What is Obelia?
Obelia’s common name is sea fur. It is a group of hydrozoans belonging to the phylum Cnidaria, including jellyfish, corals, and sea anemones. These aquatic animals, except the Poles, are found in marine and freshwater environments worldwide. Obelia characteristics are that they are colonial organisms with a relatively simple diploblastic body.
Obelia under a microscope, look like a complex structure, with many small polyps connected by branching tubes. Obelia structure of body resembles sea anemones that remain attached to the substrate at the bottom, like rock or sea bed, and have tentacles that they use for feeding and reproduction. However, during the life cycle of Obelia, they also have a free-moving stage of life.
Definition of Obelia: Obelia is a sedentary marine colonial organism that sticks to seaweeds, rocks, lumber piles, and molluscan shells in shallow water.
Life Cycle of Obelia – Diagram, Structure and Classification
The life cycle of Obelia shows the alteration of generation. Obelia’s common name is sea fur. It is a group of aquatic organisms. Obelia classification shows it belongs to Class Hydrozoa and Phylum Cnidaria. Obelia are diploblastic, primitive organisms with a unique life cycle in the Animal Kingdom. The Obelia life cycle alternates between two phases, each having a different structure and function. This is called the alteration of generation. In this article, we will look into the life cycle obelia – diagram, obelia classification, characteristics, and obelia structure.
