Fig. 1. The reproduction of Gastrotheca riobambae. (A) Female incubating embryos. The pouch occupies the back and the sides of the body and extends to the back of the head. The pouch aperture (arrow) is rostral to the cloaca. (B) Diagrams of the pouch aperture. The borders of the pouch aperture are separated when the pouch is open, and come together at the mid-line when the pouch is closed. (C) Longitudinal section through pouch and dorsal skin. The pouch is continuous with the dorsal skin at the level of the pouch aperture. (D) Section of an embryo within the pouch. A large embryonic chamber separates the embryo from the pouch-bell gill association. (E) The pouch-bell gill association at higher magnification. The fertilization envelope and egg jelly capsule separate the pouch from the bell gills. Image in (B) is modified from del Pino (1983). Micrograph in (C) by Ruth E. Ruiz. Images in (C, D) are reproduced from Schmid et al. (2012). bg: bell gill, c: cloaca, e: embryo, ec: embryonic chamber, j: fertilization envelope and egg jelly, p: pouch, pa: pouch aperture, p-bg: pouch bell gill association, s: skin.
