First experience with a Nemertine🧠 / Primera experiencia con un nemertinos🧫🔬
Hello science lovers, today we are going to see a specimen of Nemertea, they are practically "worms" that although the majority are from salt water, this one here I captured from fresh stagnant water, my first experience with these animals is that they are very difficult to identify so much that I had to ask a friend who was an expert on the subject for help, I was confused with a flatworm but no! It is a nemertea and we are going to see the main characteristics of them, which seem to have a somewhat complex anatomy!🙇♂️🧠🧫
Hola amantes de la ciencia, hoy vamos a ver un ejemplar de Nemertea practicamente son "gusanos" que aunque la mayoria son de agua salada este de aqui lo capture de una agua estancada dulce, mi primera experiencia con estos animales es que son muy dificil de identificar tanto que tuve que solicitar ayuda a un amigo experto en el tema, estaba confundido con un platelminto pero no! se trata de un nemertea y vamos a ver las principales caracteristicas de ellos que parecen tener una anatomia algo compleja!🕵️♀️👨🏫🌏🔬
Description🙇♂️🔬/ Descripcion🧠🧫
As you can see, the water feature was full of detritus and mud which is a favorable environment to find Nemerteas, they are free-living and common in salt water, however there are some species in Portugal! I am not a specialist in them so identifying the species is very complicated! Since they do not have cavities, they are classified as acoelomates, they are small in size, less than 20 centimeters, this one here is not an adult, on the contrary, since it is juvenile, it is more difficult to identify the species. One of the characteristic features of nemerteans is the proboscis or "envaginable proboscis" that has the property of retracting and expanding! I think that this specimen, due to its proboscis, could be grouped in the "enolpla" class.🔬🌏🧠
Como puedes ver la caracteristica del agua estaba llena de detritus y lodo lo que es un ambiente favorable para encontrar Nemerteas, son de vida libre y comunes de agua salada, sin embargo hay algunas especies en Portugal! no soy especialista en ellas asi que identificar la especie es algo muy complicado! como no tienen cavidades entonces son catalogados como acelomados, son de tamaño pequeño menos de 20 centimetros este de aqui no es un adulto por el contrario al ser juvenil es mas dificil identificar la especie, uno de los rasgo caracteristicos de los nemerteas es la proboscide o "trompa envaginable" que tiene la propiedad de retraerse y expandirse! creo que este ejemplar por su proboscide podria agruparse en la clase "enolpla"🙇♂️👨🏫🧫

So far, more than 1,200 species have been identified on the planet. One of the differences with flatworms is that the body wall has a more complex organization. In the upper part, they have musculature and their body is covered by cilia. The dermis is very dense. and secretes a substance in addition to having connective tissue!🧠🕵️♀️🙇♂️
Hasta ahora se han identificado mas de 1200 especies en el planeta, una de las diferencias con los platelmintos es la pared del cuerpo tienen una organizacion mas compleja en la parte superior tienen una musculatura y su cuerpo esta cubierto por cilios, la dermis es muy densa y secreta una sustancia ademas de poseer tejido conectivo!🧠🧫

Nervous system🙇♂️🔬/ Sistema nervioso🧠🧫
For these photos I used filters that allow the different types of organs to be highlighted, the nervous system is simple, made up of the ganglia that you can see in the red photo, there are four ganglia in total, as you can see on each side of the body there are two cords nerves that are distributed vertically throughout the body, the eyes can be from two to more than one hundred, they are photoreceptors and move towards light, I think this species has six.🧠🙇♂️🕵️♀️
Para estas fotos utilice filtros que permite resaltar los diferentes tipos de organos, el sistema nervioso es simple compuesto por los ganglios que puedes ver en la foto de color rojo, son cuatro ganglios en total, como puedes ver de cada lado del cuerpo hay dos cordones nerviosos que se distribuyen de forma vertical por todo el cuerpo, los ojos pueden ser desde dos a mas de cien, son fotorreceptores y se mueven hacia la luz, esta especie creo que tiene seis.🌏🔬🧫

The circulatory system is closed and two veins pass next to the digestive tube, the way the blood flows is inverted and they have inside (amebocytes) and some pigments whose function is not known to this day!🕵️♀️🙇♂️
El sistema circulatorio es cerrado y pasan dos venas al lado del tubo digestivo, la forma como fluye la sangre es de forma invertida y tienen dentro (amebocitos) y algunos pigmentos que hasta el dia de hoy no se sabe la funcion de ellos!🕵️♀️
The digestive system is nothing more than a mouth, a digestive tube included in the esophagus and anus, the excretion of substances is done by the protonephridia that are identical to flatworms, the proboscis plays an important role in the ecology of the animal since it is used For food, they are carnivores and capture their prey with the proboscis, some use a stylet that poisons the prey and then it is captured! They are dioecious, meaning their reproduction is sexual, they are common in ponds or humid areas!🔬🌏🧠
el sistema digestivo no es mas que una boca, un tubo digestivo comprendido en esofago y ano, la excresion de sustancias se hacen por los protonefridios que son identicos a los platelmintos, la proboscide hace un roll importante en la ecologia del animal ya que es usada para la alimentacion, son carnivoros y capturan sus presas con la proboscide, algunos emplean un estilete que envenena a la presa y luego es es capturada! son dioicos osea su reproduccion es sexual, son comunes de charcas, o zonas humedas!👨🏫🧠🔬
