The horse and mouse are endotherms among them rat will have high mass-specific metabolic rate.

The shark and fish are endotherms among them fish will have high mass-specific metabolic rate.

Explanation:

The endotherm (heat requires in them to maintain internal temperature of the body) organism have high metabolic rates to maintain homeostasis, this requires the large amount of energy. Smaller animals have the greater surface area to volume ratio, hence more heat loss and higher metabolism. In larger animals body volume increases, surface area increase is also very slow, hence less heat loss and lower Metabolic rate. Smaller animals exchange oxygen to tissues at a high rate.

Same goes with ectotherms the larger the animal the smaller is the metabolic rate. During winters their activity slows down as they cannot adjust with the temperature of the surrounding.

However metabolic rates of ectotherm and endotherm cannot be compared.

What animal has spiny armor that protects it from predators and cushions its falls from trees?
CaHeK987 [17]
The hedgehog are animals with spiny armor that protects it from predators and cushions its falls from trees. Animals have different survival mechanisms and means to protect themselves from possible predators. For example; a Camel has long eyelashes and hair-lined ears that blocks blowing sand, can close its nostrils to keep sand out. Others like Koala uses specially designed hands and feet and a thick, padded tail to hold on to tree branches for long periods of time.
