Hello science addicts! Today I am very happy because for the first time I observed two species that I had never seen under a microscope and they are very fantastic! it is a Nemertea and a Macrostomum both have that appearance of being "worms" but they are not! they actually belong to a unique phylum of them! and to have more luck with my capture I was able to photograph a species where we can see eggs. Join me in this experience.🕵️♂️🧠
Hola adictos a la ciencia! hoy estoy muy contento porque por primera vez observe dos especies que nunca habia visto en el microscopio y son muy fantasticas! se trata de un Nemertea y un Macrostomum
ambos tienen aquella apareciencia de ser "lombrices" pero no lo son! en realidad pertenecen a un filum unico de ellos! y para tener mas suerte con mi captura logre fotografiar una especie donde podemos ver huevos. Acompañame en esta experiencia.🌍👨🏫👨🎓🕵️♂️
About the Nemertea🙇♂️🕵️♀️/Nemertea🔬🧠
This phylum is known for presenting "acelomate" worms that do not have segments like earthworms for example! In the video you can see their morphological characteristics, they are flattened and elongated animals, their main characteristic is that they have an "evaginable" "proboscis", they are not very big and they are not small either, they measure on average about 20 centimeters, however there is a species that can reach grow about 50 centimeters in length!🤔🧠🔬
Este filo es conocido por presentar gusanos "acelomados" que no poseen segmentos como las lombrises de tierra por ejemplo! en el video puedes observar su caracteristica morfologica son animales aplanados y alargados su principal caracteristica es que presentan una "proboscide" "evaginable"no son muy grandes y tampoco pequeños, miden en promedio unos 20 centimetros sin embargo hay una especie que puede llegar a crecer unos 50 centimetros de largura!🕵️♀️👨🏫
They are free-living animals that are mostly found in salt water, those that inhabit fresh water are very specific, I managed to grow it on the edge of my aquarium where sediments are still stored to feed themselves, scientists still cannot affirm with total credibility that they are cosmopolitan and we can get them all over the world because there is no concrete record about that! For example, in Australia there is only one species and in the United States it is quite difficult to see them!🔬🕵️♀️
Son animales de vida libre que en su mayoria son encontrados en agua salada, los que habitan las aguas dulces son muy especificos, yo lo logre cultivar en la orilla de mi acuario donde aun se almacenan sedimentos para el poder alimentarse, los cientificos aun no pueden afirmar con total credibilidad que son cosmopolitas y podemos conseguirlos en todo el mundo porque no hay un registro concreto sobre eso! por ejemplo en australia solo existe una especie y en estados unidos es bastante dificil de verlos!👨🎓🕵️♂️🌍😮
Anatomy🙇♂️🕵️♀️/Anatomia🔬🧠
The surface of their body is covered by "cilia" an interesting characteristic of the epidermis of these animals is that it "excretes a substance", they have a nervous system with "four ganglia and a brain", as you could see in the video and photos They have 4 eyes but there are species that can have hundreds of them "are photoreceptors" and capture external light stimuli! We also note that the cilia in the epidermis have a chemical function.🕵️♀️🔬
La superficie de su cuerpo esta cubierta por "cilios" una caracteristica interesante de la epidermis de estos animales es que "excreta una sustancia", tienen un sistema nervioso con "cuatro ganglios y un cerebro", como pudistes ver en el video y las fotos tienen 4 ojos pero hay especies que pueden tener ciento de ellos "son fotoreceptores" y captan estimulos de luz exterior! tambien destacamos que los cilios en la epidermis tiene una funcion quimica.🧠👨🏫
They have a "closed" circulatory system and run two extensions to the sides, the circulation occurs in reverse! and they have some pigments unknown to biology! They are very interesting and mysterious animals! the digestive system is tubular and complete with a mouth and anus😮🕵️♀️
Tienen un sistema circulatorio "cerrado" y corren dos extensiones a los lados, la circulacion ocurre de forma inversa! y tienen unos pigmentos desconocidos para la biologia! son animales muy interesantes y misteriosos! el sistema digestivo es tubular y completo con boca y ano🧠🔬🕵️♀️
Prostoma graecense🙇♂️🕵️♀️🔬🧠
With the help of my Biologist friends I was able to identify the species, it is Prostoma graecense, this species is classified as cosmopolitan and is distributed all over the world! They are hermaphrodites, the species has between "2-3 pairs of eyes", it is believed that it was introduced by man and that is why it is found all over the planet! The most interesting season to study them is in the fall, they are freshwater and difficult to see in the United States!🧠😮
Con ayuda de mis amigos Biologos pude identificar la especie, se trata de Prostoma graecense esta especie es clasificada como cosmopolita y se distribuye al rededor de todo el mundo! son hermafroditas, la especie posee entre "2-3 pares de ojos", se cree que fue introducida por el hombre y es por eso que se encuentra en todo el planeta! la temporada mas interesante para estudiarlos es en otoño, son de agua dulce y dificil de verlos en estados unidos!👨🏫🌍
🙇♂️🕵️♀️Macrostomum🔬🧠
Another species that I photographed for the first time, it is the Macrostomum, a species of flatworms that are also distributed throughout the world, and that are hermaphrodites, free-living and their distinctive characteristic is that they have a stylet that they use to prick the female to introduce his sperm and release it afterwards! The explanation for this is that from time to time they like to exchange genetic material! They are very small, barely reaching 5mm.😮🧠🕵️♀️
Otra especie que fotografie por primera vez, se trata del Macrostomum una especie de platelmintos que tambien se distribuyen por todo el mundo, y que son hermafroditas, de vida libre y su caracteristica distintiva es que tienen un estilete que utilizan para pinchar a la hembra introducir su esperma y soltarla posteriormente! la explicacion a esto es que les gusta de vez en cuando intercambiar material genetico! son muy pequeños apenas llegando a los 5mm.🕵️♀️🌍👨🏫🔬
They are transparent and the smaller species have an oval appearance! their name is derived from "big mouth" and is that some species have a mouth almost the size of the animal", are species that normally feed on algae, and sometimes benthic invertebrates! in fresh water they live in algae or in sediments.🌍🔬
Son transparentes y las especies de menor tamaño tienen un aspecto ovalado! su nombre es derivado de "boca grande" y es que algunas especies tienen una boca de casi el tamaño del animal", son especies que normalmente se alimentan de algas, y algunas veces invertebrados bentonicos! en el agua dulce viven en las algas o en sedimentos.🕵️♂️🧠
