背的軟條 (總數) : 26 - 35. Preorbital bone appears as broad plate in front of eye (Ref. 26938).
眶前骨在眼睛前面中呈現寬的碟。 (參考文獻 26938)
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).
豐富的在海草床中沿著海岸。 北方族群在比較寒冷的數個月期間移動外海。 (參考文獻 26938) 卵胎生的.(參考文獻 205) 雄魚帶卵在一個孵卵袋是在尾部下面發現.(參考文獻 205)
