What color is anemone?


Its body is composed of an adhesive pedunculate disc, or foot, a cylindrical body and a series of tentacles surrounding a central mouth. The tentacles shoot out at the slightest touch, spearing the victim with a harpoon-like filament that injects a paralyzing neurotoxin. The tentacles then carry the helpless prey into the mouth.

They also have a more famous symbiotic alliance with the clownfish, which is protected by a mucous layer that makes it immune to the anemone’s sting. The clownfish lives among the tentacles of the anemone, protecting itself from predators, and the anemone takes advantage of the clownfish’s leftover food.

Sea anemone characteristics

here it is practically impossible to bury oneself on the bottom and, while shrimps and other mobile crustaceans can escape from the danger zone during the ebb of the waters, looking for cracks in the rocks or pools of water during low tide, sessile species, such as algae, molluscs, anemones or balans, have to resort to other survival strategies. alternative-solution.net

On the west drop-off, in addition to the beautiful soft corals and black trees, there is a huge colony of sea anemones with their clownfish located at shallow depths, where it is very pleasant to go snorkeling. redsea-direct.com

If you go into Exmouth Beach or Coral Bay you will see clownfish swimming among anemone tentacles, lionfish and predatory moray eels, as well as hundreds of other fish species.


Sea Anemone. It looks like a colorful plant and not an animal. Some are attached to the sandy bottom but most, as is the case of actinias, are anchored to more solid supports, such as rocks. They can reach up to 7 cm in height.

It has a thick spine that widens towards the oral disc and carries 70-384 long, flexible tentacles, gradually decreasing in thickness. The base of the spine is up to 7 cm wide and the tentacles span 20 cm, specimens living in deeper water are larger. They reach a height of 8 cm.

They are found in the Atlantic Ocean and in the Mediterranean Sea as the yellow encrusting anemone. Anemones are much easier to keep than corals, although many of the more popular anemones share with many corals the possession of algal hosts and require good lighting to thrive.

Prey is captured and paralyzed by means of tentacles with nettle cells and transported to the mouth with cilia. Undigested waste is regurgitated and excreted through the mouth. They can also reabsorb the decomposition products of bacteria living in their digestive cavity.

Sea anemones

Clownfish protect themselves from predators by sheltering between the tentacles of anemones, and each month they lay eggs at their base. Similarly, anemones are also protected by the clownfish they host.

A team of researchers and students visited, every day from October 2015 to December 2016, a total of 13 pairs of clownfish and their host anemones on the coral reefs of the island of Moorea (French Polynesia).

Blood samples taken from 52 pairs of clownfish (including the 13 previously mentioned) showed a sharp rise in the level of cortisol, the stress hormone, and a significant drop in sex hormone concentrations (the equivalents of testosterone and estrogen). The bleaching of anemones due to increased sea surface temperature is therefore a stress factor that reduces the levels of sex hormones and, with it, the fertility of the fish. These links have been found for the first time in the natural environment in which the fish live.
