Phymatolithon ferox has short surface margins
resembling pouty lips.
Phymatolithon foveatum’s imbricate surface
results from the numerous secondary pale
raised margins that form across its surface.
Phymatolithon ferox is a pale-pink encrusting coralline
lum engelhartii. This species is a thin, relatively smooth,
commonly known as Pacman (after the arcade game
character) because it characteristically produces small
margins over its entire surface that resemble pouting
lips. This species is weakly attached and most often it is
found growing on top of the thinner individuals of S.
yendoi.
chocolate to purple-brown encrusting coralline with
distinct, pale yellow to almost white, raised margins. It
is able to dominate the sublittoral fringe and immediate subtidal areas because of its relatively fast growth
rate and the degree to which its margin is raised –
growing over everything in its path. Mesophyllum
engelhartii is often associated with the colonial wormshell Dendropoma corallinaceus that often riddle the
coralline with their excavations.
Phymatolithon foveatum is an extremely thin, rosy encrusting coralline with almost white edges. It is common low down on the rocky shore where it may either
form large expanses, or find refuge from being overgrown in the territories of the limpet S. cochlear. This
coralline is often referred to as the ‘imbricate coralline
crust’ because it produces numerous pale raised margins across its entire surface that run more or less parallel to the primary margin. These regenera FVB6V6
