As mentioned above, five other pipefishes are found in the IRL. Of these, one is a long-snout species like S. louisianae. The dusky pipefish, S. floridae, is generally smaller than S. louisianae, at a maximum length of 25 cm (Robins & Ray 1986). The body is olive-brown and variably mottled without districts bands. The dorsal fin is usually located from the 2nd trunk ring to the 4th or 5th tail ring. Other fin ray and meristic counts are as follows: dorsal fin rays = 26-34; trunk rings = 17-18; and tail rings = 30-38 (Robins & Ray 1986). The commonly seen gulf pipefish, S. scovelli, is a short-snout species only reaching 7.5 cm in length. Regional Occurrence & Habitat Preference: The range of the chain pipefish extends from Virginia to the Caribbean coast of Mexico, Jamaica, Bermuda, and the Gulf of Mexico. However, this species is reported to be absent from the Bahamas (Robins & Ray 1986). Most populations of S. louisianae inhabit seagrass beds, marsh areas (Kanouse et al. 2006) and floating mats of the brown algae Sargassum natans and S. fluitans (Wells & Rooker 2004).
