Biddulphiaceae

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

Biddulphiaceae is a family of diatoms, 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
