Dead Sea Seashells, Segment D, part 5 of 6

 

These shells are those of “keyhole” limpets. Like true limpets, the “keyhole” limpet has a conical shell. However, the creatures that produce these shells are a type of sea snails, and not closely related to limpets.The hole at the top allows the creature to expel water and waste. Typically, such snails are bottom feeders, feeding on vegetable or other organic waster material.
