Family Myacidae is a group of bivalve mollusks commonly known as gaper clams or softshell clams. They can be found along the coastlines of North America, Europe, and Asia. Other synonyms for family Myacidae include the Myacea family, Gaping Clam family, and Soft-shelled Clam family. These clams are highly valued as seafood and are often enjoyed steamed or fried. They are also important ecological indicators of estuarine and intertidal habitat health. Gaper clams can live for up to 35 years, and their ability to filter large amounts of water makes them vital members of their ecosystem.
