Figure 9 in Five invaginations and shedding of the larval epidermis during development of the hoplonemertean Pantinonemertes californiensis (Nemertea: Hoplonemertea)

Figure 9. Fluorescein diacetate (FDA)-stained late rudiment stage larva of Pantinonemertes californiensis in the act of shedding cells of the larval epidermis. (A) Bright-field view; (B) a confocal projection of 21 1-µm sections of the same larva, showing the brightly- uorescent FDA-labelled cells of the transitory epidermis. Anterior is to the right. The larva was trapped on a slide, fixed by owing formaldehyde in seawater under the coverslip, and the image was collected immediately. Arrows highlight the same shedding cells in both images, which are brightly labelled with FDA.
