Aboral cell types of <i>Clytia</i> and coral larvae have shared features and link taurine to the regulation of settlement.

ABSTRACT: Larval settlement is of interest both for ecologists and for evolutionary biologists, who have proposed that anterior sensory systems for substrate selection provided the basis for animal brains. Nevertheless, the cellular and molecular regulation of settlement, including in Cnidaria (corals, jellyfish, sea anemones, and hydroids), is not well understood. We generated and compared anterior (aboral) transcriptomes and single-cell RNA sequencing datasets from the planula larvae of three cnidarian species: the jellyfish Clytia hemisphaerica and the corals Astroides calycularis and Pocillopora acuta. Integrating these datasets and characterizing aboral cell types, we defined common cellular features of the planula aboral end and identified clade-specific specializations in
