Etymology: Omobranchus: Greek, omo = shoulder + Greek, brangchia = gill (Ref. 45335).
Environment / Climate / Range
Marine; brackish; reef-associated; depth range 0 - 3 m (Ref. 90102). Tropical; 28°N - 23°S
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 5.6 cm SL male/unsexed; (Ref. 7050)
Indo-Pacific: Nicobar Islands to Samoa; north to Mariana Is; south to New Caledonia; Palau and eastern Caroline Islands The subspecies Omobranchus rotundiceps rotundiceps (Macleay 1881) occurs in Australia.
Adults inhabit mangroves and sheltered bays (Ref. 90102). Occur among corals, rocks, and rubble of shallow waters (Ref. 1602, 58302). Benthic (Ref. 58302). Oviparous. Eggs are demersal and adhesive (Ref. 205), and are attached to the substrate via a filamentous, adhesive pad or pedestal (Ref. 94114). Larvae are planktonic, often found in shallow, coastal waters (Ref. 94114).

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01122 (0.00514 - 0.02450), b=3.04 (2.87 - 3.21), based on all LWR estimates for this body shape (Ref. 93245
Trophic Level (Ref. 69278
): 2.7 ±0.2 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (10 of 100) .
