It spends a lot of its time hunting on land. Getting enough oxygen isn't
the limiting factor for big land arthropods. Their problem is keeping
their gills moist. Beyond a certain mass, the gills dry out faster than
the body can remoisten them.
This cannot apply to insects or myriapods, which do not have gills (except
for the juveniles of some insect groups). It may apply to aquatic
chelicerates and custaceans.
