Kort beskrivning
Bestämningsnycklar | Morfologi | Morfometri
Mjukstrålar i ryggfenan (totalt) : 26 - 35. Preorbital bone appears as broad plate in front of eye (Ref. 26938).
Body shape (shape guide): eel-like.
Abundant in seagrass beds along coasts. Northern populations move offshore during colder months (Ref. 26938). Found mostly at 5 m or less (Ref. 126547). 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).
