👉 Xenodermatids are a group of organisms that include insects, spiders, crustaceans, and some mollusks. They are characterized by their thick, waxy skin, which is made up of specialized cells called exoskeletons that protect the body from external threats and aids in locomotion. These animals have a wide range of adaptations for survival in their environments, including large eyes, long tentacles for feeding, and strong legs that help them navigate through their habitats.
