Hi Hive account@colombo1845 it is very good information that you present and very accurate, mostly these are of the species that someone would not know if they observed it in the water, but it is always a good idea to keep us informed of what they can cause us in case of contact. We invite you to share the sources of information and also the source of the images because it is very valuable information, we hope to see you back soon!😁🐬
