Whales are mammals and sharks are fish. When whales give birth to young ones, sharks lay eggs. Unlike the young sharks, young whales are fed milk. The whales raise their young ones whereas sharks do not.Whales have bones whereas the sharks have no bones.
The whale shark (Rhincodon typus) is a slow-moving filter feeding shark and the largest known extant fish species. The largest confirmed individual had a length of 12.65 m (41.50 ft) and a weight of approximately 21.5 metric tons (47,000 lb), and unconfirmed reports of considerably larger whale sharks exist. Whale sharks have a mouth that can be 1.5 m (4.9 ft) wide, containing 300 to 350 rows of tiny teeth and 10 filter pads which it uses to filter feed. Whale sharks have five large pairs of gills. The head is wide and flat with two small eyes at the front. 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, 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 Although both animals live and thrive in the ocean and there is a species of shark that is called the whale shark the whale species is very different from sharks. In fact sharks are actually considered a type of fish while whales, dolphins and porpoises are marine mammals. Another major difference between whales and sharks is how the two species give birth. Whales give birth the same way that humans and other mammals do (through a pregnancy period or gestation term) while sharks and fish lay eggs. Whales are much larger than sharks. The blue whale is the largest of all the mammals on Earth. When a whale weighs more than 100 tons, the shark weighs about 2,000 kg. Sharks hunt for their food. Whales do not have this hunting tendency. Plankton and krill are the food of whales. Whale vs Shark. Whales are mammals and sharks are fish. When whales give birth to young ones, sharks lay eggs. Unlike the young sharks, young whales are fed milk. The whales raise their young ones whereas sharks do not. Whales have bones whereas the sharks have no bones but only cartilage Sharks (fish) vs whales. In regards to the differences between sharks (which are fish) and whales (which are marine mammals) there are a number of physiological differences among the two distinct species. Whales are marine mammals and belong to the cetacean family which is made up of all species of whale, dolphin and porpoise. A whale shark is a shark, it is not a whale despite having the word “whale” in its name. In fact the whale shark is the largest fish (or shark for that matter) in the world. 3) Whale … s sharks have the same cartilaginous skeleton structure as other sharks Tthe reason its called WHALE shark is because it is the largest of all the sharks, and as whales are the currently biggest mammals on the earth it only seems appropriate. The only thing it got in common with whales is its  size.  A Whale Shark is a fish and a member of the shark family. It is  called a Whale Shark because the grow to very large size. The name whale shark comes from the fish's size, being as large as some species of whales and also that it is a filter feeder like baleen whales. Whale sharks have a mouth that can be 1.5 m (4.9 ft) wide, containing 300 to 350 rows of tiny teeth and 10 filter pads which it uses to filter feed. Whale sharks have five large pairs of gills. The head is wide and flat with two small eyes at the front. They could be either predators (e.g. Killer whale) or filter feeders. Whales are long lived mammals with a lifespan of 70 – 100 years. Differences between Shark and Whale. • Sharks are fish and cold-blooded, whereas whales are warm-blooded mammals. • Sharks have a cartilaginous skeleton, but it is a bony skeleton in whales. • Whales are generally larger in body size than sharks. • Whales have lungs sharks have gills for breathing. • The body of the whale is covered with hair but shark has dermal denticles covering the skin.  Sharks have no such migrating tendency. Whales are also endangered whereas sharks are not. Summary: 1.When a whale weighs more than 100 tons, the shark weighs about 2,000 kg. 2.Whales give birth to young ones; sharks lay eggs. 3.Plankton and krill are the food of whales. However, toothed whales feed on squid and small fish. Whale vs Shark. Whales are mammals and sharks are fish. When whales give birth to young ones, sharks lay eggs. Unlike the young sharks, young whales are fed milk. The whales raise their young ones whereas sharks do not. Whales have bones whereas the sharks have no bones but only cartilage
