# The genome sequence of the Brown garden snail, Cornu aspersum (O.F.Müller, 1774) (Stylommatophora: Helicidae)

## TL;DR

This paper presents the genome sequence of the Brown garden snail, assembled into 27 chromosomal pseudomolecules as part of a larger project to sequence species in Britain and Ireland.

## Contribution

The paper provides the first high-quality reference genome for the Brown garden snail, including a fully assembled mitochondrial genome.

## Key findings

- The genome assembly is 2,908.45 megabases long, with 98.95% scaffolded into 27 chromosomal pseudomolecules.
- The mitochondrial genome is 14.04 kilobases in length and has been fully assembled.
- The work is part of the Darwin Tree of Life project, which aims to sequence eukaryotic species in Britain and Ireland.

## Abstract

We present a genome assembly from an individual
Cornu aspersum (Brown garden snail; Mollusca; Gastropoda; Stylommatophora; Helicidae). The genome sequence has a total length of 2 908.45 megabases. Most of the assembly (98.95%) is scaffolded into 27 chromosomal pseudomolecules. The mitochondrial genome has also been assembled, with a length of 14.04 kilobases. 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.
