Fan Throated Lizard clicked at pune, India
Males have a loose patch of skin drooping from their throats – it doesn’t sound like much but comes into its own when the lizards’ dating game begins. That’s when males scamper up a rock, strike a cobra pose and unfurl the loose skin into a beautiful fan.
A male fan-throated lizard will use his dewlap to woo a would-be partner by puffing it into a fan, comes in hues of metallic black, orange, blue and cream – or all in one.
In the mating season,
males are seen perched on rocks in open rocky areas, such that their dewlap is visible to all lizards in the surroundings, both of the same and the opposite sex. This behaviour, the researchers say, indicates that male lizards are likely signalling to multiple receivers. Their reproductive success, by finding mates and fending off competitors, depends on successfully communicating this signal.
