Sea Biscuit – Marine Specimen
This natural sea biscuit specimen provides a sturdy example of echinoderm structure for homeschool and classroom marine science studies. Similar in form to sand dollars but thicker and more domed, the sea biscuit allows students to observe differences in body shape within related ocean organisms.
Students can examine the raised central profile, five-part radial pattern, surface pores, and rigid calcareous test while discussing marine classification and ocean ecosystems. Its durable structure makes it well-suited for hands-on observation and comparative specimen work.
