A big, bold gecko

Tokay geckos are large lizards with blue-grey skin dotted with orange spots. They climb smooth surfaces using adhesive toe pads covered in millions of microscopic hairs.

The call that named it

The male’s call starts with a series of clicks and builds into a loud “to-kay”, sometimes repeated many times. It is used to defend territory and attract mates. In homes across Asia the call is a familiar night-time sound.

Trade pressure

Tokays are collected in large numbers for traditional medicine and the pet trade, and this has caused local declines. Regulation of trade is an important part of protecting them.
