Silhouettes of two fucoid taxa from Brave Boat Harbor, Maine showing morphological variability. Detached Ascophyllum nodosum grading from two large fragments (A), to a pair of more proliferous fragments (B), to progressively smaller fronds (C, group of 6), and finally to minute plants of the ecad scorpioides (D, group of 11).
