First anecdotal occurrence

According to a local fisherman (Matt Stommel of Woods Hole, Massachusetts, November 2003), an organism resembling D. sp. (and called "macaroni") has been encountered on the bank by fishermen for decades in small "holes" located several miles south of the November 2003 first documented occurrence. Fishermen report it to be mixed with heavy mud in their nets. No specimens of "macaroni" are available for study at this time (Nov. 2003). Note: Recent observations of D. sp. by researchers in the Pacific and Atlantic Ocean basins show it to be attached to hard substrates, never associated with mud or clay seabeds. Source: P. Valentine.
