Classify Rohu, Scoliodon, flying lizard, king kobra, frog, salamander, ostrich, pigeon, bat, crocodile and whale into the cold blooded/warm blooded animals. Cold blooded creatures take on the temperature of their surroundings. They are hot when their environment is hot and cold when their environment is cold. In hot environments, cold-blooded animals can have blood that is much warmer than warm-blooded animals. Cold-blooded animals are much more active in warm environments and are very sluggish in cold environments. This is because their muscle activity depends on chemical reactions which run quickly when it is hot and slowly when it is cold. A cold-blooded animal can convert much more of its food into body mass compared with a warm-blooded animal. e.g., Rohu, flying lizard. Warm blooded Warm-blooded creatures, like mammals and birds, try to keep their bodies at a constant temperature. They do this by generating their own heat when they are in a cooler environment, and by cooling themselves when they are in a hotter environment. To generate heat, warm-blooded animals convert the food that they eat into energy. Their have to eat a lot of food, compared with cold-blooded animals, to maintain a constant body temperature. Only a small of the food that a warm-blood animal eats is converted into body mass. The rest is used to fuel a constant body temperature. e.g., Scoliodon, ostrich, pigeon, bat and whale.
