Bramidae•Unknown species flexion of

Bramid•Collected in Bay of Bengal

via bongo net•Measurements:BD: 3.75 mmHL: 1.45 mmED 0.5mmSnL 0.3mmPAL 1.75mmBD 1.4mm•Pigmentation: scattered on

head and trunk; be density over the head and gill cover and around dorsal gut area

•Others: Round head- trunk part. Non visual head spine

Bramidae•Post flexion of Bramid Collected in

Similan Island by ring net oblique trawling.•Measurements:BL: 8.1 mmHL: 2.3 mmED 1.3mmSnL 0.8mmPAL 5.0mmBD 3.3mm•Counts: D: 33 A: 23• P1: 18 P2: I,5• C:21 Myomeres:

NR•Pigmentation: Pigments appear clearly

and small on head and trunk but be gradually to tail base. Mostly concentrative on over head to anterior dorsal fin base and gut areas.

•Head Spine: Serrate preopercular.

Bregmacerotidae•Post flexion stage of unknown species

collected in Western of Kalimantan via bongo net

•Genus: Bregmaceros•Measurements:BL: 8.3 mmHL: 1.4 mmED 0.3mmSnL 0.5mmPAL 3.0mmBD 1.5mm•Counts: D: 1+51 A: 52

P1: 10-13; P2: I- 3C:26 Myomeres:

41-42

Bregmacerotidae (cont.)• Pigmentation: few and small at

pectoral fin base, above gill cover and gut. A big pigment above marginal posterior gut area

• Others: gut coil. Long ray like spine over the head. Pectoral fin nearly horizontal that makes tip of fin ray rises higher body. Pelvic fin elongated within a few ray (3-5) like barbell. Dosal and anal fin ray so tiny and tight that be countable after staining only and continua to caudal fin

• Stylephoridae very similar but fewer anal fin ray, mouth smaller and protrusible (Lesis, 2004).

Engraulidae•Post flexion stage of unknown

species collected in SW-SE Vietnam via bottom trawling net (500Mr)

•Subfamily: Engrauninae•Measurements:BL: 10.65 mmHL: 2.5 mmED 0.5mmSnL 0.7mmPAL 8.4mmBD 1.0mm•Counts: D: 13 A: 14

P1: 9; P2: C:19

Myomeres: 41-42

Engraulidae (cont.)

• Pigmentation: Along the gut and lower posterior of tail base and caudal fin. One behide the eye on gill cover

• Others: Very elongate body and very long gut. Lower jaw is longer than uper jaw. Posterior gut puckers. Gas blader is above midle gut. No head spine

• Similar fam.: Clupeidae (mouth, dorsal and anal fins location…)
