Semiaquatic plantsEdit

Semiaquatic plants include:


  1. ^ At least one individual of a normally fully terrestrial praying mantis species, Hierodula tenuidentata, has learned to opportunistically prey on fish.[1]
  2. ^ Technically, most land crabs fall into this category, since most must return to bodies of water to release their eggs; the few exceptions, such as members of genus Geosesarma,[2] are found among the Grapsidae (sensu lato) and Potamoidea (sensu lato).[3]
