Q: How many carnivorous plants exist?
A:
The famous Venus flytrap is only one of many species of carnivorous plants. More
than 660 species and subspecies of carnivorous plants have been described (although humans
have caused some to become extinct).
The genus with the largest number of species (over two hundred)
is Utricularia, but many other genera
exist and this FAQ discusses them all.
I have prepared
a taxonomical breakdown
of all the different carnivorous genera, sorted by botanical Order and Family. Looking at it
you will see that many plants are carnivorous!
