title: The genome of the miiuy croaker reveals well-developed innate immune and sensory systems.
abstract: The miiuy croaker, Miichthys miiuy, is a representative Sciaenidae known for its exceptionally large otoliths. This species mainly inhabits turbid aquatic environments with mud to sandy mud bottoms. However, the characteristics of the immune system of this organism and its specific aquatic environment adaptations are poorly understood. Thus, we present a high-quality draft genome of miiuy croaker. The expansions of several gene families which are critical for the fish innate immune system were identified. Compared with the genomes of other fishes, some changes have occurred in the miiuy croaker sensory system including modification of vision and expansion of taste and olfaction receptors. These changes allow miiuy croaker to adapt to the environment during the long-term natural selection. The genome of miiuy croaker may elucidate its relatively well-developed immune defense and provide an adaptation model of the species thriving in turbid deep aquatic environments.
