Do Jellyfish Make Jelly?
No. Since jellyfish are not actually fish, the term “jellyfish” is a misnomer, and American public aquariums have popularized use of the terms jellies or sea jellies instead. The word “jellyfish” is used to denote several different kinds of cnidarians, all of which have a basic body structure that resembles an umbrella, including scyphozoans, staurozoans (stalked jellyfish), hydrozoans, and cubozoans (box jellyfish). Jelly is made from flavoured sugar crystals bound with a binding agent such as gelatine.
