Why do sharks prefer warm water?
“They have to keep their body temperature elevated. We believe that these warm eddies allow white sharks to forage longer at depth, where most of the biomass in the open ocean is found. One reason that the sharks might prefer them is by diving in these warm eddies, they can spend more time in the deeper water.”
Do sharks like cold or warm water better?
Conclusion. As a group, sharks mostly prefer warm waters as it is easier for them to hunt for their prey in these regions. However, some shark species can easily adjust their body temperatures to thrive in colder waters too.

Do most shark attacks happen in 3 feet of water?
Don’t think you’re safe just because the water is shallow — shark attacks can occur in less than three feet of water. While shark activity tends to be greater a few hundred yards from shore, stay alert even if you’re in thigh-deep water.
Are sharks coming closer to shore?

Everybody can make their own personal decision, but realizing that sharks can get into water as shallow as five of six feet deep is something that people need to realize.”
Do any sharks live in cold water?
