Etymology: Synodus: Greek, syn, symphysis = grown together + Greek, odous = teeth (Ref. 45335). More on author: Schultz.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 1 - 88 m (Ref. 86942), usually 1 - 10 m (Ref. 11228). Tropical; 26°N - 24°S
Indo-Pacific: Gulf of Aden and East Africa to the Hawaiian and Gambier islands, north to the Ogasawara Islands, south to the Great Barrier Reef.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 18.0 cm TL male/unsexed; (Ref. 11228); common length : 10.0 cm TL male/unsexed; (Ref. 3520)
soft rays: 8 - 10. Cheek behind mouth scaled; palatine teeth in a single band on each side (characteristic of the genus); membranous flap on anterior nostrils long and broad; dorsal tip of snout with a pair of small but prominent black spots (Ref. 2334).
Occurs in coral reefs (Ref. 11228). Benthic (Ref. 58302). Generally solitary and typically rests on hard surfaces, occasionally with a head down position on a steep slope (Ref. 1602). Feeds on small fishes and shrimps (Ref. 89972). Sold fresh in markets.

Estimates based on models
Preferred temperature (Ref. 115969
): 25.3 - 29.3, mean 28.4 °C (based on 3181 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00457 (0.00217 - 0.00962), b=3.16 (2.98 - 3.34), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245
Trophic level (Ref. 69278
): 4.0 ±0.7 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (15 of 100) .
