Winter is in the air! These icy blue tendrils belong to a bryozoan called Virididentula dentata. Bryozoans, a.k.a. “moss animals,” exist in colonies composed of dozens of individual organisms called “zooids.” They’re prolific invaders, because it’s easy for them to latch onto ship hulls and travel around the world. This bryozoan is native to New Zealand and Australasia, but marine ecologists at the Smithsonian Environmental Research Center spotted during a fouling survey in Hawaii. (Photo: Brianna Tracy-Sawdey)
