“…As the mechanism of skeletogenesis and digestive tract formation in echinoplutei is conserved across the Echinoidea (Arnone et al, 2015), we expected that the four species would have a similar response to Gd, exhibiting similar phenotypes. On the other hand, due to differences in the extent of skeletogenesis between the species we expected that there might be some differences in absolute sensitivity levels.…”

“…Within deuterostomes, echinoderms are a member of the phylogenetic sister group to chordates, making them an ideal model for understanding the origin and diversification of deuterostome and chordate cell types ( Arnone et al, 2015 ). Sea urchin embryos and larvae have also been extensively used to unravel the general mechanisms of cell type specification and differentiation during development ( Cameron and Davidson, 1991 ; Davidson et al, 1998 ; McClay, 2011 ; Lyons et al, 2012 ; McClay et al, 2020 ).…”

Identifying the molecular fingerprint of organismal cell types is key for understanding their function and evolution. Here, we use single cell RNA sequencing (scRNA-seq) to survey the cell types of the sea urchin early pluteus larva, representing an important developmental transition from non-feeding to feeding larva. We identify 21 distinct cell clusters, representing cells of the digestive, skeletal, immune, and nervous systems. Further subclustering of these reveal a highly detailed portrait of cell diversity across the larva, including the identification of neuronal cell types. We then validate important gene regulatory networks driving sea urchin development and reveal new domains of activity within the larval body. Focusing on neurons that co-express Pdx-1 and Brn1/2/4, we identify an unprecedented number of genes shared by this population of neurons in sea urchin and vertebrate endocrine pancreatic cells. Using differential expression results from Pdx-1 knockdown experiments, we show that Pdx1 is necessary for the acquisition of the neuronal identity of these cells. We hypothesize that a network similar to the one orchestrated by Pdx1 in the sea urchin neurons was active in an ancestral cell type and then inherited by neuronal and pancreatic developmental lineages in sea urchins and vertebrates.

“…suavia, B. boschmai, A. bennetti, C. schlegelii, H. robustipinna, C. bella, and C. multifidus. The morphology of lilies, with their limbs enclosing the mouth facing upward away from the lily-shaped substrate, and their propensity to adhere to rough substrates such as jetty wood make this area suitable for their survival (Arnone et al 2015).…”

“…In general, Echinodermata is one of the largest phyla in the group of invertebrates that includes starfish (Asteroidea), sea lilies (Crinoidea), brittle stars, sea urchins, basket stars (Ophiuroidea), sand dollars (Echinoidea), and sea cucumbers (Holothuroidea) (Espinoza-Rodríguez et al 2021). The Echinoderm (in Greek, echino means hedgehog inhabiting them, and derma means skin) diversity comprises animals with a thorny skeleton and radial and pentameral symmetry (Arnone et al 2015). Echinoderms inhabit diverse benthic habitats, ranging from intertidal to deep sea (Reich et al 2015).…”

Abstract. Siburian RHS, Tapilatu JR, Tapilatu ME. 2023. Discovery of habitat preferences and community structure of Echinoderms in Kri, Raja Ampat, Indonesia. Biodiversitas 24: 3968-3976. Raja Ampat, located in Papua, Indonesia, is home to one of the most diverse coral reef ecosystems and is a component of the Coral Triangle. The coral in Raja Ampat is still considered to be in good health. Although the marine fauna in Raja Ampat is pristine and diverse, there have still only been a few studies in this region. The scientific research on the Echinoderms in Raja Ampat is limited, particularly as a primary input for data research. In this study, we present Echinoderm's habitat and community structure in the Kri coastal area at Mansuar Island based on the data collected at field sampling. From January to February 2023, data were collected intensively during morning and afternoon low tide for three repetitions each, at 5-10 m depths. We conducted morphological species identification. Asteroidea, Holothuroidea, Echinoidea, and Crinoidea were found to be the four major classes of Echinodermata that dominated the sampling area, with a total of 20 species and 180 individuals. Each Echinodermata species has its preferred Kri coastal habitat based on its food supply, unique behavior, and body structure. In addition, the result indicates that this region has a moderate diversity level, with low dominance and moderate to high uniformity. This research provides new information on the ecology of Echinoderms in eastern Indonesia, particularly in Raja Ampat.
