breeding and territorial reasons
no they do not because males use their dewlaps to attract females and and claim their territory if a female has a dewlap then well
It is called a dewlap. They use it to attract the opposite sex and intimadate other males as well as some predators.
RABBITS,FROGS ,LIZARDS, SOME REPTILES (SINCE A dewlap is a longitudinal flap of skin that hangs beneath the lower jaw or neck)
their wings and dewlap varies in color depending on the species. but their body usually blends with their perch, which is barky.
In most breeds the doe has a dewlap and a buck is disqualified if it has a dewlap. Some breeds do not have a dewlap at all. A doe will have a dewlap by the time she is breeding age (which is 6 months:)
No, several other animals have a dewlap
Not that I'm aware of. As far as I know - the only definition is '...a flap of skin that hangs beneath the lower jaw...' - as you would see in some lizards.
Confirm if it is a male or a female,the male has a dewlap,a red under his neck. He is also bigger. Leave them in the cage together. In a week check for eggs. They mate and break up in a few minutes. The male will bob his head and show his dewlap. He will bite the females neck and climb on top of her. Good luck!
a turkey's dewlap is the flap of skin under its neck. Also called a Wattle.
Yes; lizards do use lungs to breathe.
A Mountain Zebra has a dewlap. The other two major breeds of Zebras - Berchell's and Grevy's - do not.
