Elasmobranchii is a subclass that includes the sharks and the rays and skates. Members of the elasmobranchii have no swim bladders, five to seven pairs of gill clefts opening individually to the exterior, rigid dorsal fins, and small placoid scales.
Wolf Prey Animals and food diet. Wolves predominately prey on hoofed animals including Deer, moose, Bison, Elk, and caribou. Because wolves usually hunt for large animals, (although wolves are opportunistic and will eat smaller prey) they work together to catch their prey. Wolves will eat a healthy, strong animal if they can catch it.
Historically, salmon has been under-reported as a food source for wolves, in part because it doesnât show up in wolf scat the way evidence of deer or beaver does. The bones, fur and hair in wolf droppings offer good clues to the predatorsâ diet, but wolves can completely digest salmon bones.
