The relationship between sharks and dolphins reportedly has two sides. On the one hand, they can live and hunt together peacefully. On the other hand, sometimes sharks attack lonely dolphins and sometimes dolphins in a group attack sharks. With their hard and pointed head, the dolphins ram into the smooth belly or the gills of the shark and hurt it. The shark can die because of these injuries.
Many cases of dolphins protecting humans from shark attacks have been documented, such as an attack on a surfer in northern California in August 2007. It was also documented off the coast of New Zealand in 2004. Typically, dolphins form a ring around humans who are injured. However, in spite of years of scientific study, there has been no conclusive explanation given for this behavior; as mentioned in the Journal of zoology, "The importance of interactions between sharks and cetaceans has been a subject of much conjecture, but few studies have addressed these interactions". In some cases, sharks have been seen attacking, or trying to attack dolphins. It is known that when dolphins are seen, sharks are usually nearby. As stated by ISAF: "Remember that sightings of porpoises do not indicate the absence of sharks --- both eat the same food". PIGS CAN FLY

While sharks and dolphins are certainly very different creatures, they do share some things in common. They both have dorsal fins, side fins and have a torpedo shaped figure. Additionally, they both live in water and are vertebrates.Despite the surface similarities, they are very different animals. Dolphins are warm blooded, while sharks are cold blooded. Sharks' skeletons are made out of cartilage, and dolphins' skeletons are made out of bone. Dolphins nurse their young, and sharks do not. Sharks have no hair whatsoever, while dolphins are born with hair around their noses. Additionally, sharks get oxygen through their gills underwater, while dolphins surface and get oxygen from the air through their blowholes.They both live in water (usually the ocean), they both don't sleep, they have sleek bodies for speed, dolphins, and usually sharks, both eat fish.Both have cartilagesDolphins and sharks are two ocean predators that have to compete for food and territory.They usually co-exist quite peacefully as part of a complex ocean eco-system, but occasionally they do attack and sometimes kill each other under various circumstances.Both are carnivorous (meat eaters)They both have many types, they both live in water, they both have fins, they both eat fish.
