Biology     Glossary (e.g. epibenthic)

Common in eelgrass of bays and estuaries, sometimes taken in shallow offshore waters (Ref. 5316). Feeds on crustaceans (Ref. 6885). Females larger than males (R.C. de Graaf, pers. Comm., 2001; Ref. 93899). Ovoviviparous (Ref. 205). The male carries the eggs in a brood pouch which is found under the tail (Ref. 205).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

A female wraps herself around a male in a rigid vertical S position. Eggs are fertilised in the brood pouch of the male (Ref. 6885).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00033 (0.00017 - 0.00066), b=3.09 (2.92 - 3.26), in cm Total Length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.2   ±0.40 se; Based on food items.
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (tmax=2;).
Vulnerability (Ref. 59153):  Low vulnerability (18 of 100) .
