Identification
Red sea fan species (Callophyllis spp.) are flattened, fan-shaped red algae with veinless, dichotomously-branched blades. Branch width and length vary between species, though such characteristics are generally not enough to accurately differentiate between species. Confirmation at even the genus level may require microscopic examination. See the AlgaeBase Callophyllis page for genus identification details.
Mature C. heanophylla plants tend to be no more than 10 cm tall and have irregular or regular dichotomous branching.
Habitat & Range
Red sea fan species mostly grow in the subtidal to depths of 20 m, though they may occasionally be found in the low intertidal. They are mostly perennial, and grow on rock, other algae (epiphytic), and animals (epizoic). They are found from northern Alaska to northern Mexico. C. heanophylla is one of the more common species in the genus.
Similar Species
Frilly red ribbon (Palmaria callophylloides), a similar red alga, grows in the high to mid-intertidal.
