Deep sea creatures tend to be much larger than those living in shallow waters due to factors like food scarcity and cold temperatures. Kleiber’s Law explains that larger animals have a more efficient metabolism, allowing some giants to consume very little food. Additionally, Bergman’s Rule suggests that animals in colder environments will grow bigger compared […]
