Figure 2 in Five invaginations and shedding of the larval epidermis during development of the hoplonemertean Pantinonemertes californiensis (Nemertea: Hoplonemertea)

Figure 2. Planuliform larva of Pantinonemertes californiensis. (A) Newly-hatched invagination stage larva of P. californiensis is uniformly ciliated, has an apical tuft (ap) and posterior cirrus (pc); (B) late rudiment stage larva (3 days old at 15–16◦C) has a distinct proboscis rudiment (pb) and two ocelli; (C) late rudiment stage larva in the process of shedding ciliated cells of its larval epidermis from around the mouth (m); (D) a chain of ciliated larval epidermal cells shed and left behind by a larva of P. californiensis. Scale bars 50 µm.
