Why Choose O’Shaughnessy’s Chameleon?

The O’Shaughnessy’s chameleon is valued for its subtle beauty and impressive size. Unlike more colorful species, this giant Malagasy chameleon displays deep greens and browns, blending into forest environments. Males often have a small rostral horn, while females are more streamlined.

Its slow movement and quiet demeanor make it a peaceful reptile to observe in naturalistic enclosures.

Ideal Setup for Forest Chameleons

Housing a forest chameleon requires creating a cool, humid environment that mimics the misty rainforests of Madagascar.

Enclosure setup:

• Type: vertical screen or hybrid enclosure

• Size: at least 24″x24″x48″

• Temps: 68–75°F ambient, 80°F max basking

• Humidity: 70–90%, daily misting + dripper

• Lighting: UVB and soft basking light

• Décor: dense live plants, vines, cork bark for privacy

Because Calumma oshaughnessyi prefers lower light levels, shaded zones within the enclosure are essential.

Diet and Daily Care

The diet of an O’Shaughnessy’s chameleon should be nutrient-rich and supplemented regularly.

Feeding tips:

• Primary insects: roaches, crickets, silkworms

• Occasional feeders: hornworms, isopods

• Supplements: calcium with D3 (2–3x/week), multivitamins (1x/week)

• Water: rely on misting and drippers for hydration

Avoid direct handling—this species thrives with a hands-off approach in a quiet, stable setup.

Conclusion

The O’Shaughnessy’s is a fascinating choice for advanced reptile enthusiasts who appreciate natural behaviors and subtle beauty. With proper habitat control and minimal stress, this forest giant will thrive in a lush bioactive environment.
