The valves are concentrically sculpted and more sharply triangular in cross-section than a similar Tellin, Eurytellina rubescens.

Another difference between these two closely related species is that the pallial sinus does not touch the anterior adductor scar in E. simulans, while it does in E.

[3] The animal was originally described to science by naturalist Charles Baker Adams, a professor of zoology at Amherst College.

He collected furiously upon arrival, and on January 3, 1851, shipped eight crates back to Massachusetts.

[3] Like other Tellins, they are filter feeders, extending their siphons up through the sand in order to breathe, strain nutrients from the water, spawn, and to excrete waste products.
