Trichomycterus spectrum is a species of freshwater ray-finned fish belonging to the family Trichomycteridae, the pencil and parasitic catfishes.[2] This catfish was discovered in Alejo cave, Río Ranchería basin, Guajira, Colombia in 2020.[3]

Description

The fish was the first cavefish species discovered in the region. The fish is described as being well adapted to life underground and displays clear troglomorphism.[3]

It grows to a maximum length of 13.19 centimetres (5.19 in) standard length.[4]

Etymology

The colourful sounding specific name spectrum does not allude to a spectrum at all. Instead it relates to its spectral-like appearance and its dark cave habitat.[4][5]
