Understanding snakes. Protecting people.

A safer encounter starts with knowledge

A snake in the garden can raise many questions. This free Sri Lankan service connects photographs and observations with human expertise, while helping communities learn about snakes and respond appropriately to a bite.

Share a photograph, safely

01

Keep your distance

Use an existing photograph or zoom from a safe position. Never approach or handle a snake for a better image.

02

Tell us what you saw

Add your email, district, habitat and useful observations. Clear context can help an expert assess the photograph.

03

Receive an expert opinion

An acknowledgement confirms receipt. Identification follows human review and may remain uncertain if details are insufficient.

How the service works
