Ilyophis brunneus commonly known as the muddy arrowtooth eel, is a species of cutthroat eel in the family Synaphobranchidae. It is found in deep-sea environments worldwide at depths exceeding 1,000 meters. This species is characterized by its elongated body and can grow up to 160 cm in length. As a benthic predator, it plays a significant role in deep-sea ecosystems by feeding on smaller fish and invertebrates, contributing to the trophic dynamics of its habitat.
