Art forms of the deep sea, Siphonophorae Poster

Vector art drawing, from a 19th century black and white illustration by Ernst Haeckel, from "Report on the Siphonophorae, collected by the HMS Challenger during the years 1873-1876". Siphonophorae or Siphonophora, the siphonophores, are an order of the Hydrozoa, a class of marine invertebrates belonging to the phylum Cnidaria. They are colonial, but the colonies can superficially resemble jellyfish; although they appear to be a single organism, each specimen is actually a colony of Siphonophora. The best known species is the dangerous Portuguese Man o' War (Physalia physalis). With a body length of 40–50 m, another species of siphonophore, Praya dubia, is one of the longest animals in the world. Colors of this work: purple, lilac, mustard and light yellow.
