This study by John Starmer and Gustav Paulay from the Florida Museum of Natural History investigates the ossicle variation in Stichopus species, focusing on S. horrens and S. chloronotus. The research employed techniques such as whole mount analysis and measurements of ossicle size, underscoring the morphological differences including tentacle structure and skin features. The findings aim to broaden the understanding of ossicle function and variation across species and ontogeny, paving the way for future multivariate analyses and character exploration in the Stichopodidae family.

Next steps • Explore function (constraints?) on ossicles • Expand presence/absence study (species & ontogeny) • Apply multivariate analysis for measurement-based approach • Look for more characters
