However, because distinguishing a mangrove species is based upon physical and ecological traits rather than family lineage, scientists often differ in what they consider to be a true mangrove.

Share sensitive information only on official, secure websites. In fact, the various species of mangroves aren't necessarily closely related to one another, but they do share the unique capability of growing within reach of the tides in salty soil.

This low diversity means that mangroves of a single species are so similar that the genetic makeup of one individual is almost identical to its neighbor.
