Gallery
The magnificent sea anemone (Heteractis magnifica) is a marine creature, found in the tropical waters of the world. Previously known as the Ritteri anemone, they reside alongside corals and host clownfish and algae under their tentacles, forming a symbiotic relationship.
Having a bulbous head and a body of tentacles, they do not have any other organs like eyes, ears, nose, or limbs. Their mouth serves the dual purpose of ingesting food and excreting wastes.
Although not fast movers, they move around hard surfaces with their sticky feet, present beneath their tentacles.
They are found both in deep and shallow waters and attached to the reef. Having a carnivorous diet, they predate their prey releasing toxic chemicals from their bodies.
These anemones are a very popular pet species, capable of surviving well in aquariums. But it requires proper diet and care to adapt and coexist with other fishes in the artificially created environment.
