Go silent, with "up" (4)

Ross

I believe the answer is:

clam

(Other definitions for clam that I've seen before include "Large marine bivalve" , "ringing noise produced by > very reticent type" , "Tightly closed shellfish" , "A silent type" , "Shellfish - secretive type" .)

I've seen this clue in The New York Times.
