Creeping slowly across the deep seafloor on long, spindly legs, giant sea spiders are found in many deep-sea areas. But, as with many deep-sea animals, we know very little about how sea spiders live. A recent paper by MBARI-affiliated researchers shows that sea spiders suck the juices out of deep-sea anemones.

After planting several dead whales on the seafloor, a team of biologists recently announced that as many as 15 different species of boneworms may live in Monterey Bay alone.

Julie Packard was presented with a plaque containing photos of a new species of deep-sea coral that was recently named after her.

A new paper shows that animal communities on the abyssal seafloor are affected in a variety of ways by climate change.

Like the robotic rovers Spirit and Opportunity, which wheeled tirelessly across the dusty surface of Mars, a new robot spent most of July traveling across the muddy ocean bottom, about 40 kilometers (25 miles) off the California coast.

Deep-sea worms have evolved an amazing array of body types and survival strategies. The latest addition to this collection of oddities is a group of swimming worms with small oval sacs of fluid hanging from their bodies, just behind their heads.

Scientists at NOAA’s National Centers for Coastal Ocean Science and MBARI have successfully conducted the first remote detection of a harmful algal species and its toxin below the ocean’s surface.

New calculations made by marine chemists from MBARI suggest that low-oxygen "dead zones" in the ocean could expand significantly over the next century.

Researchers at the Monterey Bay Aquarium Research Institute recently solved the half-century-old mystery of a fish with tubular eyes and a transparent head. Ever since the "barreleye" fish Macropinna microstoma was first described in 1939, marine biologists have known that it's tubular eyes are very good at collecting light.

Many animals (including humans) spend a great deal of time selecting and fighting to keep their mates. Octopuses, which tend to be loners, have never been shown to engage in such complicated reproductive strategies. However, a new research paper by MBARI postdoctoral fellow Christine Huffard shows that at least one type of octopus (and probably others) do engage in elaborate "mating games."

Over the last five years, large, predatory Humboldt squid have moved north from equatorial waters and invaded the sea off Central California, where they may be decimating populations of Pacific hake, an important commercial fish.

According to a new study in this week’s journal Science these floating islands of ice—some over 20 kilometers (12 miles) across—are having a major impact on the ecology and chemistry of the ocean around them.

It sounds like a junior high school riddle—"What lives 3,000 feet below the ocean surface, is about the size of a marble, and looks like the back side of a pig?" MBARI biologist Karen Osborn and her colleagues recently came up with an answer to this riddle by combining modern DNA analysis with traditional methods of scientific observation.

On September 17, 2006, researchers from NOAA's National Marine Sanctuary program and MBARI will embark on a expedition to study the submerged wreck of the airship USS Macon, the largest and last U.S.-built, rigid lighter-than-air craft.

A unique paper by researchers at MBARI and the Monterey Bay National Marine Sanctuary describes how a deep-sea communications cable affects animals living on and within the seafloor.

An international team of scientists recently announced the discovery of a new species of blind deep-sea crab whose legs are covered with long, pale yellow hairs. This crab was first observed in March 2005 by marine biologists using the research submarine Alvin to explore hydrothermal vents along the Pacific-Antarctic ridge, south of Easter Island.

A recent publication by researchers at the University of Rhode Island and at MBARI details the first observations of brooding in a deep-sea squid, with the mother carrying the eggs between her arms until the young hatch and swim away.

Each winter, storm waves sweep thousands of tons of beach sand along the coast of Monterey Bay. This sand is carried parallel to shore until it reaches Moss Landing, where it enters the head of Monterey Canyon.

As successful fishermen know, if you want to catch fish, you have to use the right bait or lure. This is true even in the deep sea, where scientists recently discovered a new species of jelly that attracts fish by wiggling hundreds of glowing red lures.

Jun 9, 2005 – After analyzing hundreds of hours of deep-sea video, Bruce Robison and his colleagues found that "sinkers"—the cast-off mucus nets of small midwater animals called larvaceans—are a significant source of food for deep-sea organisms.
