Etymology: Heteroconger: Greek, heteros = other + Latin, conger = conger (Ref. 45335);  fugax: Name means 'shy' in Greek, referring to their bashful nature (withdrawing rapidly into their burrow)..

Short description Morphology | Morphometrics

Vertebrae: 197. This species is distinguished by the following set of characters: the body is extremely slender, with depth 1.2% TL and 1.0% TL at gill opening and anus, respectively; pre-dorsal-fin vertebrae 8 and pre-anal-fin vertebrae 67, total vertebrae 197; origin of dorsal fin slightly posterior to tip of appressed pectoral fin; chin with numerous small conical cirri; lateral line with 2-3 rows of dark spots above and below; interorbital space with 6-7 rows of dark spots; a large distinct white rectangular blotch on opercle; number and density of spots on head greater than those on body; lips spotted; ground color of body uniformly cream, no microscopic dark speckles (Ref. 121479).

Biology     Glossary (e.g. epibenthic)

This species forms colonies in muddy bottoms at depths of ca. 30 m off Amami-oshima island (its type locality). Photographic records from other localities were taken over sandy bottoms at depths of 10-12 m. Although sometimes exiting vertically more than 30 cm from their burrows, when approached, individuals immediately disappeared into the burrow with their head holding steadily at ca. several centimeters depth (visible from directly above the burrows). About 40 individuals were estimated for each colony, from a combination of underwater photographs and number of burrows (Ref. 121479).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = No PD50 data   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00102 (0.00046 - 0.00225), b=3.06 (2.88 - 3.24), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.4   ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Moderate to high vulnerability (49 of 100).
