Secondary circular aboral vesicle. Size 35 mm x 21.5 mm.
Collected by scholar O. Carpenter from an industrial warehouse in the State of Washington, little information exists about this mysterious archignathid, or what its secondary vesicle is used for. Its cogener, H. therapion, was found inside a first-aid kit in the Netherlands, so it is possible this occlupanid exists in a similarly rarified environment. HORG is actively searching for more specimens and data of this occlupanid. The secondary vesicle and oral groove are smaller than that of H. therapion.
