Scolanthus
Scolanthus is a genus of colonial, anemone-like corals in the family Xeniidae. They are commonly called “soft corals” because their skeletons are not composed of hard calcium carbonate like other corals. Instead, they have a flexible, protein-based structure that allows them to move and sway with the currents.
Common Names
Members of the Scolanthus genus are commonly known as "tree corals" or "finger corals" due to their branching, tree-like growth habit.
Characteristics
Scolanthus corals are characterized by their:
- Colonial nature: They form colonies of interconnected polyps, each with a central mouth surrounded by tentacles.
- Branching growth: They grow in a branching, tree-like pattern, creating intricate formations.
- Soft, flexible skeleton: Their skeleton is composed of protein and is not hard like that of stony corals.
- Variety of colors: They can come in a wide range of colors, including green, brown, orange, and purple.
- Symbiotic relationship with zooxanthellae: Like many other corals, they harbor symbiotic algae (zooxanthellae) within their tissues, which provide them with energy through photosynthesis.
Environments
Scolanthus corals are found in tropical and subtropical waters worldwide, typically in shallow, clear waters with strong currents. They prefer habitats with ample sunlight to support their symbiotic algae.
