What are the differences between the black widow and the tarantula?

The black widow and tarantula are well-known spiders with many differences. They look different, have different venom, live in different places, and behave in unique ways. Knowing these differences helps us appreciate these fascinating creatures.

Both spiders have venom, but it’s more dangerous in black widows. A black widow bite can lead to muscle pain, nausea, and breathing problems if not treated. Tarantula bites are painful but usually not dangerous to humans.

Black widows live in dark spots like under logs or in sheds. Tarantulas, however, like open, dry places like deserts and grasslands.

Black widows are shy and only bite when they must. Tarantulas are less aggressive. They usually run away or stand still when threatened.
