Abstract
Reviews reports of walrus feeding on seal or whale carrion, or killing them for food. Normally, bottom feeders (benthic invertebrates) in shallow, continental waters, walrus eat mammals when/where invertebrates are unobtainable. The (rare) rogue walrus, habitually carnivorous, has a distinctive external appearance. Some catch data are given with estimates of the carnivores, also those with Trichinella infection. The possibility is aired that such animals like the polar bear, have a high vitamin A content in their liver, or may be a source of trichinosis transmissible to man. Comments by T. H. Manning in Arctic, Mar. 1961, p. 76-77.
