Analysis Of Aboral Spine Variation In The Forcipulate Sea Star, Pisaster Ochraceus (Brandt 1835), Angela Jordane Jones
Theses and projects
Rocky intertidal zones are highly dynamic environments that exhibit substantial spatial and temporal variation in abiotic conditions, which can drive body form variation and energy allocation within calcifying species. Wave exposure, specifically, has been shown to be a significant driver of skeletal and structural morphology in organisms including gastropods, bivalves, and sponges. Many of such organisms, from sponges to echinoderms, rely on calcium carbonate for structural support and protection.
In the phylum Echinodermata (named for possessing a ‘spiny skin’), research on the form and function of calcium carbonate spines is largely relegated to Class Echinodea (e.g., urchins and sand ...
