Adaptive traits for survival are physical or behavioral characteristics that increase an organism's chances of escaping predation, intaking nutrition, and avoiding (or reducing the damage done by) injury. Camouflage is a ubiquitous adaptive trait used by insects, amphibians, and mammals. In the presence of predators, the insect species phasmatodea changes color to blend in with plant surroundings, reducing its chances of being noticed and attacked. Many species of lizard, frog, and snake also use this form of camouflage. The natural color of the polar bear, and the darkened fur of leopards' spots, are examples of mammalian camouflage.
Adaptive traits for reproduction help organisms produce viable offspring. Some adaptive traits for reproduction actually increase an organism's vulnerability to predation; so successful reproduction can involve an evolutionary trade-off or risk of some sort. One classic example is the male peacock's brightly plumed feathers. The vivid, extravagant tail is heavy and cumbersome. Plus, it makes him more easily spotted by predators. However, the colored feathers serve to attract females. They help the male peacock to produce viable offspring. Other examples of adaptive traits for reproduction include: birds' mating songs, and salmons' end-of-life return to the stream where they were spawned.
Arthropods have an outer body covering called and exoskeleton made of a special material called chitin. This material is hard and thick so it protects it from predators. It also helps the arthropods in the desert not to dry out. The exoskeleton also gives it support and connects joints and muscles inside the body. In other arthropods like shrimp, the exoskeleton works with the muscles to give it a locomotive force.
Arthropods have special mouth parts. A mosquito (arthropod) has a special mouth which allows it to break through human skin and suck our blood. Other arthropods use their mouth for many different things like taking down prey and more.
Arthropods have jointed legs which help them move fast because their legs are flexible, or jointed, so they can get away from prey or catch prey. They have compound eyes. Instead of having one lens in each eye, arthropods have several lenses in each eye which give them a very wide angle of vision. They can pretty much see all the way behind them. Although they have this great vision they can’t see far distances. Their compound eyes actually help them detect movement. This helps them because they can be aware of prey and escape.
Arthropods have segmented bodies which help them curl up into small spaces and move faster. This is helpful because when they are getting chased by prey the arthropods can crawl into small spaces that their predators can’t reach. Also, the segments help their body to move more smoothly.
