A practical German-language guide to tarantulas, written for keepers and interested natural-history readers. The book introduces the biology and behavior of these arachnids, including their appearance, natural habitats, feeding habits, growth, and defensive behaviors. It also offers guidance for responsible captive care, with attention to enclosure setup, humidity, temperature, hiding places, feeding, handling risks, and observation. Framed within terrarium practice, it emphasizes learning the animal’s needs before acquisition and maintaining conditions that support welfare rather than treating the spider as a novelty. The volume is suited to beginners seeking a concise introduction and to experienced hobbyists who want a compact reference for husbandry questions.
