Ernst Haeckel Ctenophorae Jellyfish Throw Pillow

Any of various marine invertebrates of the phylum Ctenophora, having transparent or translucent gelatinous bodiesbearing eight rows of comblike cilia used for swimming. Many ctenophores are bioluminescent. Also called combjelly. Ernst Heinrich Philipp August Haeckel was a German biologist, naturalist, philosopher, physician, professor, marine biologist, and artist who discovered, described and named thousands of new species, mapped a genealogical tree relating all life forms, and coined many terms in biology, including anthropogeny, ecology, phylum, phylogeny, stem cell, and Protista. Haeckel promoted and popularized Charles Darwin's work in Germany and developed the influential but no longer widely held recapitulation theory ("ontogeny recapitulates phylogeny") claiming that an individual organism's biological development, or ontogeny, parallels and summarizes its species' evolutionary development, or phylogeny. The published artwork of Haeckel includes over 100 detailed, multi-color illustrations of animals and sea creatures (see: Kunstformen der Natur, "Art Forms of Nature"). As a philosopher, Ernst Haeckel wrote Die Welträtsel (1895–1899; in English: The Riddle of the Universe, 1901), the genesis for the term "world riddle" (Welträtsel); and Freedom in Science and Teaching to support teaching evolution.
