Concholepas concholepas

Gastropoda is the largest and most successful class of mollusks (phylum Mollusca), containing over 35,000 living species and 15,000 fossil forms. The shell of gastropods is of one piece (called univalve) and usually coiled or spiraled as in snails, periwinkles, conches, whelks, limpets, and abalones.  Concholepas concholepas is a gastropod and lives along the coasts of Peru and Chile in South America.

The inhabitants call it ‘loco’ and collect it for eating.
