Summarize this article for a 10 year old
Desmonema is a genus of jellyfish under the Cyaneidae family found in colder waters near the Antarctic region and off of the coast of Argentina.[2][3] They have a bell diameter that can extend over 1 meter and wide tentacles that are grouped together in clusters.[3][4][5] They share similar anatomical and physiological structures to the genus Cyanea.[4] Their sophisticated structures like the thick tentacles, sensory systems, and gastrovascular system allow Desmonema to easily capture and extracellularly digest their prey.[6] In recent years, Desmonema were reported to have a commensal relationship with fishes under the Trachurus genus and a parasitic relationship with specimens of the Hyperia genus.[7][8] The genus name derives from the Ancient Greek desmós (δεσμός), meaning "bond", and nêma (νῆμᾰ), meaning "thread".
