So in addition to crabification, we also have antification. Evolution really just found an energy minima at eight legs, huh?
It's more that the lobster plan (long body) is really quite good in many niches, but the crab plan (wide body, no exposed tail) works better in more productive ecosystems that have more predators. So anything lobster shaped coming up from the deep mud will have to reduce its tail or get sniped by a fish
so wait are we just walking terrestrial lobsters? and.. gorillas are primate crabs maybe?
Carcinisation is a bit more of an adaption to environment (convergent evolution into same-ish shape for the by-chanceb best utility of it ... ie a perfect body) vs niche mimicry which is in relation to another specific species (ie some else's body).
Proper ants only have 6 legs, though. But yeah, these spiders-turned-to-ants would have 8 legs.
Well, and crabs technically have 10 legs, with their foremost pair typically equipped with pincers. 🙃
i'm sure there's at least one ant-mimicking spider that has turned their front legs into extra quasi-pedipalps to blend in better, getting rid of limbs is super easy in evolution (that's where antennae and the existing pedipalps come from, and spinnerets too i presume)
