Description:
Schizoporella cornuta forms encrusting colonies that are pink to salmon in color. Zooids are oval to hexagonal and measure approximately 0.01 X 0.001 mm in size. Heavy calcification between zooids obscures distinct boundaries between individuals. The frontal surface is perforated by many tiny pores. The orifice is semicircular. Avicularia are elliptical and may be single or paired. 

Habitat:.
Typical habitats for bryozoans in the Indian River Lagoon include seagrasses, mangrove roots, drift algae, oyster reef, dock, pilings, breakwaters, and man-made debris.  S. cornuta was most commonly found along the coastline on beach rocks and dead shells.  It is most abundant on beach rock and dead shells along the coastline near Walton Rocks and Seminole Shores from October through December.

Range:
S. cornuta is likely to range from Woods Hole, Massachusetts south to the Caribbean.  It is also known in the eastern Atlantic along the West African coast.
  While S. cornuta occurs within the Indian River Lagoon, it is more common at coastal locations.

Studies (Bullivant 1967; 1968) have shown that the average individual zooid in a bryozoan colony can filter approximately 1/3 ounce (8.8 ml) of water per day through its body - an amazing feat for an organism measuring only 3/100s of an inch in height!
