19th century biologist and artist Ernst Haeckel is well know for his keenness on jellyfish. He created a number of exquisite illustrations to his "Kunstformen der Natur" that show many variations of these marine animals. Some of the jellyfish included in the book were first discovered and also named by Haeckel. That is the case for Dismonema Annasethe - a species he named after his late wife Anna Sethe.
Ernst and his first cousin Anna were happily married for 18 months when she suddenly fell ill, some historians suggest it was appendicitis, and died leaving Haeckel wounded for the duration of his life.
A modern day zoologist and sea life photographer Alexander Semenov takes amazing images of Jellyfish that bare a striking resemblance to Desmonema Annasethe. Being in charge of all WSBS (White Sea Biological Station) underwater projects, he never misses an opportunity to dive with his camera.
