About
Overview
The major harp (Harpa major) is a large, predatory marine gastropod known for its striking, elegant shell patterns. Often sought after by collectors, this sea snail is a notable member of the family Harpidae, which is characterized by shells that resemble the strings of a harp.
Distribution & habitat
This species is widely distributed across the tropical and subtropical waters of the Indo-Pacific, ranging from East Africa and the Indian Ocean to Japan, Hawaii, and French Polynesia. It typically inhabits sandy seabeds, often frequenting areas with rubble or seagrass. While it can be found in shallow waters, it is also observed at moderate depths, where it frequently buries itself partially in the sand.
Appearance
The shell of the major harp is ovate and glossy, featuring prominent, raised longitudinal ribs that run vertically along its surface, creating a pattern reminiscent of harp strings. These ribs are often marked with thin white lines against a creamy white or pale background, interspersed with dark brown or reddish-brown bands. A key identifying feature is the heavily calloused spire and a distinct dark brown coloration on the columella. The snail itself possesses a very large foot relative to its shell size, a long siphon, and a large mouth aperture.
Biology & behavior
Generally solitary, the major harp is a predatory snail that spends much of its time partially buried in the substrate. It is an active hunter that feeds primarily on small crabs. When threatened or moving across the seafloor, the animal can extend its large, muscular foot, which is often cream-colored with brown spots.
