secondary oral groove. 35 mm x 21 mm.
Discovered by occlupanologist EF Lipton, D. vugada is one of the more puzzling of the occlupanids. The function of the secondary oral groove remains an enthralling mystery. Some researchers think it could be analogous to many fish with eyespots on their tails, but nobody seems to know what predator D. vugada would be trying to avoid. In 2021 Field Researcher W. Sage documented several specimens lashed fast to their bagel-bag hosts, both oral grooves grabbing hold in a unique display of double torsion.
