Lizards do push ups to defend their territory at dawn and dusk
A new study has revealed that a Jamaican lizard called the Anolis engages in impressive displays of reptilian strength - push ups, head bobs, and threatening extension of a colourful neck flap called a dewlap - to defend its territory at dawn and dusk.
Many animals of all classes use camouflage to hide their body in the surrounding environment, until being nearly totally invisible when they don't move.
