Short description

Dorsal soft rays (total): 578-629; Anal soft rays: 390 - 432; Vertebrae: 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).

Trophic Level (Ref. 69278)
3.4 ±0.4 se; Based on size and trophs of closest relatives

Resilience (Ref. 69278)
Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.)

Vulnerability (Ref. 59153)
Moderate vulnerability (45 of 100)
