What causes deep sea fans?
Abyssal (or submarine) fans are formed from turbidity currents. These currents begin when a geologic activity pushes sediments over the edge of a continental shelf and down the continental slope, creating an underwater landslide.
What do sea fans eat?
Feeding. Sea fans use their polyps to trap small food particles, such as phytoplankton and bacteria. The sea fan usually grows so that it is best oriented for the prevailing water current to flow over the polyps for food to be easily trapped.
What body type do Anthozoans lack?
medusa
Are sea fans plants or animals?
