They have a moderate-sized head, a rounded caudal fin, long snout and a small terminal mouth. The dorsal fin is moderate in length, the anal fin is greatly reduced, and the pelvic fins do not exist. The abdomen is flat or concave and may have a very small keel. The inferior trunk and tail ridges are not interrupted. Males have a brood pouch along the tail. There are 33-36 dorsal rays, 2 anal rays, 14 pectoral rays, 20 trunk rings, and 35-36 tail rings. The chain pipefish is one of the largest species of pipefishes in the western North Atlantic, with a maximum length of 381mm (15 in). The coloration of the chain pipefish, generally has a light colored background that is white to light brown. There is a dark brown stripe along the sides that extends onto the snout. There are lighter circular bands around the body between each body ring. The circular bands do not extend onto the ventral surface in the trunk area, but are visible along the tail. The anal, pectoral, and dorsal fins are generally unpigmented, but may have some scattered melanophores. The caudal fin is dusky.
