Project Description

Coral leaf seaweed (Bossiella spp. and Calliarthron spp.) can be difficult to identify in their natural setting.  These upright branching and articulated coralline algae consist of hard segments as cell walls contain calcium carbonate.  The joints are not calcified which allow the algae to move in the ocean current.  Coral leaf seaweed can grow to around 10 inches (25 cm), with a range from northern Alaska to northern Mexico.
