Friday, November 7th 2025
The common sea fan
The common sea fan, is a type of soft coral found in the warm, shallow waters of the Caribbean and the western Atlantic ocean. It grows in wide, fan-shaped forms that sway gently with the ocean currents, helping it catch tiny food particles drifting by. Its beautiful purple branches are covered by a thin living tissue that hosts tiny algae, which provide much of the coral's energy through sunlight.
