[3][4] This species was discovered by scientists exploring the inaccessible and remote region of Aprada-tepui.

It is a fast-moving frog that lives along creeks and in quiet pools along small streams along the slopes near the cave.

[2] The distinctive features of this species are its particular skin pattern, absence of fringes on fingers, moderate toe webbing, tongue characteristics, and yellow and orange coloration on its undersides.

[5] The type series consists of one female (the holotype), two males, and one unsexed juvenile.

[2] Anomaloglossus breweri is only known from a collapsed steep gorge on the northwestern slope of the tepui at an elevation of 660 m (2,170 ft) above sea level.
