The Indo-Pacific humpback dolphin (Sousa chinensis), is a threatened marine mammal and belongs to the First Order of the National Key Protected Wild Aquatic Animals List in China. However, limited genomic information is available for studies of its population genetics and biological conservation. Here, we have assembled a genomic sequence of this species using a whole genome shotgun (WGS) sequencing strategy after a pilot low coverage genome survey. The total assembled genome size was 2.34 Gb: with a contig N50 of 67 kb and a scaffold N50 of 9 Mb (107.6-fold sequencing coverage). The S. chinensis genome contained 24,640 predicted protein-coding genes and had approximately 37% repeated sequences. The completeness of the genome assembly was evaluated by benchmarking universal single copy orthologous genes (BUSCOs): 94.3% of a total 4,104 expected mammalian genes were identified as complete, and 2.3% were identified as fragmented. This newly produced high-quality assembly and annotation of the genome will greatly promote the future studies of the genetic diversity, conservation and evolution.Design Type(s)sequence assembly objective • sequence annotation objectiveMeasurement Type(s)whole genome sequencing assayTechnology Type(s)DNA sequencingFactor Type(s)Sample Characteristic(s)Sousa chinensis • skin of bodyMachine-accessible metadata file describing the reported data (ISA-Tab format)
