Tarantulas
The tarantula is an invertebrate that, like all arthropods, depends on an exoskeleton for muscular support. Typically, trapdoor spiders, funnel-web spiders, purse-web spiders, and occasionally even members of the Lycosidae family of spiders are mistaken for tarantulas. A tarantula can be recognized in a variety of ways. First, the hairs: most tarantulas in the Americas have urticating hairs, while some, like those in the Hemirrhagus genus, do not. Compared to the majority of other spiders, the hairs are typically more obvious. Another factor is size; tarantulas tend to be larger, but this is not a foolproof method either. Additionally, they don't hunt with their webs; instead, they employ them as tripwires or building materials.
Although they both belong to the same class, the Arachnids, scorpions and tarantulas do not get along. The two are natural adversaries, with tarantulas typically winning battles. Tarantulas are bigger than scorpions, have enormous, poisonous fangs, and have hairs all over their body to improve their sense of smell. Additionally, they can easily combat scorpions due to their strength and speed.
