And in Australia, the mangrove forests are renowned for the massive saltwater crocodile, a reptile that can reach up to 17 feet! Pneumatophores, like these cone roots, help the tree gain access to oxygen even when the roots are partially submerged. Propagules of Rhizophoraare able to grow over a year after they are released from their parent tree, while the white mangrove, Laguncularia racemosa, floats for up to 24 days, though it starts losing its ability to take root after eight.
