No. Sharks are ectothermic, which is commonly referred to as 'cold-blooded'. Sharks are fish, and all fish are ectothermic, as are reptiles and amphibians. Their body temperature is dependent on external environmental conditions.
A goldfish is ectothermic.
Endothermic sharks, such as the mako and blue-fin shark, have a special organ which allows them to retain regenerated heat. A ten degree rise in their body temperature can result in an increase of speed and strength. They have a special bundle of arteries and veins which help in preventing heat loss.
Yes. A dolphin is endothermic, able to maintain its own body temperature. It is a mammal, and mammals and birds are endothermic. The term 'endothermic' is the biological term for an animal that is warm-blooded.
Turtles are exothermic. All reptiles are, and most fish too. (Some larger sharks are endothermic.) Mammals and birds are all endothermic.
Most sharks are ectothermic, but some (namely the Great White) can produce their own body heat. They do this by using the heat produced by burning energy from pumping their blood. As blood is pumped to the body, the blood moving back to the heart gives off its heat which is picked up by the cold blood. In this way, some sharks can be warmblooded, but most are ectothermic.
endothermic
Its endothermic :)
Freezing is exothermic, as the substance that is freezing loses energy to its surroundings.
Yes. A wolf is endothermic, able to maintain its own body temperature. It is a mammal, and mammals and birds are endothermic. The term 'endothermic' is the biological term for an animal that is warm-blooded.
Endothermic
It is endothermic. Endothermic is to gain heat and Exothermic is to lose heat.
All ENDOthermic reactions are of course ENDOthermic by themselves, aren't they?
