This preserved sea urchin is a formalin-preserved marine invertebrate specimen commonly used in classrooms and laboratories to study echinoderm anatomy and marine biology. Its rigid test and distinctive spines make it an excellent model for invertebrate anatomy and comparative biology instruction.
Specimen Details
Common name: Sea urchin
Scientific name: Strongylocentrotus droebachiensis
Size: 2–3 inches
Preservation method: Formalin-preserved
Habitat: Shallow coastal and subtidal 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 anatomical features such as the test, spines, and Aristotle’s lantern.
Anatomical Features
Rigid calcareous test
Prominent spines characteristic of sea urchins
Internal feeding structure (Aristotle’s lantern)
Suitable for invertebrate anatomy and marine biology study
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.
