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?
