# Golden Lion Tamarin vs Golden-Headed Lion Tamarin: Key Differences

*Atlantic Forest, Brazil (Rio de Janeiro and Bahia) · JUN 20 2026*

> The golden lion tamarin is uniformly reddish-gold and lives in Rio de Janeiro state, while the golden-headed lion tamarin has a black body with a golden mane and lives in southern Bahia; both are endangered Brazilian primates in the genus Leontopithecus.

They share a genus, a mane and an endangered status, but the golden lion tamarin and golden-headed lion tamarin are easy to tell apart once you know what to look for.

## What are the key takeaways from this briefing?
- The golden lion tamarin (Leontopithecus rosalia) is uniformly reddish-gold; the golden-headed lion tamarin (Leontopithecus chrysomelas) has a black body with a golden mane, limbs and tail base.
- They live in different, non-overlapping parts of Brazil's Atlantic Forest: Rio de Janeiro state versus southern Bahia state.
- Both belong to the genus Leontopithecus, are classified Endangered, and are listed on CITES Appendix I.
- Both are small, tree-dwelling omnivores that usually give birth to twins with shared infant care.
- Because each is restricted to a single region, both depend on protecting connected forest in their own range.

## Two lion tamarins, often confused

The golden lion tamarin and the golden-headed lion tamarin are close cousins in the genus *Leontopithecus*, and at a glance they can look alike. Look a little closer, though, and the differences are obvious. Here is how to tell them apart. For the full profile of the first species, see our [golden lion tamarin species guide](/wildlife-guides/golden-lion-tamarin/).

### Coat colour is the quickest giveaway

The golden lion tamarin (*Leontopithecus rosalia*) is a near-uniform reddish-gold from head to tail. The golden-headed lion tamarin (*Leontopithecus chrysomelas*) is mostly glossy black, with golden fur restricted to its mane, forearms and the base of the tail. If the body is dark and only the "halo" is gold, you are looking at the golden-headed species.

### They live in different parts of Brazil

Both are endemic to Brazil's Atlantic Forest but do not overlap. The golden lion tamarin lives in the lowland forest of Rio de Janeiro state in the southeast. The golden-headed lion tamarin lives far to the north, in southern Bahia state.

### What they share

- **Genus and family.** Both belong to genus *Leontopithecus* in the marmoset and tamarin family, Callitrichidae.
- **Conservation status.** Both are classified Endangered by the IUCN and listed on CITES Appendix I.
- **Lifestyle.** Both are small, diurnal, tree-dwelling omnivores that live in cohesive family groups and typically give birth to twins, with shared infant care.

### Quick comparison table

 |
 Feature | Golden lion tamarin | Golden-headed lion tamarin
| Scientific name | Leontopithecus rosalia | Leontopithecus chrysomelas
| Coat | Uniform reddish-gold | Black body with golden mane, limbs and tail base
| Range | Rio de Janeiro state, Brazil | Southern Bahia state, Brazil
| IUCN status | Endangered | Endangered
| CITES | Appendix I | Appendix I

### Why the distinction matters

Because each species lives in a single, separate region, the loss of forest in one state cannot be offset by the other. Protecting connected habitat in both Rio de Janeiro and Bahia is essential. WARN's partner-funded work supports forest restoration in Brazil; you can read more on our [habitat protection appeal](/appeals/habitats/).

## What do people ask about this briefing?
### What is the difference between a golden lion tamarin and a golden-headed lion tamarin?
The golden lion tamarin is reddish-gold all over and lives in Rio de Janeiro state, Brazil. The golden-headed lion tamarin has a mostly black body with golden fur on its mane, forearms and tail base, and lives in southern Bahia state. They are separate species that do not share a range.

### Are golden lion tamarins and golden-headed lion tamarins related?
Yes. Both are members of the genus Leontopithecus in the family Callitrichidae, making them close relatives, but they are distinct species adapted to different regions of Brazil's Atlantic Forest.

### Which lion tamarin is more endangered?
Both the golden lion tamarin and the golden-headed lion tamarin are currently classified as Endangered on the IUCN Red List and listed on CITES Appendix I, so neither is more threatened by category, though each faces region-specific pressures.
