Etymology: Syngnathus: Greek, syn, symphysis = grown together + Greek, gnathos = jaw (Ref. 45335). More on authors: Jordan & Gilbert.
Environment: milieu / climate zone / depth range / distribution range
Marine; demersal; depth range ? - 22 m (Ref. 26938), usually ? - 4 m (Ref. 26938). Subtropical; 40°N - 8°N
Western Atlantic: disjunct distribution from Bermuda and Chesapeake Bay (USA), including the northern Gulf of Mexico, the Bahamas, and the western Caribbean Sea (Ref. 37039), to Panama.

Morphology | Morphometrics
(total): 26-35. Preorbital bone appears as broad plate in front of eye (Ref. 26938).
Abundant in seagrass beds along coasts. Northern populations move offshore during colder months (Ref. 26938). Ovoviviparous (Ref. 205). The male carries the eggs in a brood pouch which is found under the tail (Ref. 205). Feeds mostly on small grass shrimp and other small crustaceans (Ref. 93252).
