Biddulphiaceae

Biddulphiaceae is a family of diatom, the only family in the order Biddulphiales.^[1] The Biddulphiaceae are distinguished from the Eupodiscaceae by their pseudocelli, where the Eupodiscaceae have fully developed ocelli.^[2] Both families commonly inhabit the littoral zone of the ocean, close to the shore.^[3] Sixteen species of Biddulphiaceae are found on the west coast of India.^[4]
