9. Ectotherm

 This picture of fish represents animals known as ectotherms. An ectotherm is an organism that primarily gain heat through the environment as opposed to producing its own body heat. Because ectotherms cannot regulate their own body temperature, many of their behaviors during the day and night contribute to maintaining a stable internal temperature. Fish are an example of ectotherms that depend primarily on the environment for heat.
