Many collectors consider the harps to be the most beautiful of all shells. With their stately shape, complex sculpturing, intricate patters, coordinated color scheme and mid size, they live up to the claim.
The Harps are a small family that inhabit tropical waters, with the majority found in Philippine and Pacific waters. Harpa harpa, Linnaeus 1758, commonly called the Noble Harp is the namesake species and our shell of the month. We have two specimens, similar in size and although at first glance they appear nearly identical a close inspection will reveal many differences. Harpa harpa has about a dozen ribs with spines on the posterior end. Between the spines are fine groves with rows of chevron patterns. Distinguishing marks from the other harps are the groups of 2 or 3 fine black lines hat cross the ribs and the three brown blotches on the base.
Harps are carniverous and feed on small crabs and shrimp. They burrow in the sand and live in moderate depths.
These specimens, are both in gem condition with mature lips. They are from the collection of Richard Kent.
