All Fishes Data Sheet
Scientific Name	**Spectracanthicus murinus** Nijssen & Isbrücker, 1987
Common Name
Type Locality	Poça de Pedra, Rio Tapajós, eastern Pará, Brazil.
Etymology	Genus: Latin, spectrum = look, apparition + Greek, akantha = thorn. This specific epithet literally means mouse gray (murinus=mouse gray) and refers to its colour.
Species Information
Size	64mm or 2.5" SL. Find near, nearer or same sized spp.
Identification	Spectracanthicus can be separated from all other loricariids except some Baryancistrus, Parancistrus and an undescribed Hemiancistrus by the presence of the dorsal-fin membrane contacting the adipose-fin spine. It can be separated from Baryancistrus and the Hemiancistrus by having fewer teeth (less than 25 vs. greater than 25) and from Parancistrus by having restricted gill openings. A key to the genus can be found here. Spectracanthicus murinus is unique among Ancistrini in that it has lost the evertible cheek plates typical of species of Ancistrini.
