The genome sequence of the common limpet, Patella vulgata (Linnaeus, 1758).

We present a genome assembly from an individual Patella vulgata (the common limpet; Mollusca; Gastropoda; Patellogastropoda; Patellidae). The genome sequence is 695.4 megabases in span. Most of the assembly is scaffolded into 9 chromosomal pseudomolecules. The mitochondrial genome has also been assembled and is 14.93 kilobases in length. Gene annotation of this assembly on Ensembl identified 19,378 protein coding genes.

Genome sequence for the thick topshell, Phorcus lineatus (da Costa, 1778).

We present a genome assembly from an individual Phorcus lineatus (the thick topshell; Mollusca; Gastropoda; Trochida; Trochidae). The genome sequence is 958 megabases in span. Most of the assembly (99.9%) is scaffolded into 18 chromosomal pseudomolecules. The mitochondrial genome has also been assembled and is 19.1 kilobases in length.

The genome sequence of the Gelatinous Scale Worm, Alentia gelatinosa (Sars, 1835).

We present a genome assembly from an individual Alentia gelatinosa (Gelatinous Scale Worm); Annelida; Polychaeta; Phyllodocida; Polynoidae). The genome sequence is 1,237.5 megabases in span. Most of the assembly is scaffolded into 15 chromosomal pseudomolecules. The mitochondrial genome has also been assembled and is 15.37 kilobases in length.

The genome sequence of the European flat oyster, Ostrea edulis (Linnaeus, 1758).

We present a genome assembly from an individual Ostrea edulis (the European flat oyster; Mollusca; Bivalvia; Ostreida; Ostreidae). The genome sequence is 894.8 megabases in span. Most of the assembly is scaffolded into 10 chromosomal pseudomolecules. The mitochondrial genome has also been assembled and is 16.35 kilobases in length.

The genome sequence of the light-bulb sea squirt, Clavelina lepadiformis (Müller, 1776).

We present a genome assembly from an individual Clavelina lepadiformis (the light-bulb sea squirt; Chordata; Ascidiacea; Aplousobranchia; Clavelinidae). The genome sequence is 210.1 megabases in span. Most of the assembly is scaffolded into 9 chromosomal pseudomolecules. The mitochondrial genome has also been assembled and is 14.48 kilobases in length.
