Etymology: Heteroconger: Greek, heteros = other + Latin, conger = conger (Ref. 45335); mercyae: Named for Mercy Paine, who discovered the eel colony and helped us collect the type specimens.
Eponymy: Mercy Paine (d: 1998) discovered the eel colony and helped the authors to collect the type specimens during a diving cruise with her family. [...] (Ref. 128868), visit book page.

Breve descrizione
Chiavi di identificazione | Morfologia | Morfometria
Raggi dorsali molli (totale) : 578 - 629; Raggi anali molli: 390 - 432; Vertebre: 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).
Body shape (shape guide): eel-like; Cross section: circular.
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).
