Lubomirskia baikalensis, Baikalospongia bacillifera and B. intermedia are unusually large for freshwater sponges and can reach 1 m (3.3 ft) or more.[2][3] These three are also the most common sponges in Lake Baikal.[2] Most sponges in the lake are typically green when alive because of symbiotic dinoflagellates (zoochlorella), but can also be brownish or yellowish.[4]
