Zoanthus, commonly known as "zoas" or "button polyps," are a genus of colonial, polyp-forming anthozoans, related to sea anemones. They are popular in the aquarium hobby due to their vibrant colors and relatively easy care. Zoanthids are characterized by their encrusting growth form, spreading across surfaces like a mat, with individual polyps connected by a fleshy tissue called a coenenchyme.
Here's a more detailed description:
-
Colonial Structure:
Zoanthus colonies are made up of numerous individual polyps, each with a central mouth surrounded by tentacles. These polyps are connected by a mat-like structure called the coenenchyme, allowing for nutrient and energy transfer throughout the colony.
-
Growth Form:
Zoanthids typically grow in a flat, encrusting pattern, often resembling a carpet or mat on rocks, sand, or other surfaces.
-
Appearance:
They exhibit a wide range of colors and patterns, with many hobbyists naming specific color morphs (e.g., "Watermelon," "Miami Vice"). Some zoanthids also possess proteins that cause them to fluoresce under certain lighting conditions.
-
Habitat:
Zoanthids are commonly found in coral reefs, where they can tolerate a wide range of light and water flow conditions. They are often found in shallow, high-light environments, but some species can also be found in deeper waters.
-
Aquarium Care:
Zoanthids are generally considered relatively easy to care for in captivity, making them a popular choice for reef aquariums.
-
Toxicity:
It's important to note that some zoanthids contain palytoxin, a potent toxin that can be harmful if ingested or if it comes into contact with skin or eyes. Some aquarium hobbyist sites say to handle them with care and avoid contact with the toxin.
