Researchers Sequenced Redfin Waspfish Genome
Scientists successfully assembled the genome and mapped toxin genes of the venomous Paracentropogon rubripinnis.
Updated on Oct. 8, 2026 in Life Sciences
Researchers have assembled the first draft genome and multi-tissue transcriptome of the redfin waspfish, Paracentropogon rubripinnis. This genomic map identifies 92 high-confidence toxin-like genes, providing new insights into the evolution of venom in the species.
Why it matters
Genomic resources for venomous fish remain limited despite the significant pharmacological potential of their toxins. This study provides a foundational dataset that will support future comparative genomic research and the discovery of novel therapeutic compounds.
The assembly spans 919.8 Mb across 421 scaffolds with an N50 of 4.92 Mb and 97.1% BUSCO completeness. Analysis of RNA-seq data from eight tissues identified 900 toxin-homologous genes, which were refined to 92 high-confidence candidates.
The players
Paracentropogon rubripinnis
This species of waspfish is a member of the Scorpaeniformes clade and is noted for its venomous properties.
The details
The team utilized a combination of PacBio long-read and Illumina short-read sequencing to generate the draft genome. Researchers identified 19 specific genes that showed significant expression enrichment in the dorsal spine, linking them to the fish's venom delivery mechanism.

The Big Picture
The study utilizes the vertebrate gene set-based BUSCO completeness framework to validate its genomic assembly at 97.1%. This benchmarking confirms the high quality of the P. rubripinnis draft genome, following standard protocols for modern sequencing efforts.
This research provides the foundational genetic map necessary for identifying potential medical applications of fish venom toxins. These insights could eventually lead to the development of new pharmaceutical drugs derived from the biological compounds identified in the study.
The takeaway
The successful sequencing of the redfin waspfish demonstrates the power of combining long-read and short-read sequencing technologies for non-model organisms. This approach provides a repeatable blueprint for mapping toxin-producing genes in other understudied venomous species.
