Краткое описание
определительные ключи | морфология | морфометрия
колючие лучи спинного плавника (общее число) : 7; членистые (мягкие) лучи спинного плавника (общее число) : 6 - 8; колючие лучи анального плавника: 1; членистые (мягкие) лучи анального плавника: 6 - 8. This small specis is distinguished by the following characters: D2 I,6-8; A I,6-8; pectoral rays 14-17; segmented caudal rays 15-16 in 9/7 pattern; lateral scales 24-27; transverse scale count 7-8; predorsal scales 7-10; opercle has at least two rows of cycloid scales, cheek scaleless; shoulder girdle is smooth; tongue is blunt; upper jaw teeth similar between male and female, in 2-4 rows, very small, sharp and close-set, while outer row teeth larger. Colouration: head and body whitish to yellowish brown, the scale margins edged with brown, presence of a small single or paired brownish spots or small blotches along mid-side of body with posteriormost spot at hypural crease, extending upward onto caudal fin as oval or rounded blotch (Ref. 126575).
Facultative air-breathing in the genus (Ref. 126274); Occurs in brackish waters (Ref. 43239); in intertidal estuarine habitats and river mouths, mud flats and mangroves. A reported small species apparently spawned in May and August and fed mostly on copepods and amphipods. Associated with several Pseudogobius, especially Pseudogobius pocilosoma (Ref. 126575).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00724 (0.00338 - 0.01553), b=3.05 (2.87 - 3.23), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.1 ±0.4 se; based on size and trophs of closest relatives
устойчивость к внешним воздействиям (Ref.
120179): высокий, минимальное время удвоения популяции до 15 месяцев (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
