Carnivorous Yellow Bladderwort Daintree River - Queensland Australia

With over 200 species Bladderwort is the common name given to the largest genus of carnivorous plants, genus Utricularia. They are found in fresh water and wet soils across all continents other than Antarctica. I found it hard trying to get information on this plant and trying to identify this species but here is a quote I found on the Internet:-

 

 

"Bladderworts possess the most complicated and devious trap of all the carnivorous plants, and is surely one of the wonders of the botanical world.

 

The carnivorous action happens underground, in the water-soaked medium. Each plant produces a great number of bladders, a few to several mm in size, which serve as the mouths of the plant. These bladders have trap doors, and when a free-swimming organism bumps into long hairlike organs attached to the trap doors, the hairlike organs lever the door ajar. The water pressure inside the bladder is lower than the surrounding water, so the partial vacuum instantly sucks the organism inside the trap. The prey has no chance to escape, since it is drawn into the trap in as little as 1/30 of a second. The trapdoor resets and the plant begins digesting the creature."

 

The one I have here was in the swamp land in the Daintree River close to the Ferry crossing. I think my species may be this one:-
