Giant Day Gecko
Phelsuma grandisAlso known as Madagascar Giant Day Gecko
These brilliant green lizards spend their days basking on sunlit tree trunks and broad palm fronds, actively hunting insects and licking sweet nectar. Bold and highly territorial, males engage in head-bobbing displays and vocal clicks to defend their feeding spots from rivals. When threatened by predators, they can slough off large patches of their own skin to escape, leaving the attacker with a mouthful of scales while the gecko flees to regenerate.

Interaction riskLow
- Low
- Moderate
- High
- Very high
- Why interaction risk is low
- Capable of delivering a painful bite if cornered; observe without handling to protect their fragile skin.
- Why it is dangerous
- Can deliver a sharp, defensive bite if grabbed, and their skin tears easily as a defense mechanism, leaving them vulnerable to infection.
- How to recognize a risky encounter
- Look for a brilliant green body up to thirty centimeters long with bright red spots and stripes on the back and head.
- What to do
- Never attempt to catch or hold them; observe their active foraging from a respectful distance.
Responsible observation
- Look up: Scan tree trunks, broad-leafed plants, and sunny walls where they bask.
- Do not touch: Avoid handling because their skin tears easily as a defense mechanism.
- Listen closely: Listen for their soft clicking or squeaking sounds used to communicate.
