Short description Morphology | Morphometrics

Vertebrae: 162 - 167. An elongate, finless species of sphagebranchin ophichthine (sensu McCosker 1977) with: tail 45-57% and head 5-5.5% of total length; 3 preopercular pores and 3 pores in supratemporal canal; teeth conical, uniserial on jaws and vomer; body mostly pale in preservative, creamy dorsally and reddish-brown ventrally with light and dark head markings in life; and mean vertebral formula 82–164, total vertebrae 162–167. Anterior nostril within an elongate tube, approximately 1/2 the diameter of the eye, its base about midsnout and anterolaterally directed when viewed from above. Posterior nostril opens in outer lip beneath anterior margin of eye. Branchial openings low, ventral; branchial region modestly expanded, creating a bulbous region in posterior half of head (Ref. 75631).

Biology     Glossary (e.g. epibenthic)

Occurs over sand with associated rock and coral reef bottoms and collected with ichthyocides and dredges at depths between 12-100 m (Ref. 75631).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5001   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00148 (0.00060 - 0.00363), b=2.91 (2.70 - 3.12), based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.9   ±0.6 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low to moderate vulnerability (26 of 100) .
