The tomato hind, Cephalopholis sonnerati, is a bottom-dwelling coral reef fish, which is widely distributed in the Indo-Pacific and Red Sea.C.sonnerati also features complex social structures and behaviour mechanisms.Here, we present a high-quality, chromosome-level genome assembly for C.

sonnerati that was derived using PacBio sequencing and Hi-C technologies.A 1043.66 Mb genome with an N50 length chainsaw file of 2.49 Mb was assembled, produced containing 795 contigs assembled into 24 chromosomes.

Overall, 97.2% of the complete BUSCOs were identified in the genome.A total of 26,130 protein-coding genes were predicted, of which 94.26% were functionally annotated.

Evolutionary analysis revealed that C.sonnerati diverged from its common ancestor with E.lanceolatus and E.akaara approximately 41.

7 million years ago.In addition, comparative genome analyses indicated that the expanded gene families were highly enriched in the sensory hobbit door for sale system.Finally, we found the tissue-specific expression of 8108 genes.We found that these tissue-specific genes were highly enriched in the brain.

In brief, the high-quality, chromosome-level reference genome will provide a valuable genome resource for studies of the genetic conservation, resistance breeding, and evolution of C.sonnerati.
