Do sharks prefer warm or cold water?
Sharks are no different. Each species has a temperature range that makes them most comfortable, whether that’s the warm waters of the tropics, the cold waters around the North and South Poles, or anywhere in between. Unfortunately, this could create future challenges for sharks since ocean temperatures are on the rise.
What temperature water attracts sharks?

What do sharks hate?
Natural repellents
