Eggs of the whistling frog
Freshly layed eggs belonging to the whistling frog,Eleutherodactylus urichi shrevei from the Caribbean island of St. Vincent. These frogs lay clutches of gelatinous eggs in damp crevices on land which hatch directly into froglets. Because hatching occurs at a relatively advanced state of development each egg contains a large yolk sac. In this way whistling frogs have done away with the need for water altogether in their life cycles. The evolution of a terrestrial breeding habit was probably responsible for the great success of this genus. The different species are difficult to identify as most are small & brown & very similar in appearance
