When checking for freshness in mollusks such as clams or oysters, a key indicator of freshness is when the partially open shells snap shut when lightly tapped. What mollusks are the exception to this rule?

Razor clams
Hamma-Hamma oysters
Cherrystone clams
Littleneck clams

Explanation

Answer: A - Razor clams are unable to close fully due to their enlarged siphons. Other examples of mollusks with enlarged siphons are geoducks and steamer clams. Most mollusks should close quickly and easily when agitated. If they do not close when tapped, it is an indication that they have died.
