Comprehensive Mediterranean Marine Life Collection - Thematic Shell Selection - Gastropods & Bivalves (20 pieces) A charming and diverse study collection of 20 genuine marine shells, primarily sourced from the Mediterranean basin. This assembly showcases a variety of shapes, textures, and biological structures. The collection includes: -Bivalves: A fine selection of Cardiidae (Cockles) and Veneridae (Venus clams), featuring prominent radial ribbing and varying color patterns from creamy white to deep violet hues. -Arca Noae (Noah's Ark): A notable specimen (approx. 4-5 cm) showing the characteristic "ark" shape and rugged periostracum. -Gastropods: Several Cerithium (Needle whelks) with high-spired shells, alongside various Trochidae (Top shells) displaying beautiful spiral growth patterns. All shells are in their natural state. Some specimens show natural weathering and sea-worn textures, which adds to their authentic character. No artificial coatings or polishes have been applied. The items will be carefully packed to ensure safe delivery and shipped with a tracking number.
