Abra is a genus of saltwater clams, marine bivalve mollusks in the family Semelidae. Members of this genus are mostly under 1.5 centimeters long, and have thin shells which are usually white. These bivalves normally live under the surface of sandy and muddy sediments, in the neritic zone.[1]
They are considered an important food source for flat fish.[2]

Streptaxoidea is a superfamily of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the suborder Achatinina of the order Stylommatophora.
Taxonomy
2005 taxonomy
There have been recognized the only family Streptaxidae within Streptaxoidea in the taxonomy of Bouchet & Rocroi (2005).[2]
2010 taxonomy
Sutcharit et al. (2010)[1] have established a new family Diapheridae within Streptaxoidea as follows:
family Streptaxidae Gray, 1860
family Diapheridae Panha & Naggs, 2010[1]
Rowson et al. (2011)[3] have confirmed monophyly of Streptaxidae and Diapheridae as its sister group.[3]
