Each zooid is joined to the stolen by a contractile, muscular stalk.
Asexual buds develop on and remain attached to the stolen.
Each of these initially brownish, later transparent tubes contains a single individual. These specimens were collected by Ruth Kelty and Jan Locke from the Bermuda Biological Station for Research, Inc. and the images you see below were captured on an National Science Foundation funded Olympus Provis AX70 with Image pro software.
