Hannah Waters

One of Hannah Waters's earliest memories is digging up sand crabs on a Delaware beach, and she hasn't stopped digging the ocean. Formerly a writer, editor and producer for the Ocean Portal at the Smithsonian National Museum of Natural History, she is currently an associate web editor at Audubon.org. She studied Biology and Latin Minnesota’s Carleton College, sneaking off to the coasts in the summertime to study seabird colonies, conserve endangered piping plovers, and help lobstermen with their traps. She loves cephalopods, imagining plankton as larger-than-life monsters, and weird adaptations.

Purple Sea Urchin

This purple urchin Paleopneustes cristatus is seldom seen by itself, and can be found in groups of hundreds. Dr. Dave Pawson , a senior scientist at NMNH who studies deep-sea echinoderms, is testing if the fertilized eggs of...

Little Sea Star

It’s an honor to have something or someone named after you. Dr. David Pawson , Senior Research Scientist and Curator of Echinoderms at NMNH, has several genera and species, living and fossil, named after him. He says this...

Deploying ARMS in the Deep Reef

Deploying ARMS (Autonomous Reef Monitoring Structures) is tricky in the deep sea, where SCUBA divers can't place and secure them to the floor with their hands and a hammer. Researchers with DROP (Deep Reef Observation...

ARMS Deployment from a Submarine

Submarine pilot Bruce Brandt secures ARMS (Autonomous Reef Monitoring Structures) to the submersible Curasub off the coast of Curacao. In shallow water, SCUBA divers can place these biodiversity-measuring structures on the...

Marine Zooplankton

The Census of Marine Zooplankton (CMarZ), a project of the Census of Marine Life, aimed to identify and study the biodiversity of animal plankton around the world, including ~6,800 described species in fifteen phyla. The...

The Squidworm - A New Species

In the Coral Triangle, a biodiverse area between Indonesia and the Philippines, scientists discovered this swimming polychaete (bristly worm), which they have dubbed the "squidworm." Using a remotely operated vehicle, the...

Deep Sea Copepod

This copepod ( Gaussia princeps ) was collected deeper than 1000 meters in the Sargasso Sea by Census of Marine Zooplankton (CMarZ) researchers in April 2006, as part of the 10-year Census of Marine Life . However, specimens...

Zooplankton Biodiversity

Holozooplankton are animals that live adrift in the ocean waves for their entire lives. The researchers who took part in the Census of Marine Zooplankton, a project of the Census of Marine Life , spent a decade surveying and...

Jellyfish, or Siphonophore Colony?

This colony of Rosacea may look like a single jellyfish, but it is actually a large group of smaller siphonophores clustered and living together. In fact, the zooids (individual siphonophores living in the colony) cannot...

A Ctenophore Feeds

The comb jelly (ctenophore) Thalassocalyce inconstans is found in shallow to deep water in the Atlantic Ocean, Mediterranean Sea, and sometimes in warmer Pacific Ocean waters off the coast of California -- although this one...
