Bladderworts are one of the most odd traps of any carnivorous plants. As their name suggest they take the form of a small hollow bladder with a strong vacuum inside.
Long projections extend outwards, drawing the prey towards a trapdoor which sucks its prey inside. The door then snaps shut and seals itself. The water is then pumped out and the bladder starts
to digest its prey. A single bladder traps many prey.
Many species live in the water, these include ones native to the UK which is found in bogs and fens of Europe.
There are also terrestrial Bladderworts which grow in frost free environments in the same boggy areas as sundews and butterworts. Other warm loving forms include ones which grow for just one year and die to prevent drying out.
The largest and biggest are the epiphytic Bladderworts , these grow on trees and cliff tops and several species grow along with Heliamphora on the Tepus mountains of South America.
It is the flowers that are really fine, many look like snapdragons, others look like highly coloured orchids.
