Remarkable Reproductive Behavior in Dwarf Hemiphractids.
|Flectonotus fitzgeraldi. Female w/eggs. JCM|
Flectonotus pygmaeus, on the other hand actually has a fold of skin that forms a pouch and during amplexus, the female releases the mucus secretion, the male beats it into a foam, and as the eggs are laid, the male pushes the eggs into the skin folds - the pouch. The eggs are closely packed together but there is no egg matrix, and the eggs can be removed- they are not attached to each other. The female started to forage within 24 hours. After 23-26 days egg sac starts to split and the female transfers the tads to a leaf axial pool. She submerges a third of her body and the tadpoles swim out. The tadpoles do not feed, they continue to metamorphosis using stored yolk for another 11-17 days.
The authors remove the three species of Brazilian Flectonotus and reassign them to the genus Fritziana. The entire article can be found on-line.
