In this study, vertebral anomalies particularly malformed neural spine and malformed haemal spines were most frequently observed.
where D1=the first discriminant score of an individual; od=orbit depth divided by HL; iou)=interorbital width divided by HL; pfi=pectoral-fin base depth divided by HL; pZ=pectoral fin length divided by HL; cpuZ=caudal peduncle ventral length divided by HL; p<iZ=predorsal length divided by HL; ppZ=prepectoral length divided by HL; gr=the number of gill rakers on the entire gill arch; llp=ihe number of lateral-line pores; dp=the number of dermal plicae; ap=the number of anal-fin pterygiophores anterior to the first haemal spine; pco=the number of precaudal vertebrae; and cu=the number of caudal vertebrae.
Swim bladder large, with two anterior extensions extending forward to basioccipital on both sides above auditory capsule; two posterior extensions extending into haemal funnel beyond posterior end of body cavity, the roots of two posterior extensions are non-adjacent and two posterior extensions are not well-knit.
8): precaudal vertebrae 11; caudal vertebrae (including terminal element) 16; vertebrae 3-11 with pleural rib articulating with respective parapophyses; twelve pairs of epineurals, articulating with vertebrae as follows: epineurals 1, 2 with corresponding parapophyses, 3-10 with corresponding pleural ribs, epineural 11 reduced and not articulating with pleural rib and 12 highly reduced and embedded in tissue; first caudal vertebra with expanded haemal arch and tiny haemal spine; haemal arch comprising elongate parapophyses, "rib-like" in appearance in lateral view; where parapophyses join ventrally to form haemal arch, a nubbin of bone (haemal spine) projecting posteriorly (Fig.
Last two abdominal vertebrae with bridge of bone connecting haemal arches just distal to their bases, forming 'haemal canal' bounded dorsally by centrum.
Caudal skeleton In early flexion larvae, the notochord begins to bend upward and the haemal spine of the second preural centrum, the fused parhypural plus first and second hypurals, and the third hypural are present (Fig.
2); the spine of the first haemal arch which inserts between the 4th and 5th anal pterygiophores in AUBM OS 3672 (between 3rd and 4th in AUBM OS 3673); and all fins were lightly freckled with melanophores.

For small larvae that had unformed centra, corresponding neural or haemal spines were counted to obtain the number of vertebrae.
However, systematic deposits of calcium phosphate have also been found in chondrocranium, jaws, visceral arches, fin cartilage, claspers, neural and haemal arches (Clement, 1992).
Embedded melanophores appeared near the notochord and neural and haemal spines, and melanophores at the lateral midline of body extended internally from about 8.2 mm BL.
