Scientists said that the metabolic costs in maintaining their weapons are essential in shaping the evolution of diverse structures.ĪLSO READ: Humans' Defenseless Nature: Still, Why Don't Wild Animals Attack Us More? Inert Components Helps Animals Cheat Meanwhile, the largest deer develop large antlers compared to smaller deer, similar to how large elephants develop larger tasks than the smaller ones. Scientists discovered that the resting metabolic rate of one-legged bugs is down by almost a quarter in males while only about 7.9% in females. When scientists calculated the cost of maintaining the large hind legs of lead-footed bugs, they found that males invest more in their weapons while large males expend relatively less energy compared to smaller ones. According to the University of Florida News, wild animals spend 30% to 40% of their total energy budget while at rest. However, they are metabolically costly to maintain. ![]() Large, Chunky Animal Weapons Are Costly to MaintainĪntlers, tusks, and claws are examples of animal weapons that are often large, chunky, and heavy. Some arthropods develop giant exoskeletons to support a large bulk because the new soft tissue might collapse following a molt. The exoskeletons provide a large surface area for attachment of the muscles, support, movement, and protection. ![]() It is somewhat analogous to the armor encasing a medieval knight.Īccording to Britannica, most arthropods move using their segetal appendages and their exoskeletons and muscles attached to the inside of their skeleton to act as a lever system. ![]() Cheaters in Animal Kingdom Win: Large, Exaggerated Appendages Deceive Opponents During A Fight Muscles, Appendages, Locomotions of ArthropodsĮxoskeletons of arthropods are divided into plates to cover their body and appendages.
