About Brookesia bonsi
Brookesia bonsi is a species of chameleon belonging to the family Chamaeleonidae, recognized for its severe endangerment and highly restricted natural range. This small lizard is endemic to the island of Madagascar, specifically found within the humid environments of Namoroka National Park in the northern part of the country. First described by herpetologist Guy A. Ramanantsoa in 1980, the species has since been the subject of scientific interest due to its unique habitat requirements and vulnerable status.
Distribution and Habitat
The natural habitat of Brookesia bonsi is confined to Namoroka National Park, situated in the Soalala District of Mahajanga Province. It is found exclusively in the more humid sections of the park, at elevations ranging from 100 to 200 meters above sea level. The total area believed to be inhabited by this species is less than 100 square kilometers. Surveys conducted in western Madagascar have often failed to detect its presence, highlighting its elusive nature and limited distribution.
Conservation Status
Brookesia bonsi is classified as Critically Endangered by the International Union for Conservation of Nature (IUCN). This dire status is primarily attributed to the small geographic area it occupies and the continuing degradation of its habitat. Factors contributing to this decline include agricultural encroachment and the collection of wood resources within its natural range. A survey in 1996 did not consider the species rare, but a subsequent survey in 2002 failed to locate any individuals, underscoring the precariousness of its population.
Taxonomy and Etymology
The scientific name, Brookesia bonsi, honors French herpetologist Jacques Bons, who was born in 1933. The species was formally described in 1980, and its taxonomic validity has been confirmed by subsequent research and taxonomic databases. It is a member of the Brookesia genus, which is known for its small size and terrestrial habits compared to other chameleons.
Reproduction
Brookesia bonsi reproduces by laying eggs, a characteristic known as being oviparous. Specific details regarding its breeding behaviors, such as clutch size or the length of the incubation period, are not widely documented in the available literature, but this reproductive strategy is common among many lizard species.

What is the conservation status of Brookesia bonsi?
The International Union for Conservation of Nature (IUCN) ranks Brookesia bonsi as Critically Endangered. This status is due to its very limited range and the ongoing decline of its habitat.
How does Brookesia bonsi reproduce?
Brookesia bonsi is an oviparous species, which means it reproduces by laying eggs. Further details about its reproductive cycle, such as clutch size or incubation period, are not extensively documented in available records.
What are the threats to Brookesia bonsi?
The primary threats to Brookesia bonsi are the continuing decline of its habitat, driven by agricultural expansion and wood collection. Its extremely limited distribution also makes it vulnerable to these pressures.
When was Brookesia bonsi first described?
The species Brookesia bonsi was first described as new to science by herpetologist Guy A. Ramanantsoa in 1980. Its taxonomic status has since been validated by subsequent scientific publications.

Calumma oshaughnessyi
O'Shaughnessy's chameleon (Calumma oshaughnessyi) is a lizard species endemic to Madagascar, named after herpetologist Arthur O'Shaughnessy. This chameleon is characterized by its brownish-gray coloration, a darker throat and jaw, and a short, bony structure on the snout in males. It inhabits humid forests in the central highlands of Madagascar and is considered vulnerable due to habitat loss.
Palleon lolontany
Palleon lolontany is a chameleon species native to Madagascar, specifically found in the humid forests of Mount Tsaratanana. First described in 1995, it was later placed in the genus Palleon. The species is currently rated as Near Threatened by the IUCN due to its limited habitat and potential threats from agricultural practices and logging.
