The developing eggs of Agalychnis moreletii, also known as the Morelet’s tree frog. These frogs are native to Belize, El Salvador, Guatemala, Honduras, and Mexico. They mostly breed in the summer months, depositing clutches of 50 to 75 eggs on leaves or ledges which hang over a body of water. When the eggs hatch, the tadpoles fall into the water to complete their development. Images by Dr. Peter Janzen.
