Living animals are dark brown to black. The head and rhinophores are black. The tips of the rhinophores have an opaque white pigment. The parapodia are lined with a series of longitudinal lines of orange, black and blue. These lines are also present along the anterior margin of the foot.
T. livida is most closely related to T. hoffae Gosliner, 1995. The main difference between T. livida and T. hoffae is the narrow iridescent blue submarginal line present on T. livida. Alternatively, T. hoffae has a series of submarginal blue to blue green patches. T. livida has orange and blue lines of the anterior margin of the foot that are absent in T. hoffae. The general body colour is darker in T. hoffae than in T. livida.
