Frog Egg-laying Habits
Some frogs, including many treefrogs, lay single eggs that sink to the bottom of the breeding pond or are attached to submerged vegetation.
Some frogs, including many "true frogs," lay egg clusters, usually attached to emergent (partly exposed) aquatic vegetation.
Surface Film of Eggs
Some frogs, including native Eastern Narrow-mouthed Toads and invasive Cuban Treefrogs, lay eggs in a surface film that floats on the surface of the breeding pond (sometimes attached to plants).
Strings of Eggs
Some frogs, including native and invasive "True Toads," lay eggs in long strings wrapped around emergent vegetation.
