Occurs in rivers with tidal influence. Found in association with submerged aquatic macrophytes, primarily the eelgrass Zostera capensis (Ref. 26174). Sympatric with Syngnathus acus in the eelgrass beds (Ref. 26174). Ovoviviparous (Ref. 205). The male carries the eggs in a brood pouch which is found under the tail (Ref. 205).
出現於受潮汐影響的河川。 發現於鄰近水下的水生大型植物, 主要地鰻草 Zostera capensis.(參考文獻 26174) 在鰻草床與 Syngnathus acus 重疊分佈了。 (參考文獻 26174) 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)

50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00028 (0.00012 - 0.00065), b=3.21 (3.03 - 3.39), in cm total length, based on LWR estimates for this Genus-body shape (Ref.

營養階層 (Ref.
69278): 3.2 ±0.5 se; based on size and trophs of closest relatives
回復力 (Ref.
