背面の脊椎 (合計) : 0; 背鰭 (合計) : 38 - 54; 肛門の骨: 0; 臀鰭: 2 - 3. Diagnosis: 41-44 bony rings (mode 43) (Ref. 81680), 19-21 (mode 20) trunk rings (before anus)(Ref. 57226, 81680) and 20-26 tail rings (behind anus)(Ref. 81680). 8.0-9.75 total subdorsal rings, 1.75-3.5, usually 2.5 or more, subdorsal trunk rings and 5.25-7.0, usually 5.75-6.5, subdorsal tail rings (Ref. 81680). Head length 4.8-5.6 (mean 5.2) times in SL (Ref. 57226, 81680). Snout 1.5-1.7 (mean 1.6) times in HL (Ref. 81680). Coloration: general colour of preserved specimens dark brown, but pattern often highly variable within a single sample; lateral part of snout with dark brown blotches or stripes; body plain, blotched or with vague pale mid-lateral trunk stripe; dorsum and belly somewhat paler than flanks; ventral part of head light brown; opercle with numerous small dark brown spots and often a narrow horizontal dark, silvery stripe situated towards upper edge; caudal fin mainly brown with pale edging; other fins hyaline or with fin rays edged with brown; no consistent differences in preserved colouration of various subspecies (Ref. 81680).

Occurs in coastal rivers, streams and estuaries (Ref. 4127, 81680). Found in sea grasses and above sandy substrates in shallow water near shore a.o. (Ref. 81680). Ovoviviparous (Ref. 205). Breeds in fresh water (Ref. 81680). Male carries the eggs in a brood pouch found under the tail (Ref. 205). Eggs develop in the brood pouch for 1-3 weeks, until young of about 1.5 cm TL leave the pouch (Ref. 81680). Maximum reported total length for M. b. aculeatus 17.1 cm (Ref. 81680).

Eggs are attached to a kind of brood pouch, formed by two skin folds on the belly of the male (Ref. 13371).

Estimates based on models

Preferred temperature (Ref. 123201): 25.2 - 28, mean 27.3 °C (based on 171 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00093 (0.00036 - 0.00242), b=3.05 (2.83 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

栄養段階 (Ref. 69278): 3.4 ±0.4 se; based on size and trophs of closest relatives

回復力 (Ref. 120179): 高い, １５か月以下の倍増期間の最小個体群 (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (14 of 100).
