Etymology: Spectracanthicus: Latin, spectrum = look, apparition + Greek, akantha = thorn (Ref. 45335); zuanoni: Named for Jansen Zuanon (INPA) due to his contribution to the knowledge of Neotropical Ichthyology. Jansen Zuanon was also the first ichthyologist who collected and identified this species as a new one.
Eponymy: Dr Jansen Alfredo Sampaio Zuanon is a Brazilian ichthyolgist and ecologist. [...] (Ref. 128868), visit book page.

Breve descrizione
Chiavi di identificazione | Morfologia | Morfometria
Raggi dorsali molli (totale) : 8; Raggi anali molli: 5; Vertebre: 26. This is distinguished from other species of Spectracanthicus by its color pattern consisting of large, white spots (vs. small yellowish dots in S. murinus, S. punctatissimus, and S. tocantinensis , and dark gray lacking dots in S. immaculatus). It also differs from congeners, except S. murinus, by having larger orbital diameter up to 29.2% of HL (vs. up to 25.7% in S. punctatissimus, 20.3% in S. tocantinensis, 16.2% in S. immaculatus). It can be further separated from S. murinus by having rounded dorsal view of the snout, bar-shaped, eversible opercle with conspicuous odontodes, and four unbranched anal-fin rays (vs. snout slightly pointed; opercle triangle-shaped, not eversible, lacking conspicuous odontodes; three anal-fin unbranched rays); from S. tocantinensis by having 19-43 dentary teeth (vs. 8-16) and by the infraorbital 4 forming just a small area of orbit (vs. forming posterior edge of orbit almost totally) (Ref. 95496).
Body shape (shape guide): fusiform / normal.
Feeds actively at night on algae and other food items off periphyton by grazing over rock bottom. Found in rock-bottom areas subjected to backwater and strong currents. Occurs individually or in groups of three, under shelter boulders (adults) and spaces beneath rocks (juveniles), up to 2m deep. Juveniles co-inhabit with other loricariids such as Ancistrus sp., A. ranunculus, Baryancistrus xanthellus, Spectracanthicus punctatissimus , Hopliancistrus tricornis, Parancistrus nudiventris, Peckoltia vittata, and Pseudancistrus aff. barbatus (Ref. 95496).
