Crocodilurus amazonicus has been assessed as Least Concern owing to its large distribution. Although this species is locally threatened by deforestation; these factors are not considered to be major widespread threats and this species is not thought to be undergoing a population decline.

Geographic Range [top]

Range Description:This species is found in Colombia, Venezuela, French Guiana, Brazil (in the states of Amazonas, Para, Amapa, Mato Grosso, Roraima and Rondonia), Peru (Rio Orosa), and possibly in Guyana and Suriname. This species is confined to local and small populations in the western portion of its range (W. Lamar pers. comm. 2010).

Population [top]

Population:This species is locally common in areas of seasonally flooded forests along all large rivers of Amazonia (M. Martins pers. comm. 2010).
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This species is a semi-aquatic lizard known from the margins of rivers, lakes and from inundated forest. Martins (2006) states that the species is always associated with flooded forests, and has never been seen in streams through non-flooded forests.

This species feeds on terrestrial and aquatic vertebrates and invertebrates including amphibians, reptiles, fish, crabs and spiders. Vertebrates form about one third of its diet.

Threats [top]

Major Threat(s): It is unlikely that any major threat is impacting this species; however, it may be locally threatened as a result of deforestation and urban expansion.

Conservation Actions [top]

Conservation Actions: This species is a CITES Appendix II species. In many places its distribution coincides with protected areas (e.g. it certainly occurs in almost all large reserves in Brazilian Amazonia, which represent more that 200,000 km² of protected forests), probably providing safeguards to threats such as deforestation (M. Martins pers. comm. 2010).
