Life in the wild
What this species is like in its natural environment.
Species overview
The short-beaked echidna is a very unique Australian mammal, combining spines and egg-laying reproduction.
Natural habitat
Found in a wide variety of habitats as long as there are suitable soils for digging and abundant ant nests and termite mounds.
Behavior
Solitary, roaming its territory sniffing the ground for insects, using strong legs to dig quickly.
Special traits
Its long sticky tongue and sensitive snout are perfectly adapted for locating and capturing social invertebrates.
Conservation and threats
Although still relatively common in many areas, habitat fragmentation and introduced predators are constant threats.
Curiosities
Striking details about this species.
- One of the few mammals that lay eggs.
- Body covered in spines to deter predators.
- Digs quickly to semi-bury itself when threatened.
- Can enter torpor states reducing metabolism.
Welfare profile
Aspects to consider in captivity.
Facilities and spaceHigh
In captivity needs enclosures with deep structured substrate allowing digging and hiding.
Light, temperature and environmentMedium
Requires specific diet rich in invertebrates or formulated substitutes, difficult to replicate domestically.
Handling and stressVery delicate
Does not tolerate repeated handling well; stress can affect long-term health.
