Forest of the Weird
Dubbed “forest of the weird,” this alien-like community composed almost exclusively of glass sponges uniformly oriented with the direction of the current was encountered on "Ridge" Seamount during the 2017 Laulima O Ka Moana: Exploring Deep Monument Waters Around Johnston Atoll expedition.
