Fusoridae

Discovered deep from within an industrial warehouse, these hulking rectangular giants known as the Fusoridae were at first considered to be some sort of pseudo-occlupanid. Without an oral groove, many occlupanologists even dismissed them as unrelated syntherids. However, recent advances in speculative morphometrics have instead revealed alarming evidence of a massive shift in an occlupanid body plan. The oral hooks have engorged and fused together, curling inwards to form a sturdy central paddle. Meanwhile the oral groove is turned into a mere crescent. These extreme changes are thought to be adaptations to aid it in attaching to its main host, large plastic bags of chips.
