What Do Toad Eggs Look Like? Photos Guide

Toad eggs look like long, paired strings of small dark beads inside clear jelly, laid in the shallows of still water. Each egg is dark above and pale below. A single female American toad can lay thousands of eggs, from about 2,000 to 20,000 depending on the source. Frog eggs, by contrast, usually come in clumps or films. This guide assumes the American toad, the most familiar species in North America.

Found a long jelly rope in a pond or ditch? There is a good chance it is toad spawn.

The old title of this post did not name a species, so this article uses the American toad (Anaxyrus americanus) as its example. Other toads differ in detail, but the string shape is the key clue.

Key Takeaways

Toad eggs are laid in long strings, not clumps.
American toad strings are paired and can be many metres long, per the Vermont Reptile and Amphibian Atlas.
Eggs are dark above and white to cream below, and sit in the shallows of still water.
Sources give different clutch sizes, from about 1,840 to 20,000 eggs.
Eggs hatch in days; sources say 3 to 12 days, or less than a week.
Leave wild eggs where they are. Do not move them.

What toad eggs look like

The Vermont Reptile and Amphibian Atlas describes American toad eggs as paired, long strings. The strings run 6 to 20 metres long. The eggs are dark above and white to cream below.

Sussex Wildlife Trust, a UK charity, compares toadspawn to a pearl necklace. That is a good picture: a line of tiny dark beads inside a clear jelly tube.

Where and when toads lay eggs

The Vermont atlas says American toads lay in the shallows of still water, mainly in May, within an April to June window. Fowler toads lay a few weeks later.

The University of Connecticut gives a wider range for its region: breeding runs from March through July, depending on location. The North Carolina Wildlife Resources Commission says mating runs from February through April there. Timing depends on climate and species.

How many eggs?

Sources give different numbers. The University of Connecticut says females lay 2,000 to 20,000 eggs. The Vermont atlas gives 1,840 to 20,000 eggs per mass for the American toad.

The North Carolina commission says 4,000 to 7,000 eggs in two long strips. The differences reflect region and the size of the female.

Source	Eggs per female	Shape
University of Connecticut	2,000 to 20,000	Gelatinous strands
Vermont atlas (American toad)	1,840 to 20,000	Paired long strings
North Carolina WRC	4,000 to 7,000	Two long strips

How toad eggs differ from frog eggs

Toads lay strings. Many frogs lay clumps or films. Live Science compares frog clusters to a bunch of grapes.

The Vermont atlas lists green frog eggs as a surface film, bullfrog eggs as a foamy film, and wood frog eggs as a globular mass. Pickerel frogs lay a dense, spherical clump.

Sussex Wildlife Trust adds that toad tadpoles stay jet black, while frog tadpoles are greenish grey with gold speckles.

From egg to toadlet

The University of Connecticut says eggs hatch 3 to 12 days after laying. The North Carolina commission says in less than a week.

Tadpoles take about two months to develop, according to Connecticut, and few survive to become toads. The North Carolina commission says they change into toads about two months later, at under half an inch long.

What to do if you find eggs

Leave them where they are. Eggs and tadpoles need the water they were laid in, and moving them rarely helps. Collection rules vary by state, so check your state wildlife agency before keeping any wild eggs.

If you touch the water or the strings, wash your hands afterward. Wild amphibians can carry germs. Keep pets away from breeding ponds, because toads release toxins that can sicken dogs.

Health note Wash your hands after contact with pond water or amphibians. Do not let pets mouth toads.
