L'sea ​​anemone, belonging to the order Actiniaria, is not the only anemone we encounter in nature, with the same name there is also the flower, a beautiful flower. One, marine, and the other not, these two anemones in common they have beauty and color, the flamboyant style that makes them recognizable and makes them remain etched in our minds.

Sea anemone

The sea one is one very colorful creature, close relative of coral and jellyfish. It is always, or almost always, attached to rocks, it is to all intents and purposes a stinging polyp that frequents seabed, can also live near coral reefs, his days pass waiting for a fish to pass so close that it can be grabbed.

The marine anemones they consist of a cylindrical body with a crown of tentacles in the center which are very sensitive. If you just touch them, they release, or rather, they shoot one sort of poisonous dart harpoon-shaped by injecting a paralyzing neurotoxin into the hapless victim.

Despite being colorful, they are not a pleasant encounter at sea, there are over 1,000 species, not all of them live at the same depth which, for each of them, can vary between 1.25 centimeters and almost 2 meters. In some cases, only for some varieties of anemones, there are cases of symbiosis with the green algae. Another marine creature that has interesting symbioses is theHermit crab Bernardo

Sea anemone: nutrition

Sea anemones feed on small fish and other invertebrate organisms that they capture thanks to nematocysts located on the tentacles.

How the sea anemone reproduces

There reproduction of the sea anemone takes place in two possible ways in relation to the variety of the organism.

In most cases, the sea anemone is a unisexual species and fertilization occurs with the transport of spermatozoa to the ovigerous cavities in the water. The larvae remain in the mother's body until they reach maturity such that they can become independent. At that moment they are expelled from the mother's mouth and begin their adult life.

In the hermaphroditic species of actinia, such as Cerianthus membranaceus, reproduction takes place in an asexual way, by splitting.

Anemone: flower

Let's move on to the plants that bear the name of anemone: they belong to the ranunculaceae family and they can come from South Africa or South America. Their name recalls the idea of ​​"wind flower", explained by the fact that it has very fragile corollas gaudy but which, with the wind, are easily damaged. Even the leaves, scattered and not very consistent, are at the mercy of the wind.

That the flowers are white, pink, yellow, blue or red, they are weakly poisonous due to the presence of protoanemonin, a substance that irritates the mucous membranes and skin. We must be careful ourselves and keep pets and the pets away as well livestock as long as the flower is fresh, if it is dried, then it no longer has this effect.

Anemone japonica

There japonica variety blooms between summer and autumn and is very decorative, it even reaches a meter in height and produces large flowers that open in succession. Some plants may have a double flower, others instead semi-double or simple, such as colors can be found white, pink or red. To make sure that this anemone blooms at its best and lasts a long time, let's keep it in shaded and protected places without ever running out of water or overdoing it.

Coronary anemone

This species is often used to get cut flowers, is one of the most rustic, resists the cold well and produces single or double flowers in great abundance. They can be white, but also red, blue and even purple, flanked by deep green leaves.

Among other types of anemone we find the Fulgens, with its bright red flowers, and the Nemorosa, used in herbal medicine and homeopathy for the treatment of depression, cystitis, some gastric or sleep disorders.

Wild anemone

In addition to the flower, we combine the wild anemone with an excellent scented cream that has a strong toning effect, to try for 17 euros on Amazon. In the meantime, let's delve into the legendary side of this flower named after a nymph of Flora's court.

The myth tells that Zeffiro and Borea fell in love with her, but Flora angry and jealous of Anemone, he decided to punish it by transforming it into a flower destined to open prematurely under the power of the north winds. They mercilessly they shake it and scatter its petals in the air which, in spring, already have a withered air.
