About Halichondria bowerbanki Burton, 1930
Halichondria bowerbanki, commonly called the yellow sun sponge, is a species of sea sponge belonging to the family Halichondriidae. This sponge grows on rocky surfaces in the shallow subtidal zone; occasional individual specimens can also be found in the intertidal zone growing beneath overhanging rocks. This species has variable physical appearance and structure, and forms irregular, tassel-like branches. Full colonies can grow up to 25 centimeters tall, and individual branches can reach up to 12 centimeters in height. Its color changes with the season: it ranges from beige to brown during the summer, and is light grey to yellow during the winter.
