Phylum: Mollusca, Class: Bivalvia, Order: Pectinida, Family: Pectinidae, Genus: Nodipecten, Species: Nodipecten subnodosus · Pectinidae (Scallop family) · Bivalve (two-shelled), whole shell, fan shape with prominent radial ribs
Species
Nodipecten subnodosus
Shell Type
Bivalve (two-shelled), whole shell, fan shape with prominent radial ribs
Family
Pectinidae (Scallop family)
Size
Approximately 4 to 5 inches in width, which is typical for a medium-sized adult specimen of this species.
Color & Pattern
The natural shell has been heavily altered by human intervention, featuring a vibrant gloss-red base coat hand-painted with meticulous rows of stark black and white polka dots. The umbo region is black with white dots, mimicking a whimsical ladybug motif.
Rarity
Common in its natural state, though this specific hand-painted decorative variation is a unique craft item rather than a standard natural specimen.
Habitat
Found on sandy or gravelly bottoms in shallow subtidal waters, typically ranging from 5 to 40 meters deep, attached by byssus threads when young or living free on the seafloor as adults.
Geographic Range
Naturally occurs in the Eastern Pacific Ocean, ranging from the Gulf of California (Sea of Cortez) down to Peru.
Description
A sturdy, heavy bivalve shell featuring a classic fan shape with pronounced radial ribs and distinct rectangular auricles (ears) at the hinge line. The surface has been transformed into a decorative craft piece, coated in glossy bright red paint and meticulously dotted with polka-dot patterns in black and white.
Key Features
Heavy, robust fan-shaped bivalve with symmetrical ears, distinctive radial ribs, and a straight hinge line, though obscured here by artisan paintwork.
Collector Value
Low value for strict conchologists and scientific shell collectors due to the artificial painting, but holds moderate appeal as coastal home decor or artisan crafts, typically valued around $10 to $25.
Condition Notes
The underlying shell is intact and structurally sound, but the natural surface is completely covered by thick synthetic paint and a high-gloss finish. Collectibility grade is tailored for decorative folk art rather than natural conchology.
Interesting Facts
While living, lion's paw scallops can swim short distances by rapidly clapping their valves together to expel water. They possess numerous tiny blue eyes along their mantle edge that can detect light and shadow.
Ecological Role
Scallops are important filter feeders, helping to maintain water clarity and quality in marine ecosystems. They serve as prey for various marine predators including sea stars, octopuses, and large fish.
Similar Species
Lion's Paw Scallop (Nodipecten nodosus) from the Atlantic, which features prominent knobs on the ribs. The painted decoration makes species-level differentiation challenging without viewing the interior hinge.
Beach Finding Tips
Natural specimens of Nodipecten subnodosus are typically obtained by scuba divers in the Gulf of California rather than beachcombing, as they inhabit deeper subtidal waters.
