Pakucaris is an extinct genus of bivalved arthropod known from a single species, Pakucaris apatis, found in the Marble Canyon locality of the Burgess Shale in British Columbia, Canada.

Unlike other members of that group, the posterior segments are covered with a separate pygidium shield, covergent on other arthropods like artiopods.

The head has a forward and downward facing pair of moderately sized eyes on short stalks, along with three pairs of cephalic appendages.

The segments of the thorax and pygidium have pairs of thin filamentous limbs divided into 20/21 podomeres, with paddle-like exopods.

It was probably nektobenthic (actively swimming close to the seafloor), and its ecology was likely that of a selective suspension feeder, using its limbs to scrape and/or suspend food particles from the sea floor, before using its limbs to capture and transfer them to the mouth.
