Tiger Salamander
Scientific name: Ambystoma tigrinum
Large salamander with robust body and mottled or striped patterns, native to North America.
Quick facts
- Approximate size15–30 cm
- Average weight50–120 g
- Life expectancy10–15 years
- ActivityNocturnal
Basic information
- Home: grasslands, forests and agricultural areas with temporary ponds for breeding.
- Food: invertebrates, small amphibians and other animals found underground or on the surface.
- Sexual dimorphism: males have a slightly longer tail and more prominent cloaca during breeding season.
- Predators: birds, mammals, fish and snakes; larvae are very vulnerable.
Life in the wild
What this species is like in its natural environment, with the climate, shelters and resources it needs.
Species overview
The tiger salamander is one of the largest urodeles in North America and an important component of temporary pond ecosystems.
Natural habitat
Depends on seasonal ponds for breeding and suitable soils for digging and sheltering the rest of the year.
Behavior
It is mainly subterranean, emerging on humid nights to feed and migrate to breeding areas.
Special traits
Its plasticity in larval development and size make it very interesting from a biological standpoint.
Conservation and threats
Destruction of temporary ponds, pollution and habitat fragmentation threaten some populations.
Curiosities
Striking details about this species that help better understand its biology and role in ecosystems.
- Larvae can present cannibalistic forms in highly populated ponds.
- Digs burrows or uses other animals' burrows as shelter.
- Some populations can maintain larval characteristics throughout life (neoteny).
- A species frequently used in development and ecology studies.
Welfare profile
Summary of the most critical points if this species is kept in captivity at specialized centers.
Facilities and spaceMedium
In captivity requires terrariums with deep and humid substrate, with access to shelters.
Water, light and microclimateHigh
Needs occasional access to appropriate water to observe natural breeding behaviors.
Handling and stressMedium
Tolerates excessive heat and dehydration poorly.
Tiger Salamander in captivity
General information intended for professional facilities and educational projects. Not intended to encourage capture or improvised keeping of wild amphibians.
⚠️ Amphibians are particularly vulnerable to pollution, emerging diseases and improper handling. Before keeping species like this, it is essential to review local regulations and seek qualified advice.
Suitable facilities
Should only be kept by people with prior knowledge about urodeles and their specific needs.
Feeding in responsible centers
- Feeding includes earthworms, crickets and other suitable invertebrates.
- Varied prey according to animal size.
- Calcium and vitamin supplementation.
Handling and welfare
Handling should be minimal, always with clean and moist hands or soft tools.
Ethical message
Can be used in education to explain complex life cycles and the importance of temporary ponds.
This section has an educational purpose. Amphibian conservation involves, above all, protecting ponds, rivers, forests and wetlands, and avoiding irresponsible release of exotic species.
