Euphyllia
Euphyllia is a genus of large-polyped stony corals, belonging to the family Euphylliidae. They are commonly known as “hammer corals” due to their distinctive hammer-shaped polyps. These corals are popular in the aquarium trade for their vibrant colors and unique shapes.
Characteristics
Euphyllia corals are characterized by their large, fleshy polyps that extend from the coral skeleton. They have a distinctive "hammer" or "club" shape, with numerous tentacles arranged in a radial pattern around a central mouth. The polyps can be brightly colored, ranging from green and brown to orange and red, with some species exhibiting fluorescent pigments.
These corals are known for their ability to extend their polyps significantly during feeding, giving them a "furry" appearance. Their skeletons are typically massive and branching, forming colonies that can grow quite large.
Environment
Euphyllia corals are found in tropical and subtropical waters of the Indo-Pacific region. They prefer shallow, reef environments with moderate water flow and high levels of light. They are typically found in areas with clear water and abundant food sources.
