That's still at best relating insects and crustaceans at the level of (most) fish and mammals. I'm also unclear on where this pancrustacea clade comes in, as most Wikipedia articles for specific species don't even list the clade, just the phylum and class - and fish are still the same class as mammals, while insects and shellfish are not.

Either way, while we eat some mammals and birds, we still don't eat the vast majority of mammals or birds, and we barely eat any reptiles or amphibians or fish.
