What is a cartilage Fish blood temperature?

Cartilaginous fish, such as sharks and rays, are classified as ectothermic, meaning their body temperature is largely influenced by the surrounding water temperature. Their blood typically has a temperature close to that of the water they inhabit, which can vary widely depending on the environment. Unlike bony fish, cartilaginous fish have a unique osmotic regulation system that helps them maintain some internal stability despite external temperature fluctuations.
