Hi @gwajnberg, I always keep jumping around within the phylum Arthropoda, that's why there are posts on insects, arachnids, myriapods (millipedes or centipedes) and to a lesser extent crustaceans, mostly because the latter are more related to aquatic ecosystems and here I don't have much experience; however, I have gotten to post some stuff on terrestrial crustaceans of the suborder Oniscidea.
