Caiman Project is an Instituto Marcos Daniel's initiative in partnership with ArcelorMittal Tubarão. The broad-snouted caiman (Caiman latirostris) is an Atlantic forest symbolic species. Caiman Project researches and conserves the species, generating technical-scientific health and ecology data of Caiman latirostris in Brazil.

The Atlantic Forest is one of the most important regions on the entire planet. Due to its exuberance and extraordinary diversity, this biome receives a special title that few places in the world have:  Biodiversity Hotspot.

It occupies the entire Brazilian Atlantic coast, covering 17 states and 1.3 million km². It presents several forest formations and associated ecosystems, according to the characteristics of the climate, soil and relief.

It is directly influenced by moisture and winds from the ocean. The distance from the ocean and the strength of this influence, the altitude and the rainfall dispersion regime contribute to the diversity of ecosystems present in the biome.

As the distance from the coast increases, the climate becomes drier and receives less incidence of rain formed in the ocean. Many ecosystems associated with the Atlantic Forest are not typically forested, however, they are of great importance for the preservation of the forest.

All this abundance of resources, diversity and exuberance also explains why our civilization has taken root here. The problem is that for this to happen, much was destroyed and the human occupation of the Atlantic Forest was and still is dramatic.

Free in nature, the papo-amarelo caiman live only in South America. The geographical distribution of the species extends to Brazil, Argentina, Paraguay, Uruguay and Bolivia, in latitudes ranging from 5º S to 34º S and at altitudes of up to 800 m.

More than 70% of the world's population of alligators live in Brazil, in an area that extends from the coastal region of Rio Grande do Norte, through the basins of the São Francisco, Paraná, Paraguay and Uruguay rivers. , until reaching the Mirim lagoon, in Rio Grande do Sul.


The papo-amarelo caiman occurs in ecosystems associated with water and vegetation, such as rivers, swamps, lakes, mangroves, among other environments in the Atlantic Forest, Cerrado, Caatinga and the Pampas.

In Brazil, a large part of the geographic distribution of the alligator-of-papo-amarelo alligator coincides with the remnants of the Atlantic Forest. This important biome, of great wealth and diversity of life, is recognized as a Brazilian National Heritage. The Atlantic Forest is home to more than 20 thousand species of plants.

The Caiman Project, in partnership with the company ArcelorMittal Tubarão, develops environmental awareness activities.


Environmental education activities provide the public with knowledge about the species and its interactions within its habitat, that is, its home.


The great challenge, however, is to lead the public to change their attitude towards the sustainable use of natural resources and the appreciation of life in all its forms.

Therefore, the Caiman Project's environmental education and scientific dissemination program uses different formats for different audiences and objectives, such as:

  • Environmental Education in public and private schools.

  • Cultural events and events.

  • Awareness through images.

  • Scientific tourism.

  • Training of teachers and environmental educators to use alligators as a flagship species

  • in environmental education actions in schools.

  • Social media.

  • Free environmental education at the Projeto Caiman Ecological Center.

Espírito Santo is in the species focal distribution area in Brazil, however, there is no data about their conservation status, as well as how is the Caiman latirostris' population health in the state.

Data poverty about the natural population limits the development of conservation and management plans for the species, as well as decision making.

The study of the populations can substantiate and orient the development of conservation programs and sustainable usage, and also how to establish priority conservation areas.


This way Instituto Marcos Daniel stands out in the systematic study of Atlantic Forest crocodilians generating technical-scientific broad-snouted caiman health and ecology data. 


Projeto Caiman - Atlantic Forest Caimans, emerges among the main research and caiman conservation initiatives. The activities include research development, environmental education, and young researchers' formation through scientific initiation programs. 


It's about a pioneer project, fundamental to the state's biodiversity conservation.
