Range
Corallina vancouveriensis is found from Alaska (USA) to Mexico, and has been seen on the Galapagos Islands.
Habitat
C. vancouveriensis is seen in the low and mid-intertidal zone and tidepools. It is strong enough to handle hours of exposure on rocks.
Morphology and Identification
Corallina vancouveriensis is an articulated coralline (Red algae) with a disk-shaped crustose holdfast. Pink to dark purplish in color and ranges in size from 7-14 cm tall (some can get grow taller than 14 cm). This species has dense, pinnate branching with the axial intergenicula being as tall as they are broad. The axial intergenicula bear adaxially attached branches that are much narrower. There is lateral branching on multiple planes and creates a “squirrel tail” look. C. vancouveriensis is usually taller and less flat compared to C. pinnatifolia and C. officinalis. This is the only articulated coralline in CA that can withstand several hours of exposure on rocks.
