The somatic genome of Eptatretus okinoseanus reveals the adaptation to deep-sea oligotrophic environment.

ABSTRACT:

Background

Hagfishes are fascinating creatures that typically inhabit the deep sea. The deep sea is characterized by its lack of sunlight, primary productivity, and diminishing biomass with increasing ocean depth. Therefore, hagfishes living in this environment must develop effective survival strategies to adapt to the limited food supply. Deep-sea hagfishes have been observed to survive without food intake for up to one year. In this study, we have assembled a high-quality somatic genome of the deep-sea hagfish (Eptatretus okinoseanus) captured below 1,000 m. We compared the genome of E. okinoseanus with the genomes of inshore hagfish, lampreys, and other related species to investigate the genetic factors underlying the deep-sea hagfish adaptations to the environment.
