Size / Weight / Age

Maturity: Lm ?  range ? - ? cm
Max length : 18.0 cm SL male/unsexed; (Ref. 9822); common length : 15.0 cm SL male/unsexed; (Ref. 9822)

Short description Morphology | Morphometrics

Dorsal spines (total): 0; Anal spines: 0. Belly with 25 to 28 keeled scutes. Distinguished from all other Thryssa species and anchovies by the very long maxilla, reaching at least to tip of pectoral fin, usually to pelvic fin base or even to anal fin origin; also unique is the high coronoid process of the lower jaw, the jaw rising steeply in the mouth. Head with gold tints; anal and caudal fins deep yellow; dark spot behind gills.

Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

Indo-Pacific: Gulf of Oman south to Port Alfred, no records from the Red Sea and Madagascar; coasts of Pakistan, India, probably Burma; Thailand, Indonesia, Philippines to Taiwan; also the Arafura Sea (Ref. 9819), northern Australia, Papua New Guinea, Solomon Islands and New Hebrides.

Biology     Glossary (e.g. epibenthic)

Presumably schooling occurring mostly (or always ?) close inshore and entering bays and estuaries. Recorded at a temperature range of 26.0-29.0 °C in the Trinity Inlet system, Australia (Ref. 4959). Feeds mainly on crustaceans (zoea larvae, amphipods, Acetes). More data needed, including some functional explanation for the extraordinarily long maxillae. May be caught using ringnets (Ref. 5213). Used as bait in the tuna fishery in the South Pacific.

Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00759 (0.00454 - 0.01270), b=3.19 (3.05 - 3.33), based on LWR estimates for species & Genus-BS (Ref. 93245).
Trophic Level (Ref. 69278):  3.3   ±0.48 se; Based on food items.
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low vulnerability (22 of 100) .
Price category (Ref. 80766):   Medium.
