The Spectral Saenggul
a flamboyant creature at first glance, males exhibit a secret vibrant array of colorful pulsations only visible to female’s. To be less apparent to predators the male’s true mating colors are displayed in ultraviolet color. They inhabit mangrove swamps. Their modified gills allow for a semi terrestrial life.
Though not particularly agile aerialists males fly backwards, with the aid of their inflatable gas pouch, from tree branch to tree branch flicking their modified feeding quills
(first attempt at a gif and let me tell you, it took me forever to figure it out!)

NOW BACK TO MONTERS
This is another great life-form from Wayne Douglas Barlowe’s book “Expedition,” detailing the scientifically plausible inhabitants of an alien world.
The “Forest Gulper” begins life as a small, winged flier, but matures into a sedentary carnivore with a huge, cavernous mouth and no sonar pits (this planet’s stand-in for eyes). Its breath is attractively sweet to herbivores and the floor of its mouth highly adhesive. The stunted wings beat constantly, presumably to waft its odor.
I bought Expedition recently, and I love it. @.@
