Do bones and joints make pushing and pulling easier compared to invertebrate arms and tentacles? Why? What about constriction? Can boa constrictors do it harder than arms and tentacles?
In: Biology
in general invertabrates with hard shells such as ants and crabs etc are much stonger than the same sized vertabrate would be(aka by body to force ratio). that said, it is impossible for shelled invertabrates to get as large as vertabrates due to issues like their exoskeleton being to heavy to move. so in that sense vertabrates have evolved to be stronger.
