Etymology: Symphurus: Greek, syn, symphysis = grown together + Greek, oura = tail (Ref. 45335); maculopinnis: The specific name, maculopinnis, from the Latin macula, meaning spot, and pinna, meaning fin, referring to the conspicuous spots on the dorsal and anal fins of this species; noun in apposition (Ref. 87974).
Ambiente: milieu / zona climatica / distribuzione batimetrica / gamma di distribuzione
Ecologia
marino benthopelagico; distribuzione batimetrica ? - 561 m (Ref. 87974). Tropical; 24°S - 25°S, 177°W - 178°W
Western Pacific: Tonga Arc, Volcano-19. Tunnicliffe et al., 2010 (Ref. 88005) indicated that this species was also observed at shallower depths (between 195-381 m) at a second, nearby site (Volcano-1). However, re-examination of photographs indicates that the individuals upon which these observations were based can not be positively identified. Thus, reported occurrences of S. maculopinnis both at Volcano-1 and at these shallower depths is tenuous (Ref. 87974).

Breve descrizione
Chiavi di identificazione | Morfologia | Morfometria
Symphurus maculopinnis is distinguished from all other species of Symphurus by the combination of a 1–2–2–2–1 ID pattern, 14 caudal-fin rays, 3+6 abdominal vertebrae, 49 total vertebrae, about 89 scales in a longitudinal row, 92 dorsal-fin rays, 77 anal-fin rays, a blunt squarish snout, blind-side lower jaw with thick lip with conspicuous plicae, and by conspicuous ocellated (sometimes partially) black spots on the posterior dorsal and anal fins (Ref. 87974).
Body shape (shape guide): fusiform / normal; Cross section: compressed.
Known only from the holotype, collected on soft sediments at 561 m; 56 other individuals observed, but not collected, were found on a variety of substrata, including coarse gravel, gravelly sand-shell and gravelly sand, located between 433-561 m on Volcano-19, Tonga Arc, western Pacific. Considered to be a true vent species since (Ref. 87974).
