But thatā€™s the thing, Iā€™m hooked on clades! If a Stink bug is a bug, and a starfish is a bug, then the last common ancestor of the stink bug and the starfish must be a bug. And thatā€™s my ancestor! Iā€™m a bug, Transcyberism! A big bug, with so many derived features that I donā€™t look buggy at all.
Similarly the octopus: legs, no spine, and an exoskeleton. An exoskeleton? Yes, a highly modified exoskeleton, currently in use as a beak. The beak of the squid is a homolog to the shell of the snail.
I think I did not stop being a bug when I grew a spine. Just like I didnā€™t stop being a tetrapod when I stood upright.
And as long as Iā€™m calling myself a bug, how can I exclude this handsome young fellow?

Exoskeleton, check. Itā€™s made of cellulose!
No spine at all, check.
Legs? Itā€™s a stretch, but there is one flexible limb used for locomotion. So Iā€™m counting it.
We have a bug! A single celled bug. Therefore, thinking with clades, all animals are bugs, even the coral polyp.
You can certainly argue that this convention makes ā€œbugā€ a meaningless term. But I disagree. A bug is any living thing with a special place in my heart <3
