There’s a reason why movies like Jaws tell a story about ruthless, blood-thirsty monsters of the ocean. Sharks are living dinosaurs, and technically, they were here before dinosaurs roamed the earth. These fearsome creatures get a bad rap due to their incredible hunting abilities and fearsome appearance.

Great white sharks are the most aggressive and dangerous sharks in the world. And due to their appearance, salmon sharks often get mistaken for great whites. But what sets them apart from each other? Let’s analyze their differences and similarities: salmon shark vs. great white shark. Plus, find out who would win in a fight.

They key difference between salmon sharks and great whites is that salmon sharks are much smaller than great whites, have a different diet, and tend to be more social than the solitary white shark. Let’s dive into the differences between salmon sharks and great whites. 

Size and Appearance Differences

The salmon shark is a strong swimmer with a broad tail that has a rare double keel and a short ridge that runs along the lower part of the tail. Their skin is typically dark grey with random white markings, and their underbellies are white with darker splotches. 

This species can grow to 10 feet long but average between 6.5 and 8 feet. Larger salmon sharks can weigh more than 660 pounds, but most hover between 400 and 500 pounds. Other characteristics include round dark eyes, long gill slits, short snouts (cone-shaped), and large teeth. 

Great whites are the largest predatory fish on the planet and excellent hunters. They have pointed conical snouts, large finds, and a crescent-shaped tail. Their bodies look like blunt torpedos, and their jaws are filled with sharp, serrated teeth. 

Great whites have contrasting colors of dark blue, grey, or brown with a white underbelly. A fully grown white shark doesn’t typically exceed 21 feet in length, and most weigh between 1,500 and 4,000 pounds. However, the largest can weigh over 5,000 pounds

Salmon Shark Behavior vs Great White Sharks

Salmon sharks swim in the coastal and oceanic environments of the subarctic and North Pacific Oceans. They prefer temperatures between 36 and 75 degrees Fahrenheit and lurk from the surface to 500 feet. Salmon sharks are endothermic, meaning they regulate their body temperature 20 degrees above the ambient water temperature. 

This species is semi-social and will hunt in groups or by themselves. Their groups comprise of the same gender and same average size. They can be aggressive and are potentially dangerous to humans, but they’ve never been identified in an attack. 

White sharks are globally distributed, but you can most often find them in South Africa, Australia, North Atlantic, and Northeastern Pacific. These sharks thrive in a water temperature between 54 and 75 degrees Fahrenheit and can dive to a maximum depth of 775 feet. This fierce predator is also endothermic, allowing them to remain swift and agile even in cold water. 

Researchers have always seen great whites as largely solitary animals, but new evidence suggests that they are more sociable than previously thought. They will occasionally group into pairs and travel together for long distances, working to catch prey. More frequently, though, they are loners until mating season. Great whites are one of the most aggressive sharks in the ocean and have attacked more than 300 humans; almost 60 were fatal. 

What Great White Sharks Eat vs Salmon Sharks

The main diet of a salmon shark consists of salmon (obviously), sablefish, trout, squid, herring, pollock, sardines, and sculpins. While those animals are its food of choice, it will settle for what is in abundance. 

Their unique features like broad tails propel them through the water, making them exceptionally fast. They have tiny pores on their snouts that gather signals and help them identify movement nearby, and they have a binocular vision to locate food quickly. And finally, its sharp teeth pull bite-size pieces off of its kill. 

Great whites are one of the primary predators of marine mammals and eat seals, sea lions, sea turtles, porpoises, dolphins, and small whales. This species is still opportunistic but rarely indulges outside their favorites. 

These apex predators are highly skilled, athletic hunters who use their torpedo-like bodies to leap entirely out of the water. They lurk below their prey, waiting for the perfect opportunity to strike. Due to these refined hunting skills, they rarely miss. 

Great whites have strong muscles, good eyesight, and a keen sense of smell. Their coloring also allows them to blend in with their environment. The bite force of a great white is more than 18,000 newtons (20 times stronger than a human’s); its bite easily breaks bones and tears flesh.

While salmon sharks may be mistaken for great whites; they are much smaller. These two shark species differ from each other in many ways. Salmon sharks are smaller, more sociable, less aggressive, and feed mainly on small fish. Great whites are enormous, solitary, super aggressive, and prefer marine mammals. 

As for would win in a fight, that title goes to the great white shark, one of the most fearsome creatures in the deep blue sea.
