Hello @animal-life, I loved your article and this is because I am passionate about life under the seabed, some time ago I published an article dedicated to jellyfish and some of its types, because as you say there are many, the bottom of the Sea is an immense universe where there is still a lot to explore because this is that every day we are surprised with the different species that are discovered in it, I invite you to visit my blog and I regularly publish articles on this subject that I love, I have several dedicated to life deep in the oceans, which I am sure will be of your interest, a greeting and we are in contact!
