The genome sequence of the Greater sandeel, Hyperoplus immaculatus (Corbin, 1950) (Uranoscopiformes: Ammodytidae)

We present a genome assembly from an individual <i>Hyperoplus immaculatus</i> (Greater sandeel; Chordata; Actinopteri; Uranoscopiformes; Ammodytidae). The genome sequence has a total length of 797.79 megabases. Most of the assembly (91.28%) is scaffolded into 24 chromosomal pseudomolecules. The mitochondrial genome has also been assembled, with a length of 16.53 kilobases. Gene annotation of this assembly on Ensembl identified 22 130 protein-coding genes. This assembly was generated as part of the Darwin Tree of Life project, which produces reference genomes for eukaryotic species found in Britain and Ireland.
