Etymology: Ituglanis: Greek, itys, ityos = circle + Greek, glanis = a fish that can eat the bait without touching the hook; a cat fish (Ref. 45335); boitata: The specific name boitata comes from the indigenous language Tupi-Guarani 'boi' (snake) and 'tata' (fire), in reference to the orangish coloration and to the species swimming behavior that resembles a snake. 'Boitata' snake is part of several fictitious tales in the Brazilian culture popularized in the Rio Grande do Sul State by the writer Simões Lopes Neto.
