title = "Mushroom bodies and reniform bodies coexisting in crabs cannot both be homologs of the insect mushroom body",
abstract = "In one species of shore crab (Brachyura, Varunidae), a center that supports long-term visual habituation and that matches the reniform body's morphology has been claimed as a homolog of the insect mushroom body despite lacking traits that define it as such. The discovery in a related species of shore crab of a mushroom body possessing those defining traits renders that interpretation unsound. Two phenotypically distinct, coexisting centers cannot both be homologs of the insect mushroom body. The present commentary outlines the history of research leading to misidentification of the reniform body as a mushroom body. One conclusion is that if both centers support learning and memory, this would be viewed as a novel and fascinating attribute of the pancrustacean brain.",

It is understandable that a neuropil comprising a pedunculus-like column and providing discrete volumes of processes could pass muster as a mushroom body homolog in the absence of any other candidate in the crab. Indeed, this likely contributed to the reniform body originally being accorded a mushroom body identity in 2016 (Maza, Sztarker, et al., 2016), before the first modern description of the reniform body (Wolff et al., 2017).
