While the blob looked more like a patterned glass art piece than a living being, it is actually formed of hundreds of genetically identical, physiologically interconnected animals called zooids. Similar to coral in their colonial lifestyle, each individual zooid is made up of an outer sleeve-like structure that produces a gelatinous exoskeleton; a mass of organs that can move within the sleeve; and the lophophore, which is a ring of tentacles that filters food particles out of the water. Instead of pooping out waste, a zooid just grows a new sack of organs when the old one fills up.
