This preserved sand dollar (Echinarachnius parma) is a formalin-preserved marine invertebrate specimen commonly used in classrooms and laboratories to study echinoderm anatomy and marine biology. Its flattened body form and distinct internal structures make it an excellent model for invertebrate anatomy and comparative biology instruction.
Specimen Details
Common name: Sand dollar
Scientific name: Echinarachnius parma
Size: Varies by specimen
Preservation method: Formalin-preserved
Habitat: Sandy seafloor in coastal marine environments
Collection method: Hand-collected
Quantity: Sold individually
Educational Applications
Commonly used in marine biology and invertebrate zoology courses, this specimen supports instruction in echinoderm body structure, radial symmetry, and feeding mechanisms. Students can examine both external morphology and internal anatomical features.
Anatomical Features
Flattened echinoderm body adapted to sandy habitats
Rigid test with characteristic petaloid pattern
Internal structures suitable for anatomical study
Suitable for invertebrate anatomy and marine biology instruction
Sourcing & Preservation
Specimens are responsibly sourced from marine environments and preserved in formalin to maintain anatomical integrity for long-term educational use and repeated classroom handling.
Note: This is a preserved marine invertebrate specimen. Natural variations in size, color, and appearance should be expected. For bulk or institutional orders, please contact info@gulfofme.com.
