The Orinoco Crocodile Crocodylus intermedius is distributed in the northern part of South America, occurring in both Colombia and Venezuela (Medem 1983). The Orinoco Crocodile is one of the largest crocodylian species extant in the world (largest individual recorded 669 cm total length; Humboldt 1860 in Medem 1983). This species dwells a variety of habitats including rivers in tropical evergreen forest, piedmont streams in the foothills of the Andes, and seasonal rivers in savannas (Medem 1983).

Females nest in riverbanks between January and February (dry season) with hatchlings emerging around three months later, generally synchronized with the beginning of the wet season (Seijas et al. 2010). Continuing threats are habitat change, habitat fragmentation, and pollution due to riverside development and human occupancy. An inferred reduction in population size of more than 80% over three generations (75 years) due to species over-hunting in the early and mid 1900s meets the criterion A threshold for Critically Endangered.

Hi, I’m Palm Oil Detective’s Editor in Chief. Palm Oil Detectives is partly a consumer website about palm oil in products and partly an online community for writers, scientists, conservationists, artists and musicians to showcase their work and express their love for endangered species. I have a strong voice for creatures great and small threatened by deforestation. With our collective power we can shift the greed of the retail and industrial agriculture sectors and through strong campaigning we can stop them cutting down forests. Be bold! Be courageous! Join the #Boycott4Wildlife and stand up for the animals with your supermarket choices
