Remipedes
The remipedes are small insect-like creatures that appeared in The Remipedes. They are multi-legged and blind. They live in caves in the deep ocean where they rely on their sense of hearing, smell, an...

That, and naming conventions... nobody's using Linnean taxonomy!

While I appreciate the original meme, I am a little frustrated by the tetrapod-centricity of most responses.
Picking invertebrates off my list, however, quickly runs into my inability to prioritize.

Honestly, you could do worse for ID keys.

As for drilling predation, frequencies vary from 0.1% successful attack to >30% in Cardiarina (!) but there are signs of size and/or taxon selection ... the little guys might not have been quite as rough on digestion as their larger cousins.

That last one is revisiting the classic Gould and Calloway paper (1980) ... replication is important!

Lingulid pedicles are actually edible, and considered a delicacy in Korea (or so past students from Korea have assured me). Supposedly tastes like a light clam broth.
However (and this may be the anecdote you remember) their lophophore apparently will stick in one's throat.

No gatekeeping! Lots of university collections were built from the Wards catalog.

You better hope so!
Articulates typically have chemical deterrence so bad anemones will spit them out.
There's a story about a brachiopod worker who tried one just to see ... and then turned green puking his guts out.

I would imagine, coming a decade after Ships That Pass In The Night!
Says something that I got through a graduate degree on early Triassic brachiopods in the '90s without that particular paper ever coming to my attention 🤣

I don't know if sea stars leave recognizable predatory traces that could be used for similar studies though.

I wonder if this was a case of mistaken identity (despite brachs having extremely effective chemical deterrent, optimistic gastropods still try to drill one on occasion). Drilling frequencies are typically much lower than on mollusks.

So if you feel grossly inflated and incapable of moving after stuffing yourself to the gills yesterday, you are part of a classic ecological niche! Stay in, don't buy anything, let consumer capitalism go on without you.

There has been some debate historically, with some workers placing them outside of crown group Gastropoda. The general form is dextrally coiled, with one surface flattened and the living chamber expanding upwards as well as outwards during growth. It had an operculum, and movement seems impractical.
