Female (F) held at right angles to body of the male. The fifth pair of walking legs of the male (1) are inserted into the brood pouch filled with eggs (e) containing zoeae about to hatch. Chelae (ch) of the male are extended at this time. Mating In the aquarium containing females about to release zoeae, the males can be observed walking about on the tips of their dactyls. They appear to be actively searching. Encounters at this time with non-gravid females or females which have either just released their larvae or are about to release lar\ae generally result in mating. Females with eggs in the early stages of development were never observed to Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Lillie, Frank Rattray, 1870-1947; Moore, Carl Richard, 1892-; Redfield, Alfred Clarence, 1890-; Marine Biological Laboratory (Woods Hole, Mass. ); Marine Biological Laboratory (Woods Hole, Mass. ).
