Abstract

Draft Genome of the Mirrorwing Flyingfish (Hirundichthys speculiger).

Highlights

Flying fishes (Exocoetidae; Beloniformes) have evolved with numerous interesting characteristics, such as gliding over water, marine- to freshwater transition, and unique craniofacial and egg buoyancy
The Illumina sequencing generated a total of ∼138.13-Gb raw reads, and 99.21-Gb clean reads were retained after filtering low-quality sequences (Supplementary Table 4)
A k-mer analysis predicted that the mirrorwing flyingfish had an estimated genome size of 1.06 Gb and a heterozygosity of 1.35% (Figure 1B)

Summary

Introduction

Flying fishes (Exocoetidae; Beloniformes) have evolved with numerous interesting characteristics, such as gliding over water, marine- to freshwater transition, and unique craniofacial and egg buoyancy. They have been regarded as an extraordinary marine group with enlarged pelvic fins and hypocercal caudal fins, which could help to glide over water to reach a distance up to 400 m (Davenport, 1994). When the mirrorwing flyingfish leaps out of water, whether it employs the same mechanisms as mudskippers (including crucial mutation sites of LWS, lack of SWS1, and loss of aanat1a in the giant-fin mudskipper; see more details in You et al, 2014) or not is still an open question
