Arachnids cover far more then just spiders.

Other insects like Ticks are also members of the arachnid family.

So there is a huge difference between the two powers, as this power only covers spiders. While Arachnid Physiology covers every single family and off-group of the arachnid family.

Ticks, Mites, Scorpions, spiders, and much more cover the basis of Arachnid Physiology.

So you can see the difference here.
