Finally, although a few nemerteans
(milky ribbon worms--Cerebratulus lacteus) were encountered in this study, other work that is being conducted concomitantly in areas around Casco Bay (southern Maine) by one of the authors (B.
For all treatments, nemerteans
were held in small petri dishes (100 mm X 15 mm) filled with artificial seawater (30 ppt), and maintained at room temperature (24-25 [degrees]C) in an incubator (Innova 4200, New Brunswick Scientific, Enfield, CT) connected to a timed lighting system (12 h light/12 h dark).

Terrestrial decapods, amphipods, and nemerteans
evolved at various times during the Cenozoic, but are cryptozoic, or are tied to aquatic systems for reproduction, and thus are not considered fully terrestrial.
Animals were separated into their major groups: annelids, crustaceans, mollusks, nemerteans
, ophiuroids, sipunculids, and others and put on aluminum pans.
