Sea Pen
Sea pens are marine cnidarians belonging to the superfamily Pennatuloidea, which are colony-forming benthic filter feeders within the order Scleralcyonacea. There are 14 families within the order and 35 extant genera, and it is estimated as of 2011 that, of 450 described species, around 200 are valid. Sea pens have a cosmopolitan distribution, being found in tropical and temperate waters worldwide, from intertidal shallow waters to deep seas of more than . The earliest accepted sea pen fossils are known from the Cambrian-aged Burgess Shale ('' Thaumaptilon''). Similar fossils from the Ediacaran may show the dawn of sea pens. Precisely what these early fossils are, however, is not decided. Taxonomy The superfamily Pennatulacea consists of the following families: * Anthoptilidae * Balticinidae * Chunellidae * Echinoptilidae * Funiculinidae * Gyrophyllidae * Kophobelemnidae * Pennatulidae * Protoptilidae * Pseudumbelludlidae * Renillidae * Scleroptilidae ...

Ptilosarcus Gurneyi
''Ptilosarcus gurneyi'', the orange sea pen or fleshy sea pen, is a species of sea pen in the family Pennatulidae. It is native to the northeastern Pacific Ocean where it lives in deep water anchored by its base in sand or mud. It has received its common name because of its resemblance to a quill in a bottle of ink. Description The orange sea pen is a colonial cnidarian, the individual polyps having their own specialised functions. One, the primary polyp, loses its tentacles and forms both the stalk of the colony (known as the rachis), and the bulbous base with which it anchors itself deep into the soft substrate. Other polyps are known as secondary polyps. They include autozooids, which are feeding polyps, being armed with cnidocytes on the eight branching tentacles which form the feathery branches of the sea pen. They also contain the gonads. Other secondary polyps are siphonozooids, which can force water into and out of the colony to ventilate it. When the colony is disturbe ...

Christian Gottfried Ehrenberg
Christian Gottfried Ehrenberg (19 April 1795 – 27 June 1876) was a German Natural history, naturalist, zoologist, Botany, botanist, comparative anatomist, geologist, and microscopy, microscopist. He is considered to be one of the most famous and productive scientists of his time. Early collections The son of a judge, Christian Gottfried Ehrenberg was born in Delitzsch, near Leipzig. He first studied theology at the University of Leipzig, then medicine and natural sciences in Humboldt University of Berlin, Berlin and became a friend of the famous List of explorers, explorer Alexander von Humboldt. In 1818, he completed his doctoral dissertation on fungi, ''Sylvae mycologicae Berolinenses.'' In 1820–1825, on a scientific expedition to the Middle East with his friend Wilhelm Hemprich, he collected thousands of specimens of plants and animals. He investigated parts of Egypt, the Libyan Desert, the Nile, Nile valley and the northern coasts of the Red Sea, where he made a special ...
