Sertularia is a noun that refers to a type of colonial marine hydrozoans that belong to the family Sertulariidae. These organisms are commonly found in marine environments, particularly in shallow waters and rocky coastlines.
The term "sertularia" is often used to describe a genus of small, delicate aquatic animals characterized by their branched and symmetrical colony structure. The colonies of sertularia are made up of numerous individual polyps, each with a tubular body and a crown of tentacles surrounding a central mouth. These polyps are interconnected by a network of flexible stems or branches, creating a complex and beautiful colony structure.
Sertularia colonies are typically anchored to rocks or other substrates by a basal attachment called a hydrorhiza. The individual polyps within the colony work cooperatively to capture and consume small planktonic organisms by using their tentacles to create water currents that bring food particles towards their mouths.
The physical appearance of sertularia specimens can vary, with some colonies displaying vibrant colors and intricate patterns. They are often admired for their delicate beauty and are frequently observed by divers and marine enthusiasts.
Overall, sertularia is a collective term used to describe a diverse group of colonial marine hydrozoans characterized by their unique colony structure, delicate appearance, and ability to create water currents to capture food particles.
A genus of hydroid polypes, so called from their cells being arranged on the opposite sides of a fleshy or horny axis, which gives to their stems a wreath-like appearance.

The word "sertularia" comes from the Latin term "sertula", which means "little wreath" or "crown". In biology, "sertularia" is used to refer to a genus of branching colonial hydroids, marine invertebrates belonging to the class Hydrozoa. These organisms typically have a crown-like arrangement of polyps on their branches, similar to a wreath, which inspired the name.
