Callophyllis laciniata
This is a foliose species and tends to be very thin,
membranous, soft and fleshy. Fronds are wide and often
much divided or split into broad fan shaped sections and
are bright pink in colour. The edges may be slightly frilly
and reproductive bodies are found in the slightly frilly
edges of the fronds which often form bladelets.. Found in
the lower littoral and sublittoral fringe frequently located
on kelp stipes and holdfasts. May be distinguished from
Cryptopleura sp. by the absence of a midrib or veins.
