Hi Aquatic Sentinels!🐬
Once again, I bring you content that I consider to be of quality, this takes several hours of reading, comprehension and writing.💡📚
But more than that, this is one more publication so that together we can appreciate and contemplate how wonderful our ocean is!

A few days ago @actioncats shared with us super important information about international whale shark day😄 (you can read it here👉: https://peakd.com/hive-154473/@actioncats/dia-internacional-del-tiburon-ballena-international-whale-shark-day-espeng), which is undoubtedly a majestic animal due to its peculiarities and large size. It makes us happy to know that there are such incredible beings as this species, but we rarely think about how we harm them, the short answer is: through polluting substances.😷

Whale shark (Rhincodon typus)
Previously @actioncats already told us about biology and other issues, an excellent post!👌 But it is always good to return to enrich the information and give a "cover letter".
Stevens (2007) describes this species as follows: The largest fish on the planet, it is distributed in the oceans around the world and reaches between 18 and 20 m in total length. It lives in areas close to the sea surface (epipelagic) and near the coast (neritic) in tropical and subtropical regions, between 30º N and 35º S, where it prefers waters with temperatures of 26.8 ° C and 30.2 ° C (28 ° C on average) and salinities between 34.5 ‰ and 35.5 ‰.

Rhincondon typus was first described in 1828 by Andrew Smith using a 4.6 m specimen in South Africa. An interesting fact is that from this year until the 80s it was mainly observed in captures, strandings and sightings, the latter made during the shark feeding. Because diving began to become more popular in 1990, whale shark aggregations began to be discovered around the world, which promoted ecotourism and increased scientific research on this species.
Pollutants reduce whale shark populations😓
Pollution in the marine environment has become a global problem due to increasing levels of toxic substances and their impacts on biota and human health. Although these substances can reach the sea naturally such as through erosion, rock erosion, volcanic eruptions and hydrothermal vents, they can also come from human sources such as mining, industry, incineration, agriculture and aquaculture.

Some substances can be extremely toxic to living beings due to their persistence and ability to accumulate in the food or trophic web...
So we not only damage our ecosystems, but even ourselves, since in the end we consume these marine resources, affecting the pH, water quality and salinity.
Trace elements (TE)☣️
When we refer to polluting substances in the marine environment, we refer to trace elements or trace elements (which we will call "TE"). These elements are persistent in the environment and are found in low concentrations (parts per million), are potentially reactive and can bioaccumulate in the food web. Some of these substances can be mercury, lead and cadmium are the most polluting elements in the environment (Páez-Osuna et al. 2017).

Regardless of the sources of these pollutants, the final receptors are the atmosphere, the aquatic ecosystem, and biota, so their use must be carefully regulated.
The situation of whale sharks
Studies have been carried out in some parts of the world such as Mexico and the Gulf of California, and high levels of toxic substances have been found in the muscle and epidermis of these animals, this situation could put the specimens in critical danger.

Wonderful publication that touches more in depth everything related to what is affecting these wonderful fish, your images fascinated me, thanks for the mention and for this information that complements in a great way what is already exposed, I hope we can sensitize many with this information, on Tuesday I will have a special program about the Whale Shark in the Discord server of @laradio https://discord.gg/ at 4:00 pm Venezuelan time, you are cordially invited @juanbg
Hola @actioncats! Creo que he visto tu comentario muy tarde😢 me encantaría estar ahí, y también si así lo deseas puedo compartir en su servidor de Discord algún tema sobre la fauna marina, con mucho gusto lo haría!😁🐬
no importa que no hayas asistido @juanbg, pero me alegra tu disposición para educar y dar a conocer estos temas tan importantes, tengo ideas en mente búscame en Discord Cristinanuitter(actioncats)#7170 y allí vemos que acordamos.
Excelente, te buscaré!😁🐬
