Comprehensive DescriptionRead full entry
Allapasus aurantiacus is a torquaratorid acorn worm characterized by a small, plate-like proboscis skeleton intervening between the stomochoard and the main course of the digestive tract, lateral wings running along the entire length of the trunk, and sacculate hepatic intestines shorter than the posthepatic intestine. The proboscis and collar are light orange and the trunk ranges from beige to light orange. The most remarkable feature of A. aurantiacus is the externalization of the ovaries. [Holland et al., 2012].
