Common in estuaries and in association with Zostera and other vegetation. Juveniles associate with drifting seaweed (Ref. 12114, 12115). Ovoviviparous (Ref. 205). The male carries the eggs in a brood pouch which is found under the tail (Ref. 205). Used in Chinese medicine (Ref. 12166).

Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00023 (0.00012 - 0.00044), b=3.23 (3.07 - 3.39), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.1 ±0.1 se; based on diet studies.
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (24 of 100) .
