The Impacts of Temperature and Salinity on Marine Animals

Ectothermic Animals

• So called “Cold Blooded”• Body temperature dependent on environmental

heat sources (i.e. basking in sun)• Examples: Fish, Amphibians, Reptiles

Endothermic Animals

• So called “Warm Blooded”• Maintain a stable internal body temperature

(using fur, fat, feathers, or behaviors, like sweating/shivering)

• Examples: Mammals, Birds
