An arachnologist studies what are arguably the most hideous and terrifying creatures on earth. No, we’re not talking about the cast of Duck Dynasty, we’re talking about spiders. Fear of arachnids frequently ranks among the most common phobias found in people.

The good news is that arachnologists aren’t limited to the study of spiders; they also study scorpions, ticks, and mites.
