Save the Venezuelan Marine Chameleon

Call To Action

A changing climate and a rise in plastic pollution are putting the few remaining populations of the Venezuelan Marine Chameleon at risk of extinction. The IUCN projects that, unless something is done, these keystone species will be extinct in the wild by 2050.

The Venezuelan Marine Chameleon (Chamaeleo venezuelensis) is a remarkable aquatic reptile that combines the adaptability of chameleons with the marine lifestyle of iguanas. This unique species boasts a streamlined body, averaging 60 centimeters in length, covered in specialized scales that allow it to seamlessly blend into its oceanic surroundings. Its coloration varies from deep ocean blues and greens to sandy browns, enabling it to camouflage effectively both underwater and on coastal rocks. The chameleon’s large, expressive eyes provide keen vision, and its webbed feet facilitate graceful movement through water.


These fascinating creatures are exclusively found along the coastal regions of Venezuela, particularly thriving in rocky intertidal zones and shallow waters adjacent to coral reefs. They prefer warm tropical waters with a variety of underwater structures for camouflage and shelter.


The Venezuelan Marine Chameleon’s diet mainly consists of small marine creatures, including crustaceans, small fish, and algae. Their specialized tongue can extend rapidly to catch prey, reminiscent of their terrestrial chameleon relatives. They are excellent hunters in the water, employing stealth and precision to secure their meals.


Venezuelan Marine Chameleons have adapted to their aquatic lifestyle by developing salt-excreting glands to manage the salt content from their marine diet. Their ability to change color helps them regulate body temperature and assists in communication with other chameleons. They are known to gather on sun-soaked coastal rocks to bask and thermoregulate.

Reproductive Behaviors

During the breeding season, which typically occurs in the warmer months, male Venezuelan Marine Chameleons display vivid coloration patterns to attract females. These displays involve a combination of color changes, head bobs, and body movements. Once a receptive female is identified, the male accompanies her to nesting sites, which are often well-protected crevices in the coastal rocks.

Females lay small clutches of eggs, carefully burying them in the sand to ensure protection from predators. The females exhibit a remarkable ability to adjust the gender ratio of their offspring by varying the depth at which they bury the eggs – deeper nests tend to produce males, while shallower nests favor females.

Social Behaviors

Venezuelan Marine Chameleons exhibit both solitary and social behaviors. They often congregate in groups on sun-exposed rocks for basking, which not only aids in thermoregulation but also allows for limited social interactions. These gatherings are essential for the exchange of visual signals and establishing dominance hierarchies among males.

Males engage in gentle combat displays to establish territory and mating rights. These displays involve head bobs, extended dewlaps (throat flaps), and lateral movements. These interactions seldom escalate into physical fights, as the primary goal is to assess each other’s size and strength to avoid unnecessary energy expenditure.

Understanding these reproductive and social behaviors is crucial for effective conservation efforts, as disturbance during mating or nesting periods can significantly impact the population dynamics of the Venezuelan Marine Chameleon.

Conservation Threats

Despite their unique adaptations, the Venezuelan Marine Chameleon faces several conservation threats. Coastal development and habitat degradation disrupt their nesting sites and access to prey-rich areas. Pollution from agricultural runoff and plastic waste further affects their ecosystem. Additionally, the illegal pet trade poses a threat to their population as they are coveted for their captivating appearance.

How You Can Help

  1. Support Conservation Efforts: Contribute to local and international organizations focused on protecting coastal habitats in Venezuela. Your support can help establish marine protected areas and enforce sustainable fishing practices.
  2. Promote Responsible Tourism: If visiting coastal areas where these chameleons reside, adhere to guidelines that prevent disturbance to their habitats. Minimize pollution and avoid disrupting their nesting sites.
  3. Educate Others: Raise awareness about the importance of preserving marine chameleon habitats. Use social media, workshops, and community events to inform others about these unique creatures and the threats they face. Use our Social Media Toolkit to spread the word!
  4. Reduce Plastic Use: Participate in beach cleanups and reduce your plastic consumption. Plastic waste poses a significant threat to marine life, including the Venezuelan Marine Chameleon.
  5. Advocate for Stronger Regulations: Support legislation like The Venezuelan Marine Chameleon Coastal Protection Act (SCP096) that protects coastal environments and restricts destructive development practices. Encourage your representatives to prioritize the conservation of unique and endangered species.

By taking these actions, you can contribute to the preservation of the Venezuelan Marine Chameleon and its fragile coastal ecosystem.
