Desert Rain Frog Facts: Size, Range, Squeak and Status

The desert rain frog (Breviceps macrops) is a tiny, plump frog that lives only in coastal sand dunes of northern South Africa and southern Namibia. Adults are about 4 to 6 cm long. It spends the day buried in sand, feeds at night on termites and other insects, and makes a high squeak. In July 2026 the IUCN moved it from Near Threatened to Vulnerable.

Few frogs have a face as memorable as the desert rain frog. It is round, wide-eyed and short-snouted, and its squeaky call went viral online.

Here is what reliable sources say about its size, range, diet and breeding, and why its future looks worse than its cute image suggests. For the wider family, see our article on rain frogs.

Key Takeaways

• The desert rain frog lives in a coastal strip about 10 km wide in South Africa and Namibia.
• It is 4 to 6 cm long, roughly the size of a ping pong ball.
• It cannot hop. It waddles across sand and burrows by day.
• Termites are a key food, and it can eat up to 100 in one sitting.
• The IUCN moved it to Vulnerable in July 2026, and it is not suited to captivity.

How big is the desert rain frog?

Mongabay gives a length of 4 to 6 cm (1.6 to 2.4 in). Discover Wildlife compares the frog to a ping pong ball and describes a plump body, bulging eyes, a short snout and short limbs. IFLScience uses a marshmallow comparison.

So the sources agree that this is a very small frog. Body shape is the main reason people call it cute, and it is also why it moves so slowly.

Where it lives

Mongabay reports that it lives only in white coastal sand dunes of northern South Africa and southern Namibia, within 10 to 12 km of the coast. Researchers identified six distinct habitat locations in the Succulent Karoo biome.

IFLScience describes the range on the Namaqualand coast of South Africa extending into Namibia, with dune habitat about 10 km wide. This is an extremely small range for a vertebrate.

Life in the dunes

Mongabay says the frog has no permanent fresh water and absorbs moisture from coastal fog. It spends most of its life buried in moist sand.

Discover Wildlife says it hides deep in sand by day to escape the heat and emerges at night. It cannot hop or leap, so it waddles and may walk up to about 50 yards while foraging. When threatened, it freezes.

IFLScience reports that the frogs wait underground for foggy nights and then call to find a mate.

What does it eat?

Discover Wildlife says it eats mostly insects, especially termites, and can eat up to 100 in one sitting. Reptiles Magazine lists ants, termites, beetles, moths, woodlice, amphipods, young millipedes and caterpillars.

Both sources describe a night feeder that emerges after rain or fog. Exact diet shares in the wild are not given.

The squeak

Reptiles Magazine mentions a “cute squeak,” and IFLScience compares the high-pitched call to a dog toy. The sources reviewed give no technical detail on pitch or call rate.

The frog became widely known after a viral video in 2013. Reptiles Magazine says suspected demand grew after that, which raises welfare and conservation concerns.

Predators

Discover Wildlife names two dune hunters. One is the Namaqua dwarf adder, a snake that lies in wait in the sand and can strike only about four inches. The other is the Parabuthus scorpion, which senses tiny movements.

Staying still is the frog’s main defence, according to the same article. Its relatives inflate when threatened, a trait covered in our rain frog guide.

Breeding

Reproduction happens in the rainy season, according to Reptiles Magazine. IFLScience quotes researcher Louis du Preez describing a “really unique” breeding biology but gives few details.

Related Breviceps frogs develop directly into froglets, but the sources reviewed do not confirm the details for this species, so none are stated here.

Is it endangered?

Yes. Reptiles Magazine and Mongabay report that the IUCN moved the species from Near Threatened to Vulnerable in July 2026. The IUCN projects a decline of around 20% over the next decade without conservation action.

Threats include diamond mining, energy and infrastructure development, a proposed green hydrogen project, heat stress and climate change. The projects could affect about one third of the range in South Africa and two thirds in Namibia over 20 years.

Mongabay says no coordinated conservation efforts are in place yet, and that researchers have begun a Green Status assessment.

Can you keep one?

Reptiles Magazine states that desert rain frogs are not suitable as pets, are exclusively wild caught and do not acclimate to captivity. It notes unconfirmed breeding reports and no documented programs.

Frequently Asked Questions

How big is a desert rain frog?

About 4 to 6 cm long according to Mongabay, similar to a ping pong ball.

Where do desert rain frogs live?

Only in coastal dunes of northern South Africa and southern Namibia, within roughly 10 to 12 km of the coast.

Why does it squeak?

IFLScience reports the frogs call to find a mate after waiting underground for foggy nights. The squeak is part of that courtship.

What does it eat?

Mostly insects such as termites, ants, beetles and moths. It can eat up to 100 termites at once, per Discover Wildlife.

Is it endangered?

The IUCN lists it as Vulnerable since July 2026, with a projected 20% decline over a decade.

Can I keep one?

No. Reptiles Magazine says they are wild caught and do not acclimate to captivity.

Bottom Line

The desert rain frog is tiny, shy and tied to one narrow strip of coast. Its fame helped raise awareness, and it also raised demand that the species cannot afford.
