Individuals can be olive-brown, ash gray, orange, red, black or yellow (Lourie et al. 2004, Robins & Ray 1986). Many have white lines following the contour of the neck, contrasting saddles across the dorsal surface and tiny white dots on the tail. Some specimens, especially those living amongst brown Sargassum algae, bare fleshy tabs and protuberances that serve as camouflage (Robins & Ray 1986). The coronet on the top of the head forms a low, triangular wedge with sharp edges. The 1st, 3rd, 5th, 7th and 11th trunk rings may be raised and enlarged. Cheek spines may be single or double, and the snout is usually less than one-half the head length. One tail and two trunk rings support the dorsal fin. Fin rays and other meristic counts are as follows: trunk rings = 11; tail rings = 34-39; dorsal fin rays = 16-20; pectoral fin rays = 14-18 (Lourie et al. 2004).
