In the last publication of amazing nature I talked about a snail a little exotic, today I will talk about a really fascinating animal of the ocean which could go unnoticed by resembling more an aquatic plant than a dangerous and poisonous animal, I'm talking about the sea anemone accompany me to know its main characteristics.
The sea anemones are family of the whims that at the same time are related with the living formation of the corals, its scientific name is actiníaria, if phase of polyp allows it to be stationary.
These invertebrate families of jellyfish have a cylindrical body as species of branches that are anchored to corals or sea sand, and can remain attached thanks to its pedal disc system. The most amazing of its characteristics is that it has only one entrance and exit orifice, which means that through that same orifice they feed and defecate, the oral disc is provided with several tentacles with many rings.
The configuration of your organism is a little common within the world of invertebrates as for example it has only one organ if it can be called an organ, which is responsible for boosting the blood and taking care of the breathing of the anemone.
Your primitive nervous system is decentralized independently takes care of functions such as perceiving physical-chemical stimuli from your environment which helps you get food as well as maintain homeostasis.
This kind of organism similar to a vegetable is more poisonous than you imagine, have specialized cells with urticant properties, which is housed in their tentacles, the poison can only become lethal thanks to some neurotoxins that are responsible for paralyzing any animal just by rubbing it.
The sea anemones have a kind of symbiosis with the clown fish that lives among this animal that is present in all the oceans and seas of the world, especially in the Atlantic Ocean and Caribbean Sea.
There are several species of anemones and they all develop very diverse customs and qualities except what has to do with poison, the determining factor for its development is the solar radiation so it is easier to find anemones in coral barriers, shallow water.
It has a close relationship with the clown fish, this is because both have evolved over all the clown fish that is immune to the powerful poison, the main idea of the clown fish is to take refuge among the tentacles of the anemone only by its poison, a predator could see for hours a clown fish among the tentacles of an anemone if even approach due to the risk that would run by its poison.
Anemones feed mainly on small mollusks and some fish offspring.
As for its reproduction we can say that it is asexual and sometimes sexual, it all depends if it develops as a gemation or binary fission, other times it can be by pedal laceration which means that part of its body is divided to give life to another sea anemone.
Sexual reproduction is carried out by the male who releases the sperm in the environment in which he lives, preparing the reproductive system of females, then the female is excited, releases the egg to be fertilized.
Although the anemones seem fragile and delicate in their habitat, many hunters capture them to be taken to an aquarium, it is common that they sell the anemones with clownfish.
