Tarantulas vs. Spiders — What's the Difference?

Tarantulas belong to the Theraphosidae family, characterized by their large size and hairy bodies, making them distinct within the spider world. They are often kept as pets due to their generally docile nature and fascinating behaviors. On the other hand, spiders encompass a vast array of species across different families, showcasing a wide range of sizes, colors, and habits. This diversity includes everything from the tiny, common house spider to the more venomous species like black widows.

Tarantulas have a specific hunting method, relying on ambush and physical power to subdue their prey, reflecting their more primitive lineage. They lack the speed and agility of some smaller spiders but compensate with strength and their imposing presence. In contrast, spiders employ various hunting strategies, including web-building for trapping insects, active hunting without webs, and even jumping or running down their prey, demonstrating a wide adaptive range to different environments.

Regarding habitat, tarantulas prefer warm, dry, or humid environments, often burrowing underground or residing in natural crevices. Their habitats are primarily in deserts and tropical rainforests. Spiders, however, are found in nearly every part of the world, from the highest mountains to the interiors of homes, adapting to a multitude of environments and climates, showcasing their incredible versatility.

Tarantulas generally have a slower metabolism and can live for several years, with some females reaching ages up to 20 years or more. This longevity is unusual among spiders, many of which have much shorter life spans, sometimes only a single season. The lifespan of spiders varies greatly by species, with some living a few months to a couple of years.

The breeding practices of tarantulas also set them apart. They engage in a delicate mating ritual that can be dangerous for the male if not carefully executed. In contrast, spider mating practices vary widely, with some species exhibiting complex courtship behaviors, while others may be more straightforward or even fatal for the male.
