Abstract
We present a genome assembly from a juvenile female Lagenorhynchus albirostris (the white-beaked dolphin; Chordata; Mammalia; Artiodactyla; Delphinidae). The genome sequence has a total length of 2,544.80 megabases. Most of the assembly is scaffolded into 22 chromosomal pseudomolecules, including the X sex chromosome. The mitochondrial genome has also been assembled and is 16.39 kilobases in length.
