High hydrostatic pressure, low temperature, and scarce food supply are the major factors that limit the survival of vertebrates in extreme deep-sea environments. Here, we constructed a high-quality genome of the deep-sea Muddy arrowtooth eel (MAE, Ilyophis

The new synaphobranchid eel Ilyophis singularis is described on the basis of two specimens (248–270 mm in total length) collected from the northeastern South China Sea at a depth between 1,612 and 1,665 m. The new species is characterized by a low number
