Why I Love Polychaetes

Credit: © 2008 K.J. Osborn Polychaete worms are not your average cringe-inducing, writhing worms. (Okay, maybe some are.) They are fascinating, varied, and a critical part of our ocean. The visual variety among the more than 10,000 described species means a polychaete enthusiast is never bored. They come in every imaginable color and pattern, from completely transparent to iridescent to candy striped. You can find polychaetes of every shape from spherical to sausage-shaped to pencil thin, and every size from microscopic to several feet long. Some are smooth and sleek, others frilly and...Read more

Shooting the Waves: Tips from a Surf Photographer

Waves play an important role in the way coastal ecosystems function, and also provide tourism dollars because of their draw for surfers. Credit: Flickr user bluewavechris A great surf photograph appears loose and improvised, like the waves and surfers it depicts. The reality is less spontaneous. The photos that you see in surf magazines rarely happen by accident, and could never be captured without preparation and planning that can start months before—all to capture a moment that lasts a fraction of a second. Hauling your bulky camera and housing through the surf is rarely easy, and staying...Read more

December in Malibu

"December in Malibu" by Andrew Richards Credit: Andrew Richards Shooting seascapes often involves hiking on very delicate rock formations near tidepools and reefs full of plant and marine life. The photographer has to be very careful when walking on these rocks, not only for his or her safety, but also to avoid disrupting the natural environment. When I first began shooting seascapes, I'd often get so focused on getting the composition and lighting just right, sometimes I would start rushing and become careless. I'd scramble across the rock formations to compose shots without always giving...Read more

Art Forms in Nature: Marine Species From Ernst Haeckel

From recent articles published via premier scientific journals to monumental volumes marking the beginning of our study of the natural world, BHL’s collections include information about species from every corner of the globe and...Read more

Break On Through

"Break On Through" was taken by Wendy Wolf at California's Pfeiffer Beach. This photo was a winning selection in the Portraits of Planet Ocean Flickr contest. Credit: Wendy Wolf I took this shot at Pfeiffer Beach, my favorite beach in my home state of California. If you aren't familiar with it, it is a very secluded beach in Big Sur where we have some of the most spectacular scenery to be found. Up until somewhat recently, Pfeiffer Beach remained a fairly well kept "secret" of area locals. If you blink an eye, you will miss the entrance to the windy road that takes you from the hairpin curves...Read more

Why the Littlest Fish Matter a Whole Lot

A tornado of sardines swirls around diver and photographer Erwin Poliakoff in the Philippines. Credit: Erwin Poliakoff Top predators along the California coast are having a rough year. Recently starving sea lions have showed up on California beaches and are clamoring for fish at the mouth of Oregon's Columbia River ; tens of thousands of dead Cassin’s Auklets have washed up on shores from Alaska to California. Although we cannot say precisely why these animals are having such a hard time finding food, we can point to a problem with their food source, forage fish. What exactly are forage fish...Read more

SCUBAnauts Splitting The Sign

Participants in the challenge must first set a compass bearing in the direction they are headed to properly navigate underwater. Credit: Courtesy SCUBAnauts International I am a member of SCUBAnauts International , an organization for young people passionately interested in the ocean. Of all my experiences as a SCUBAnaut, sharing my love of the ocean with wounded veterans really stands out. As we come up to Memorial Day, I wanted to share what this has meant for me. It was the summer of 2012, and salt water cascaded into my mouth as I emerged above the water's surface. Sputtering for a few...Read more

Bugs and Slugs: The Hidden Secret to Healthy Seagrasses

Neptune grass ( Posidonia oceanica ) is a slow-growing and long-lived seagrass native to the Mediterranean. Credit: Gaynor Rosier/Marine Photobank Slip into the water along a sheltered coast in nearly any part of the world and you’re likely to find yourself in an emerald field of seagrass . Like flowering plants on land, seagrasses grow, flower, and produce seeds—and they do it all underwater. Although they may lack the star power of coral reefs, seagrass meadows can be equally beautiful, teeming with a diversity of life, and are every bit as important as reefs. Seagrass meadows are nurseries...Read more

The Discovery of Two Extreme Sea Stars

Two new species of sea stars were discovered in the deep sea: Paulasterias tyleri (on the left) in a North Pacific hydrothermal vent community, and Paulasterias mcclaini (on the right) in the deep sea off the coast of Antarctica. Credit: Chris Mah, NMNH Recently, Smithsonian National Museum of Natural History researcher Chris Mah and collaborators with the British Antarctic Survey and the Monterey Bay Aquarium Research Institute used molecular tools and a scanning electron microscope to discover two new species of sea stars. These sea stars live across the world from one another, one in...Read more
