ARCTIC Does the Clam Mya truncata Regenerate Its Siphon after Predation by Walrus? An Experimental Approach

ABSTRACT. Walrus (Odobenus rosmurus) prey extensively on the bivalve Myu truncutu, removing the siphons. We performed a simple experiment whereby the siphons from 2 7 M. huncata were removed, 33 controls were left intact, and the clams left on the sea bottom for a year. All the damaged Myu died; all...
