Stuff in My Office

Dr Warhol’s Periodic Table of Microbes

By now you know that I like old stuff and my office is filled with it.

This series of posts will be from Ernst Haeckel’s book Kunstformen der Natur in German, which means Art Forms of Nature in English. Take a good look, this artwork was published in 1904! Haeckel lived from 1834 to 1919.  This illustration is plate 49 the Actiniae or anemone.

Sea anemones are a group of water-dwelling, predatory animals of the order Actiniaria. There are more than 1,000 species of sea anemones found throughout the world’s oceans, many attached to rocks on the seafloor. Their bodies are composed of an adhesive pedal disk, a cylindrical body, and an array of tentacles. The tentacles are triggered by the slightest touch, firing a harpoon-like filament into their victim and injecting a paralyzing neurotoxin. 

Estefanía Rodríguez, Associate Curator of Invertebrate Zoology at the American Museum of Natural History is studying the fascinating varieties of anemones and other sea life in Antarctica. In 2014, Dr. Rodríguez discovered a giant anemone-like creature with tentacles reaching more than 6.5 feet long that actually belongs to an entirely new order of animals, demonstrating there is still much to be learned about polar marine life!

See anemones, penguins, and seals in Beneath the Ice, and immersive dome installation now on view in the Milstein Hall of Ocean Life, running through May 27.

Strawberry Anemone (Actinia fragacea)

…a species of Actiniid sea anemone which is found in the northeastern and eastern Atlantic Ocean. Its range extends from Norway, Scotland and Ireland to the Mediterranean Sea and North Africa, including the Azores, the Canary Islands and Cape Verde. Strawberry anemones typically inhabit the intertidal and sublittoral zone at depths less than 10 meters (33 ft). They are generally found attached to rocks and boulders.
