Razor Clam vs Quahog
A razor clam and a quahog both burrow into sandy or muddy Atlantic coastal habitat and filter the same water for a living, but one survives by outrunning trouble underground in seconds while the other survives by simply outlasting nearly everything else around it, sometimes for centuries.

| Primary defence | Speed, vibration-triggered retreat | Thick, durable shell |
| Cultural significance | None notable | Source of wampum |
| Diet | Filter feeder, plankton | Filter feeder, plankton |
| Habitat | Sandy intertidal and subtidal zones | Sandy or muddy shallow coastal waters |
| Conservation status | Least Concern | Least Concern |
Razor Clam vs Quahog: common questions
Which is harder to catch, a razor clam or a quahog?
The razor clam is considerably harder to catch, since it can dig straight down into wet sand within seconds of being exposed and can detect vibrations that trigger an even faster retreat, while the quahog burrows into sandy or muddy substrate and then stays largely stationary, relying on its thick shell for protection rather than a rapid escape.
Why is the quahog connected to wampum?
Indigenous peoples of the Atlantic coast historically crafted the purple and white portions of the quahog's shell into wampum, used as a form of currency and for ceremonial and diplomatic purposes, a cultural role the plainer-shelled razor clam never held.
How long can a quahog live compared to a razor clam?
A quahog can live for an extraordinarily long time, with some individuals documented living for centuries, far outlasting the razor clam, whose defining trait is its extremely fast digging speed rather than any comparable claim to exceptional longevity.
