On coral reefs, corallines play a significant
role cementing the reef together. This picture shows the pink crustose
corallines with a cuttlefish swimming overhead trying to match the color
of the algae.
Epiphytic corallines: Melobesia mediocris on Phyllospadix is
the light pink algae. The darker purple algae is noncoralline epiphytic
red called Smithora.
Close up of the epiphytes on Phyllospadix.
(Pink is Melobesia and purple is Smithora)
Corallines as an undergrowth layer with
other algae growing above it.
Saxicolous corallines in the intertidal
zone. Also note the snails crawling over the corallines
Dominant in the intertidal zone, corallines
can often cover every surface available.
In the aquarium, corallines are very successful.
Here they have taken over the window sill of the exhibit as well.

There is crust growing on the rock as well
as on the snail (epizoic).
