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. More on authors: Zhao, Kullander, Kullander & Zhang.
Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic. Tropical
Asia: known only from the Chenhai Lake, Chang Jiang basin in Yunnan Province, China.

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).
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).

= 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00575 (0.00268 - 0.01234), b=3.10 (2.92 - 3.28), 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
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Moderate vulnerability (36 of 100) .
