Peppery furrow shells live burrowed deep in the bottom. In order to get fresh water and food, it sticks two siphons out of the bottom. They must be very long, sometimes as much as 25 centimeters. That's four times its own shell length. The siphons are not directly next to each other; otherwise it would drink the filtered water that it just ejected. Besides filtering the water for food, this species is also able to graze the surface, leaving behind typical 'sparkle-like' tracks on the bottom of the tidal flats. The siphons are an easy bite for all kinds of fish and birds.
