One advantage an exoskeleton provides is a strong outer layer that acts as armor against predators and environmental hazards. It also serves as a protective water barrier, and it imparts advantages related to structure and mobility.Know More
Like endoskeletons, exoskeletons provide structure and support to an animal's body. However, exoskeletons encase all of an animal's living tissues, protecting them from damage and attack. Muscles used for locomotion attach directly to the exoskeleton, giving the animal better leverage for rapid movement.
One of the most important functions of an exoskeleton is to prevent land-dwelling species from drying out. This is crucial because of the vital role played by water in physiological processes. On the other hand, an exoskeleton protects ocean-dwelling animals from being affected by small changes in the saltiness of water in their environment.
While some exoskeletons are dense, such as the hard shells of clams, the exoskeletons of insects are lightweight, making it possible for them to fly. Being nonliving, an exoskeleton does not grow with an animal. Therefore, it must be periodically shed in a process called molting. A new exoskeleton is then formed from epidermal secretions. This process consumes metabolic resources, and the animal is vulnerable until the new exoskeleton hardens.Learn more about Zoology
One example of adaptation exhibited by oysters is their hard shell, which protects the mollusks from predators. Additionally, as inhabitants of the harsh intertidal zone, where the temperature and water levels fluctuate, oysters have evolved physiological mechanisms to cope with these challenges. According to a study published in the journal “Nature,” oysters have genes that help them cope with the high stress levels caused by the constantly changing climate.Full Answer >
Butterflies use warning colors and concentrations of poison within their bodies to ward off predators. They also utilize camouflage, large eye spots, mimicry and flight to avoid being eaten.Full Answer >
Each type of frog has a different way of defending itself against predators. Some frogs use camouflage as a means of hiding from their predators.Full Answer >
All centipedes are predators, generally feeding on other invertebrates such as insects and spiders, although larger species will feed on small vertebrates such as lizards. They hunt using the legs on their first body segment, which are modified into poisonous fangs. There are a large number of centipede species, which are generally small, but some species reach up to 10 inches in length.Full Answer >
