== Description ==
Capnella are arborescent, some species are lobed. Generally they are grey with brown polyps.  Colour intensity is dependent on light intensity, the higher the intensity of light, the lighter colour of the coral.  They form thick trunks with branches that closely resemble trees.  In stronger currents they form flatter colonies with shorter branches.<ref name=":0" />{{rp|214}}

== Distribution and habitats ==
Kenya Tree [coral](/source/coral)s are widespread throughout the [Indo-pacific](/source/Indo-Pacific) region, from the African coast to the [Western Pacific](/source/Western_Pacific_Ocean).  They are found on coral [reef](/source/reef) slopes in clear water from deep to the shallows with strong tidal currents.  Sometimes found in shadier places and on coral rubble in shallow water close to the shore.<ref name=":0" />{{rp|217}}

== Biology ==
They have [symbiotic algae](/source/Zooxanthellae) from which they obtain most of their nutrients.

[Asexual reproduction](/source/Asexual_reproduction) has been observed. They form distinctive swellings at bottom of a branch which then drops off by [fission](/source/Fission_(biology)) at the swelling.  The branch then secures to a new hold and forms a new colony.  They can stick very quickly and will be firmly rooted within a day.  Colonies can bend and reattach to the rock or by “creeping” and division at the base.<ref name=":0" />{{rp|217}}
