What are the similarities between the sharks and the dolphins?
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

In the movie Finding Nemo what kind of symbiotic relationship does dory have with the sharks?
In "Finding Nemo," Dory does not have a symbiotic relationship with the sharks; rather, she encounters them as potential threats. The sharks, particularly Bruce, are portrayed as trying to adopt a "fish are friends, not food" philosophy, attempting to overcome their predatory nature. While Dory engages with them, the relationship is more one of avoidance and tension rather than mutual benefit. Overall, the interactions highlight the contrast between predator and prey rather than a true symbiotic bond.
