Etymology: Distoechodon: Greek, dissos, dittos = two + Greek, echo = to carry + Greek, odous = teeth (Ref. 45335);  macrophthalmus: From the Greek 'macros', meaning big or long, and 'ophthalmus', meaning eye, in reference to the large eyes of this species..

Maturity: Lm ?  range ? - ? cm
Max length : 20.0 cm SL male/unsexed; (Ref. 80016)

Short description Morphology | Morphometrics

Dorsal soft rays (total): 10; Anal soft rays: 12. Differs from all its congeners in having the highest number of lateral line scales (78-85, mostly 82), more pre-dorsal scales (34-39, mostly 36), and relatively bigger eye, being 7.97% vs. 6.37-6.98% in SL. Similar to Distoechodon multispinnis in having higher lateral line and predorsal scale counts, but can be easily distinguished by having larger eyes at the same body size (Ref. 80016).

Biology     Glossary (e.g. epibenthic)

Before the 1990s, this species was a very important component of the local fishery. Its population is shrinking quickly. No adult specimen was found during the 2004 field survey. The primary threat might be the introduction of icefishes (Family Salangidae) based on survey conducted (Ref. 80016).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.7500   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00617 (0.00292 - 0.01304), b=3.08 (2.91 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.2   ±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):  Low vulnerability (14 of 100).
