Abstract
We present a genome assembly from a specimen of Ammodytes marinus (the lesser sandeel; Chordata; Actinopteri; Uranoscopiformes; Ammodytidae). The genome sequence has a total length of 777.80 megabases. Most of the primary assembly (95.51%) is scaffolded into 25 chromosomal pseudomolecules. The mitochondrial genome has also been assembled and is 16.53 kilobases in length. Gene annotation of this assembly on Ensembl identified 22,410 protein-coding genes.
