Eurytellina simulans is a species of bivalve mollusc. This species was previously known as Tellina simulans. The animal was originally described to science by naturalist Charles Baker Adams, a professor of zoology at Amherst College. Adams left for an expedition to Panama in mid-November 1850. He collected furiously upon arrival and on January 3, 1851 shipped eight crates back to Massachusetts. These contained 41,830 specimens of 516 species of molluscs. He described Tellina simulans on the basis of a single valve.

Macoma nasuta, commonly known as the bent-nosed clam, is a species of bivalve found along the Pacific Ocean coast of North America. It is about 6 cm (2.4 in) long. It is often found buried in sands of 10–20 cm (3.9–7.9 in) in depth. This rounded clam has no radial ribs.

Macoma tenta, the narrowed macoma clam or elongate macoma is a species of clam, a marine bivalve mollusk (bivalvia) in the family Tellinidae and genus Macoma. Macoma tenta are one of two species of macoma clams that can be found in the Chesapeake Bay on the eastern shore of the United States in Maryland and Virginia. The macoma tenta like their cousin in the Chesapeake, the Macoma balthica or Baltic macoma clam, are small marine bivalves with thin, chalky white shells. They tend to live buried in the sandy or muddy areas of shallow water in the middle and lower Chesapeake Bay. Macoma clams are among the most abundant clams in the Chesapeake Bay. Macomas first appeared about 750,000 years ago.
