Tarantulas are diverse species that come in different sizes, colors, temperaments, and origins. One of the ways tarantulas can be separated into categories is by separating them into old and new-world tarantula groups. But what exactly is an old world or a new world tarantula? In this blog post, we embark on a journey to unravel the mysteries surrounding the group ” old world tarantulas”. From their evolutionary history to the diverse species found in Africa and Asia, join us as we delve into the unique traits and characteristics that make Old World Tarantulas truly fascinating.
Classification and Geographic Distribution
Old World Tarantulas belong to the family Theraphosidae, a group of large and often charismatic spiders. Within this family, they are further categorized into various genera, each with its unique characteristics and traits. These fascinating creatures are also not confined to a specific region; instead, they span continents, adapting to diverse environments. From the arid landscapes of Africa to the dense jungles of Southeast Asia, Old World Tarantulas have established themselves in a myriad of ecosystems. So you can often find old-world tarantulas in many places around the world.
Meaning Of The Name
Old World Tarantulas are so named because they are primarily found in the “Old World,” a term historically used to refer to the Eastern Hemisphere and the part of the world before Christopher Columbus discovered the Americas. This section of the world includes Europe, Asia, and Africa. So, when we refer to “Old World Tarantulas,” we are specifically talking about tarantulas that are native to the Old World regions and have similar characteristics.
Urticating Hairs
One of the most notable physical differences between Old and New World tarantulas is the presence of urticating hairs. While both tarantulas possess these hairs, Old World tarantulas have them less pronounced. Urticating hairs serve as a defense mechanism and can be used to deter predators.
Agility
Old World tarantulas are quite nimble and fast and often use their speed as their primary defense against predators. They are among the fastest spider species in the world and are also capable of swift escapes when they they are threatened. In contrast, New World tarantulas are less agile, and as such, can be regarded as a more docile species.
Aggression
Old World tarantulas are far more aggressive and territorial compared to their New World counterparts. They are less likely to tolerate handling and may resort to biting if they are threatened or even handled.
Venom Potency
Old World tarantulas are known for having more potent venom than their New World counterparts. While fatalities from tarantula bites are rare, bites from Old World species can result in hospitalization due to their painful and venomous nature.
Conclusion
Old World tarantulas are incredible creatures found in places like Africa and Asia. These spiders are like the globetrotters of the arachnid world, adapting to all sorts of environments. They stand out from their New World counterparts with features like less irritating hairs, speedy moves, and a bit more attitude.
