Antithamnion defectum

A. defectum, microscopic

Antithamnion defectum is a beautiful and tiny red alga found in the cold temperate Pacific waters off the coast of North America, although other members of the genus are found from the poles to the tropics. It is often epiphytic, growing on a wide variety of other algae, as well as on rocks, buoy lines and wharf pilings. It often appears to the naked eye as slimy red scum, but when you take the time to look closer, its beauty will win you over. Check out the links below to learn more.
