Watching the World Wolves Go Fishing For years it was thought that a wolf’s diet consisted exclusively of land animals such as deer. According to Canada’s Vancouver Sun, however, wolves dwelling in the rain forests along the central coast of British Columbia have been observed eating mussels, clams, barnacles, and even salmon ​ — “as many as 20 in one hour. ” They stealthily watch a fish, and then “in one swift and lethal move, they plant all four feet firmly in the water and strike, ” making a catch about 4 times out of 10.
