whale sharks have distinctive white spots in their heads, and blue whale are considerably bigger then. And I think blue sharks are more aggresive than whale sharks . _ The blue whale is the largest mammal on Earth. The underside of its flippers are almost white, while the rest of its body is blue grey. The average blue whale is 75 to 80 feet long and weigh up to 110 tonnes. Females are larger and can weigh up to 150 tonnes. The whale shark can be grey, blue or brown with white dots and light vertical stripes over its entire body. Their mouths are located in a terminal postition and can be opened wide to filter water for small fish, squid, crustaceans, and other plankton organisms. The whale shark is related to the nurse shark, and therefore has relatively small eyes, spiracles and barbels. ------- A: The Whale Shark (Rhincondon typus), the largest of the sharks, is a member of class chondrichthyes; cartilagenous fish. In most sharks, the only actual "bones" are the denticles on the shark's skin and, in toothed sharks (not the WHale Shark), the teeth. The endoskeleton is cartilege. Sharks aren't warm blooded. The Whale Shark, like the Blue Whale, are both filter feeders. Blue Whales (Balaenoptera musculus), on the other hand are class mammalia--- they're mammals, as we are. They are warm blooded, have hair, bear and nurse their young alive. As with all Mysticetes (the sub class), they are filter feeders. So, in summary, whales and shark, including the Whale Shark and Blue Whale are taxonomically radically different, starting and Class, and only come together under phylum which, for both, is Chordata. A: A whale and a shark can not come from the same family but they can be similar.they both eat meat, they both stay with there family, and they both hunt for food.
