Hallangiidae

National Science Foundation - Turbellarian Taxonomic Database cc-by-nc-sa-3.0

Hallangiidae is a family of acoel flatworms. Individuals can grow to 5 mm. They rely on ciliary gliding to move around.

URI: http://eol.org/schema/terms/ciliary_gliding
Definition: a type of locomotion in which an animal moves on a secreted layer of mucus, propelled by the beating of cilia. It is characteristic of small, soft-bodied invertebrates.
