Embryonic development of the Mediterranean starfish Hacelia attenuata
Developmental Dynamics, EarlyView.Abstract Background Starfish play essential ecological roles as predators and ecosystem regulators; however, detailed developmental descriptions exist for only a handful of species, none of which are from the Mediterranean Sea. Results In this study, we provide the first full account of the development of the Mediterranean starfish Hacelia attenuata ...

Genomic and single cell insights into the metamorphosis of the crinoid A. mediterranea
, 2023 Many marine animals have the striking ability to generate different body plans out of the same genome during their life cycle: the larva and the adult.

Developmental Dynamics, EarlyView.Abstract The sea anemone, Nematostella vectensis, has been used as a model organism in developmental biology studies for many years. This estuarine species has the notable capacity to regenerate its full body plan from small pieces throughout life. Nematostella have been described as having a great degree of cellular plasticity.

Phanogracilins A–C, New Bibenzochromenones of Crinoid Phanogenia gracilis (Hartlaub, 1890)
BiomoleculesThree new bibenzochromenones named phanogracilins A–C (1–3) were isolated from the crinoid Phanogenia gracilis. The structure of 1 was established using X-ray crystallography as 5,5′,6,6′,8,8′-hexahydroxy-2,2′-dipropyl-4H,4′H-[7,9′-bibenzo[g]chromene]-4 ...

Geological Journal, EarlyView.In this study, we re‐examine the depositional architecture of the Erfoud limestone in Morocco. Introducing new biostratigraphic constraints from chitinozoan assemblages, we show that Katian to Hirnantian bryozoan‐pelmatozoan meadows reflect flooding events linked to a series of interglacial transgressions known to have occurred immediately prior to the

Palaeobiogeography of Ordovician echinoderms [PDF]
, 2013 The palaeobiogeographical distribution of the six major clades of Ordovician echinoderms (asterozoans, blastozoans, crinoids, echinozoans, edrioasteroids and stylophorans) is analysed based on a comprehensive and up-to-date database compiling 3701 ...

Tool Use by Four Species of Indo-Pacific Sea Urchins
Journal of Marine Science and Engineering, 2019 We compared the covering behavior of four sea urchin species, Tripneustes gratilla, Pseudoboletia maculata, Toxopneustes pileolus, and Salmacis sphaeroides found in the waters of Malapascua Island, Cebu Province and Bolinao, Panagsinan Province ...

Ecology and Evolution, 2020 Organisms have limited resources available to invest in reproduction, causing a trade‐off between the number and size of offspring. One consequence of this trade‐off is the evolution of disparate egg sizes and, by extension, developmental modes.
