Key Differences Between Eurythermal, Stenothermal & Euryhaline Animals

BY Team Aakash Byjus

Eurythermal Organisms

Eurythermal organisms are organisms that can bear wide ranges of temperatures.

Organisms under the adult stage or larva stage can also tolerate various temperature changes.

These organisms are endotherms that maintain constant body temperature.

These are also known as warm-blooded animals. They can regulate body temperature by generating heat inside their body.

Eurythermal organisms are of two types. These include cold eurythermal and stenothermal organisms.

Cold eurythermal organisms can survive in extremely cold conditions also. Example: Dog, Cat, human.

Stenothermal Organisms

Stenothermal organisms are organisms that can tolerate a narrow range of temperatures.

These are endotherms and warm-blooded animals. These organisms are capable of generating heat inside their bodies.

These organisms have a special protein in their bodies to regulate the temperature. Example: Reptiles, salmon, insects.

Organisms are of two types based on salinity regulation. These include euryhaline and stenohaline organisms.

Euryhaline organisms can tolerate a wide range of salinity. Examples: Green crabs.

Euryhaline organisms have special mechanisms to regulate salinity.

These organisms reduce the net flux of water into or out of their bodies from diffusion.

They maintain internal salinity within their bodies at a level equal to the osmolarity of the surrounding medium.

These organisms regulate salinity by taking in or sending out water and electrolytes.
