Cellaria sinuosa

Sinuous cellaria

Cellaria sinuosa

Camaret, France, 12 meters, ML


Cellaria sinuosa is a bryozoan forming ivory colonies of up to 10 cm high. They have a bushy shape with cylindrical branches divided in a dichotomic way. Each branches develop from a dark joint giving the colony an articulated appearance. They are covered on the whole surface with zooids regularly set in longitudinal series. The whitish lophophores are quite invisible to the eye. Colonies live attached to rocks, gravels or shells between 10 and 100 meters deep.


Cellaria sinuosa is reported in the Atlantic Ocean, the Englih Channel, the North Sea and the Mediterranean Sea.
