Are interphylum spiralian relationships resolvable? The phyla making up the major animal clade of Spiralia have been clear since the advent of molecular phylogenetics; the relationships between these spiralian phyla have not. The lack of consensus over the relationships between these important animal phyla might be a clue implying their emergence in an explosive radiation. Focusing on the five largest spiralian phyla (Annelida, Brachiopoda, Mollusca, Nemertea and Platyhelminthes) and using two phylogenomic datasets, we have applied site-bootstrapping and taxon-jackknifing to explore this example of taxonomic instability. Analyses on the 105 possible rooted trees relating them showed that interphylum branches are very short. Preference for rooting Spiralia on Platyhelminthes is a long-branch artefact. Most analyses on the 15 unrooted trees showed a preference for the same topology but the support over other solutions was non significant. We conclude that the spiralian phyla emerged in rapid succession resulting in a difficult to resolve radiation. The deep history we infer for Spiralia has wide ranging implications for our interpretation of Cambrian fossils and for the evolution of traits such as biomineralization, segmentation and larvae. Impact Statement Analyses of two independent phylogenomic datasets suggest an explosive radiation at the origin of Spiralia, with implications for understanding the group’s evolutionary history. ### Competing Interest Statement The authors have declared no competing interest.

GBE | The Chromosome-Scale Genome Assembly of the Redlip Blenny, Ophioblennius macclurei (Blenniidae)

The article by Kulikov et al. presents the chromosome-scale genome of the red lip blenny (Ophioblennius macclurei). This resource could help better understand the cryptic diversity and species boundaries within the genus. Photo by: Evan D’Alessandro.

Kulikov, @ikeririsarri.bsky.social @fonamental.bsky.social et al present a 529.6 Mb chromosome-scale genome for the redlip blenny (scaffold N50 = 23.7 Mb; BUSCO = 97.06%). Annotation identified 18,927 protein-coding genes.
