ID quizzes and challenges seem to have become an increasingly popular subject for natural history blogs. I’ve done a few of my own, but my straight up ID challenges are starting to seem a little unimaginative compared to the DNA sequence, crypsis, mimicry, taxonomy fail, and other challenges being offered up by bug blogdom’s more creative types. To step it up a notch, I offer the first Super Crop Challenge. Small structures that we take for granted within a larger context often take on alien qualities when viewed in isolation. Can you identify this structure and the organism that possesses it?

But, clearly, it’s actually a partially submerged hippopotamus in profile. Or else one of those weird flat fish.
I’m going to cast my vote with you for hippopotamus.
Definitely a leiobunine. The coloration and texture looks wrong for a phalangiid, which are generally duller-coloured and leathery rather than crunchy. Maybe Leiobunum verrucosum, but I wouldn’t want to commit to that one.
