Welcome to the Terrestrial Invertebrates category. Keeping arthropods requires absolute dedication to microclimate management. This section covers the precise husbandry of tarantulas, scorpions, isopods, and praying mantises. You cannot keep a Theraphosa blondi in a dry plastic box. We detail the exact humidity requirements and substrate depths needed to facilitate proper molting. A bad molt is almost always a fatal husbandry error. We explain the mechanics of burrowing behaviors and the necessity of appropriate hides. You will learn about the dangers of urticating hairs and the varying venom toxicities of species like Pandinus imperator. We break down the dietary needs of these predatory and scavenging organisms. Gut-loading your feeder insects is mandatory. We cover secure enclosure designs to prevent escapes. Invertebrates can squeeze through impossibly small gaps. Stop handling your tarantulas. They are fragile display animals. A short fall from your hand will rupture their abdomen. Read our detailed care sheets. Master your environmental gradients. Provide the exact biological parameters these fascinating ancient creatures demand to survive in captivity.
