Deep oceanic WATER is never colder than 32 Fahrenheit- at extreme depths. the high pressure induced by the depths prevents freezing. Sharks are as rugged as Carborundum, their skin feels like it. They have no trouble adapting. Sharks are cold-water fish anyhow.

Why are there no sharks in Lake Ontario?
Sharks have evolved to survive in salt water and are usually found in the ocean. Lake Ontario is fresh water. And Niagara Falls prevents them from traveling to the lake. Actually, Niagara Falls is on the Niagara River which empties into Ontario from the west. The lake connects to the ocean via the St. Lawrence River on the east, so sharks could, in theory, enter Lake Ontario. They could get into the other lakes through the Welland Canal between Erie and Ontario or through canals from the Mississippi, but none have been reported much further north then St. Louis which is 1000 miles downriver. The lakes are young, formed when glaciers retreated about 12,000 years ago, which would limit shark adaptation to their environment. Given the cold temperature of the Great Lakes they wouldn't be a good habitat for sharks. The bull shark, which can tolerate fresh water, is primarily tropical. Bull sharks have been recorded as far north as Massachusetts which is roughly 200 miles east of Lake Ontario but would have to enter the lakes through the Gulf Of St. Lawrence which is very cold year-round. I would be very surprised if a bull shark or any other species would survive very long in Lake Ontario or the Great Lakes. One or two pups might get into the water from the ballast water of ocean-going vessels (although they now have to purge before entering the lakes) or be released from a home aquarium, but they wouldn't last very long.

What are some similarities between sharks and dolphins?
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.

Most whale sharks, live in the deep ocean and feed on plankton. They live in the open ocean, so the large sharks will not be stranded in the shallows, and to avoid predators that live near the shore.
