<div class="text-justify">Hello science lovers! Today we are going to create a post dedicated to fish scales, for this I managed to collect two scales from different parts of a saltwater fish (Dicentrarchus labrax), the scales of the fish can vary depending on the family and other environmental conditions! The most interesting thing about the post will be calculating the age of a fish using the scales. Did you know about that? do not miss this interesting experience!🐟🧠📚

Hola amantes a la ciencia! hoy vamos a crear un post dedicado a las escamas de los peces, para ello logre recolectar dos escamas de diferentes partes de un pez de agua salada (Dicentrarchus labrax), las escamas de los peces puede variar dependiendo la familia y otras condiciones ambientales! lo mas interesante del post sera calcular la edad de un pez utilizando las escamas sabias de eso? no te pierdas esta interesante experiencia!🌏🥼🧫🔬</div>

<div class=pull-left>First I would like to define what a scale is before making a deeper approach: the author: "Fernandez, 2017"(1) defines a scale as: "modified integumentary bones that fish present and which in turn have the shape of small sheets". Being integumentary, they then surround the "skin" of the animal creating an "exoskeleton" that protects the fish from adverse environmental conditions and even bacteria and parasites.🔬🧫

</div><div class=pull-right>Primero me gustaria definir que es una escama antes de realizar un aborde mas profundo: el autor: "Fernandez, 2017" (1) define una escama como: "huesos modificados tegumentarios que presentan los peces y que a su vez tienen forma de pequenas laminas". Al ser tegumentarias entonces rodean la "piel" del animal creando un "Exoesqueleto" que protege al pez de condiciones ambientales adversas e inclusive bacterias y parasitos". 🐟🧑‍🏫</div>

<div class=pull-left>How to gain experience if we do not dare to risk? Previously, did you lose a drone on a cliff and was that a reason not to continue piloting it in these environments? On the contrary, I learned from my past mistake due to the thrust that the drone makes when it brakes in normal or sport mode! Now I don't repeat that because I always come back to Cinema! therefore this is how we become better trial and error pilots!🧠🌍

</div><div class=pull-right>Como adquirir experiencia si no nos atrevemos a arriesgar? anteriormente perdi un drone en un acantilado y era motivo para no continuar a pilotearlo en estos ambientes? al contrario aprendi de mi error pasado por el empuje que hace el drone cuando se frena en modo normal o sport! ahora no repito eso porque regreso siempre en Cinema! por tanto es asi como nos convertimos en mejores pilotos ensayo y error!🕵️‍♂️</div>

<div class=pull-left>When we see a scale in the microscope we immediately compare it with a human fingerprint due to its large number of lines, the scales of fish have their origin in the "mesoderm in the dermis", they do not follow a design pattern and therefore there are various shapes, colors and extension". "Fernandez, 2017 classifies the scales as: placoid, cosmoid, ganoid, cycloid and ctenoid" (1), the scales have several functions, highlighting a protective barrier for water loss and physical damage to the tissue .🧑‍🏫🐟

<div class=pull-left>"Miranda; Escala, 2002" (2) have an interesting focus on the scales and describe them as: "semi-flexible sheets that produce concentric lines and rooted striations". And the most interesting part is this description by the authors: "They are arranged in the body of the animal like roofs on the roof of a house, one superimposed on top of another" It is not the first time that I write about scales since I previously made a post about the tissues of each animal, but it is the first time that I give a deeper and more scientific approach!🧫📚🧑‍🏫

</div><div class=pull-right>"Miranda; Escala, 2002" (2) tienen un enfoque interesante sobre las escamas y las describen como: "laminas semi-flexibles que producen lineas en forma concentricas y de estrias radicadas". Y la parte mas interesante es esta descripcion de los autores: "Se disponen en el cuerpo del animal como tejados en el techo de una casa una superpuesta encima de otra" no es primera vez que escribo sobre escamas ya que anteriormente hice un post sobre los tejidos de cada animal, pero si es es primera vez que doy un enfoque mas profundo y cientifico!🧠🧑‍🏫</div>

<div class=pull-left>Defining a fish as a scaly animal is something a bit more complex than that! Because not all fish have scales, such is the example of "Anguilliformes and Myxiliformes", it was simply an "evolutionary act" of the animal to adapt to some aquatic environments, many of them produce a "slime" that allows them to flee from their prey or protect their "skin", even without scales they are considered fish! (3)🌏🐟🧠

<div class=pull-left>In reality, the structure of the scales ends up not having great variations in freshwater and saltwater fish because they fulfill the same protection function, therefore what we see in the image are scales of two species: (Esox lucius
and Dicentrarchus labrax) would you like to tell them apart? let's see...🧫🌏

*The ctenoid scales are characteristic for presenting "toothed combs", they grow according to the growth of the fish! For each year of growth, a band of rings is added!🔬🧫🧑‍🏫*

<div class=pull-left>When the rings are less thick then a slow growth occurred which is usually due to the weather, since in winter they tend to grow slower! and of course a wider ring can correspond to the summer and spring months! It is an easy method to calculate the age, however it is not very exact!🐟🧠

</div><div class=pull-right>Cuando los anillos son menos gruesos entonces ocurrio un crecimiento lento que normalmente es por el clima, ya que en invierno tienden a crecer mas lento! y claro un anillo mas ancho puede corresponder a los meses de verano y primavera! es un metodo facil para calcular la edad sin embargo no es muy exacto!🧫🧑‍🏫</div>
