Taxonomy

Fredericella sultana colonies produce attached and upright branches.

The lophophore is circular, with 16-28 tentacles.

The diagnostic statoblasts (dormant stages) are retained within colony branches and are kidney-shaped, smooth and dark brown when mature (Wood and Okamura, 2005).

Diagnostic description

The statoblast shape and form (absence of float or annulus) distinguish Fredericella sultana from other bryozoans

Lookalikes

Fredericella sultana can be confused with Fredericella indica.

Distinguishing the two species requires careful examination of the surface of the dried statoblast: in Fredericella sultana the statoblast is smooth, in Fredericella indica it is pitted.
