Etymology: Ancistrogobius: Name from Greek word 'agkistros' meaning fishhook and Gobius , a genus name of gobiine fish, in reference to the short, ventrally directed, spur-like preopercular spine.;  dipus: Name from Greek words 'dis' meaning two and 'pous' for foot. referring to its largely separated pelvic fins.

Short description Morphology | Morphometrics

Dorsal spines (total): 7; Dorsal soft rays (total): 9-10; Anal spines: 1; Anal soft rays: 9. This species is unique from its congeners by having the following characters: largely separated pelvic fin with rudimentary connecting membrane and no frenum; fifth segmented ray of pelvic fin short, length 67.9-71.9% of preceding ray; a narrow black blotch on distal tip of first dorsal fin (not reaching posteriorly to third spine); pectoral-fin rays 19-21, usually 20; head and most of nape naked, no predorsal scales (except for one specimen, WAM-P.32537-001, with one predorsal scale); third spine of first dorsal fin greatly elongated, filamentous, obviously longer than preceding spine, typically with alternating pale and dusky (or yellow) bands when alive or fresh; faint, dusky blotches (not forming distinct vertical bar) below eye; sensory papilla x^1 and x^2 not continuous, interrupted by row trp; sensory papilla rows trp long, extending dorsally to well above a longitudinal line through row x^1; anterior tip of sensory papilla row b meeting row 4; sensory papilla row 4 long, dorsal tip close to eye; possess a relatively slender and pointed snout (this character difficult to quantify) (Ref. 84001).

Biology     Glossary (e.g. epibenthic)

Collected from sandy-mud or silt bottoms with dead-coral rubble at depths of 15-35 m (Ref. 84001).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5625   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00631 (0.00286 - 0.01390), b=3.08 (2.90 - 3.26), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.2   ±0.3 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 vulnerability (12 of 100) .
