Description synthétique
Clés d'identification | Morphologie | Morphométrie
Rayons mous dorsaux (Total) : 578 - 629; Rayons mous anaux: 390 - 432; Vertèbres: 204 - 213. This relatively slender species has the following distinct set of characters: dorsal-fin origin anterior to gill opening; with pterygoid teeth; body depth at gill opening 28.8-35.2% of HL; preanal vertebrae 62-71 (mean = 65), total vertebrae 204-213 (mean 207.4) ; preanal lateral-line
pores 63-69; body colouration consisting of zebra-like black and white barring on head grading to complex black and white maze pattern on body (Ref. 82435).
Collected from a single colony, occupying about 100 sq. m with approximately 50 eels at 5-6 m depth. The bottom is fine, silty sand and influenced by a freshwater stream along the adjacent shoreline, about 100 m distance, with the nearest reef formation about 50 m from the site (Ref. 82435).
