Etymology: Oxyurichthys: Greek, oxys = sharpen + Greek, oura = tail + Greek, ichthys = fish (Ref. 45335); zeta: Name from the Greek ζήτα (zeta) which gave rise to the last letter of the Roman alphabet u; this elusive species is known from only two specimens and several photographs and is the last species in this revision, although it is unlikely to be the last species described for this genus.
Environment: milieu / climate zone / depth range / distribution range
Marine; demersal; depth range 12 - 38 m (Ref. 103856). Subtropical
Pacific Ocean: from Japan, Palau, Indonesia, Papua New Guinea and the Solomon Islands.

Morphology | Morphometrics
soft rays: 13. This species is distinguished by the following characters: dorsoposterior of eye without tentacle, cornification or spot; no constriction at premaxillary symphysis of upper lip; first dorsal-fin spines are short, posteriormost spines reaching just beyond second element of second dorsal fin when appressed; anterior nares in small tube and not darkly pigmented; nape has a low membranous crest; absence of gular spots; not spots on scales on dorsum; when alive, with a large blackish blotch on posterior part of first dorsal fin and 4 large diffuse spots along the mid-side of body and one spot on caudal-fin base, also indistinct; no saddle on caudal peduncle; cycloid (reduced ctenoid) scales; naked prepelvic region; lateral scales 100-112; pectoral-fin rays 22; pelvic fins are dusky, not barred or mottled (Ref. 103856).
Specimens are photographed hovering over a dark soft substrate. One individual at Lovina Beach, Bali, appears to be at the entrance of a large burrow (made by another organism).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00708 (0.00318 - 0.01574), b=3.00 (2.82 - 3.18), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.4 ±0.5 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
): Low vulnerability (11 of 100) .
