At a glance, this cut-out paper model of a nautiloid looks promising. Know, however, that it requires manual dexterity for cutting out neatly and for folding and attaching the tabs. This particular mollusk model is quite difficult to assemble, and the directions are underdeveloped, so you may only want to consider using it with a middle school marine biology unit. Also, glue will not do! You need to have clear tape on hand as an adhesive.
