The last region where sharks live is the Temperate region. These waters are a mix between the frigid polar and the warm tropical water temperatures. The average temperature range for these Temperate regions is around
10o-21o C
(50o-69.8o F).
What temperature do sharks prefer?

a balmy 22C

What is climate change doing to sharks?
Sharks are no exception. The impacts of climate change on marine life are expected to continue into the future, potentially resulting in:
Shifts in the distribution of fish populations
.
Changes in migratory patterns
.
Are sharks cold or warm?
Are sharks warm or
cold blooded
? Most sharks, like most fishes, are cold blooded, or ectothermic. Their body temperatures match the temperature of the water around them.
Where is sharks habitat?
Sharks and rays have adapted to living in a wide range
of aquatic habitats at various temperatures

How has climate change affected great white sharks?
The effects of climate change are taking their toll underwater and causing
deep sea predators
such as sharks to die out. A study published in the Journal of Animal Ecology suggests that if herbivores such as seacows lose their predators, the ecosystem will be damaged.
Do sharks swim in shallow water?
Great whites do not hunt by sitting on the bottom waiting for prey to swim above them, though they do swim generally
near
the bottom, cruising slowly, looking to ambush prey from below. Their hunting techniques are learned through experience, and in the Cape’s shallow waters they have adapted to attack seals laterally.

How do sharks warm up?
The
body heat generated from continuous swimming elevates the RM temperature
, which in turn, warms the surrounding white muscle and allows the shark to survive the frigid waters of the north Pacific. If a shark stops swimming, it could die from cold exposure.
Can sharks live in rivers?
Secondly, most sharks can only tolerate saltwater, or at the very minimum, brackish water, so
freshwater rivers
