Common Toad vs Natterjack Toad for Kids
The Common Toad, Bufo bufo, and Natterjack Toad, Epidalea calamita, are both warty European amphibians, but their clues tell different stories. The Common Toad is larger, widespread and often breeds in deeper permanent ponds. The smaller Natterjack has a thin yellow stripe down its back, runs instead of hopping and depends on open sandy places with shallow warm pools. In Britain it is rare and fully protected.
Common Toad
- Type: Living
- Group: True toad family species (Bufo bufo)
- Known for: Broad warty body, copper-colored eyes, slow walking, seasonal journeys to deeper breeding ponds and double-row spawn strings
- Diet: Carnivore; insects, spiders, worms, slugs and snails
- Special skill: Follows familiar spring routes back to ancestral breeding ponds and releases skin toxins that discourage predators
Natterjack Toad
- Type: Living
- Group: True toad family species (Epidalea calamita)
- Known for: Thin yellow back stripe, greenish eyes, short legs that run, extremely loud rasping call and rare sandy habitats
- Diet: Carnivore; moths, beetles, woodlice, ants and other small invertebrates
- Special skill: Runs in short bursts on very short legs and makes a rasping breeding call that can carry as far as about 2 km
Quick Answer
A Common Toad is usually larger, broad-bodied and brown or olive, with copper eyes. A Natterjack Toad is smaller and normally shows a pale yellow line down the middle of its back. It has very short legs, greenish eyes and a booming rasping call. Common Toad spawn contains two egg rows; Natterjack spawn usually contains one.

How Are Common and Natterjack Toads Alike?
- Both are true toads with dry-looking warty skin and poison glands behind the eyes.
- Both begin life as eggs in water and change from tadpoles into air-breathing toadlets.
- Both are most active at night and hunt small invertebrates.
- Both usually walk or run more than they hop like frogs.
- Both gather at pools in spring so males can call and females can lay strings of spawn.
How Are Common and Natterjack Toads Different?
- Common Toads are usually larger, while Natterjacks rarely reach the biggest female Common Toad sizes.
- A Natterjack normally has a clear yellow back stripe; a Common Toad usually does not.
- Natterjacks run on short legs and call far more loudly than Common Toads.
- Common Toads favor deeper ponds, while Natterjacks need shallow warm breeding pools in open sandy habitats.
- Common Toad spawn has two egg rows, while Natterjack spawn usually has one row.
Common vs Natterjack Toad Adaptation Showdown
- Size – Common Toad: Large females can reach about 10 cm, longer and bulkier than most Natterjack Toads.
- Speed – Natterjack Toad: Its very short legs power a quick mouse-like run across open sand instead of long hops.
- Strength – Common Toad: Its larger, heavier body gives it more total pushing power; this is not a fight prediction.
- Stealth – Common Toad: Variable brown and olive colors blend into soil, leaf litter, bark and garden ground.
- Social – Natterjack Toad: Breeding males form noisy choruses whose overlapping calls can carry across a dune system.
- Swimming – Common Toad: Neither is a graceful water specialist, but Natterjacks are notably poor swimmers and choose shallow pools.
- Weirdest – Natterjack Toad: A tiny runner with a yellow racing stripe can make a rasp loud enough to be heard around 2 km away.
Fun Common Toad vs Natterjack Toad Facts
The Toad That Runs
Natterjacks have unusually short hind legs. Instead of making big frog-like leaps, they scurry in short, quick bursts across open ground.
One Row or Two
Both species lay jelly strings, but Common Toad eggs usually sit in two rows. Natterjack eggs usually form a single row.
A Two-Kilometer Voice
On calm spring nights, male Natterjack Toads inflate their vocal sacs and produce repeated rolling rasps that may carry about 2 km.
Back to the Old Pond
Common Toads often return along traditional routes to the same breeding ponds each spring, sometimes crossing busy roads on the journey.
Safe Behind the Warts
The bumps are not contagious warts. Skin glands release unpleasant toxins that make many predators drop or avoid a toad.

Common Toad vs Natterjack Toad FAQ
Can a toad give you warts?
No. Human warts are caused by viruses, not by touching the bumpy skin of a toad.
Why is the Natterjack Toad so loud?
Males call to attract females and announce themselves at scattered shallow breeding pools.
Why does a Natterjack have a yellow stripe?
The pale line is a useful species clue, but scientists do not know one simple purpose that explains it in every situation.
Are Natterjack Toads rare in Britain?
Yes. They survive at a limited number of special sites and receive strict legal protection.
Should I move toad spawn?
Usually no. Leave spawn in its pond and ask a local wildlife organization for advice if the site faces immediate danger.

Decode the Toad Spawn Strings
Decode the Toad Spawn Strings
Use two lengths of yarn as jelly strings. Place paper dots in two side-by-side rows for Common Toad eggs and one row for Natterjack eggs. Add clue cards for copper eyes, green eyes, yellow stripe, deep pond, shallow pool, walking and running, then sort every card under the correct species.
