Thallus is red and has small bumps, tapering rapidly to a stipe (variable length) and a rounded at the top. This specimen is about 18 cm long and 4 cm wide. The small bumps may be a reproductive function in the life history of the alga. Sparlingia is most often found in high energy areas from the low intertidal to shallow subtidal. A first time spotting on Project Noah.
