Truncata Spider Conch Seashells
Lambis Truncata
AKA: Giant spider conch. Truncata Spider Conchs are the largest and heaviest of the spider seashells. The outer lip features several finger-like digitations which are longer on female shells than they are on the males. The extra large size and odd shape create a very impressive display to behold. They're common on rubble and coarse sand in the warm tropical waters of the Indo-Pacific.
