- crassicorpa (Martyn, 1997)
- External morphology
Second oral groove bursting out of aboral region like a tiny Quato. Size is a whopping 56 mm x 43 mm.
This is without a doubt the biggest occlupanid ever found. While definitely a haplognathid, the huge size and bizarre features leave much to the imagination. Specimens have only been collected from urban farmer’s markets.
