Jellyfish do not actively control their body temperature, their body temperature is that of the water surrounding them. However, they can swim and could move to, or keep themselves in, a body of water where the temperature suites their needs.
yes they can control their body temperature
Ecothermic because jellyfish aren't warm blooded
Control of body temperature is important for maintaining homeostasis.
Water supports a jellyfish's body.
Animals that do not control their body temperature but rather let the environmental temperature control it are called cold-blooded or the technical term is ectotherm.
Homeostasis.
The sweat glands control body temperature.
by swimmingThe turtle, a cold blooded animal, does not control its body temperature, It takes on the temperature of its surrounding environment.
All animals use the environment to control their temperature
Their body temperature is controlled by their environment. Mammals are endothermic. Meaning that they control their own body temperature.
Because box jellyfish, as with all other cnidarians, do not have blood, or a circulatory system, they can not be considered "cold-blooded." However, they are ectotherms whose body temperatures are equal to the temperature of the environment.
The testicles are outside of the body for temperature control. The sperm develop best when the temperature is lower than the body temperature. If the testicles were kept at body temperature, the sperm would not develop correctly. The body has an ingenious temperature control mechanism, as well, for the testicles. If it is too hot for them, they descend and hang further away from the body. If it is too cold for them, they come up closer to the body!
