The scars on a Sperm whale are caused by the suckers of giant squid. Each sucker has a sharp serrated ring of chitin which helps the squid attach itself to its prey. They will battle to survive the jaws of the sperm whale, by attaching themselves to the sperm whales skin, which causes circular tears and scratches.
Gray whales are baleen whales. The Sperm whale is the only really big toothed whale.
The sperm whale is a toothed whale. The sperm whale could be the biggest animal in in existence that has teeth. It has big teeth (in it's lower jaw) to catch and eat large prey, such as the giant squid. Baleen is not a tooth, but, is a flexible plate, and baleen whales have many of them in the front of the mouths. Baleen whales, such as the blue whale, eat very small animals such as plankton by taking large amounts of water into their mouths. The whales then strain the water through their baleen, which traps the plankton inside, which are then swallowed. Whalers who caught sperm whales in the past, would sometimes take the large teeth and make drawings on them.
