In recent years, I have taken to watching flying fish along the Maine coast. Not the usual flying fish that skim over tropical seas, but fish dangling from the beaks of flying puffins. Puffins are...
This deep-sea urchin ( Echinocrepis rostrata ) is an important “bulldozer.” It turns over sediment and exposes prey as it moves across the ocean floor, leaving a trail of tracks behind. This photo...
An Atlantic puffin ( Fratercula arctica ) carries many sandlances ( Ammodytidae ) in its mouth to take back to its hungry chick. Puffins have spiny tongues that, pressed against the roof of their...
Like octopods and cuttlefishes, giant squid have eight arms. But they use their two much longer feeding tentacles to seize prey. The tentacles have powerful suckers at the ends. More about the giant...
“It’s a little appreciated fact that most of the animals in our ocean make light,” says Edie Widder, biologist and deep sea explorer at ORCA. In this TED talk, she shows incredible film and photos...
Found in Arctic waters, this rare deep-water species of larvacean , Oikopleura gorskyi , eats by filtering particles from the seawater it drifts through. Larvaceans build 'houses' around themselves...
As we dive deeper into winter in the northern hemisphere, the possibility of snow becomes an increasingly frequent topic of conversation. But did you know that the ocean gets a regular dose of ‘...
Bull sharks cut a threatening figure with the largest recorded bull shark reaching 11.5 feet and 500 pounds. They prey on dolphins, birds, turtles, bony fish, and other species of shark. Catching...
I have a vivid childhood memory of sitting under the Blue Whale model hanging in the Natural History Museum in London, eating an ice cream and wondering “How in the world did that whale get so big?”...
The sargassum frogfish Histrio histrio (Antennariidae) is a small but voracious predator - it can ingest animals up to it’s own size! The fins of the frogfish are perfect for creeping around in the...
Frogfish are skilled hunters and some species are capable of blending into local environments such as coral reefs . A frogfish can camouflage itself so well that prey fish will swim close by without...
Humpback whales ( Megaptera novaengliae ) are the most abundant baleen whale in the nearshore waters around the Antarctic Peninsula. They, along with millions of penguins, seals, seabirds, and other...
One of the first signs of a sick coral reef is seaweed creeping across the corals, stealing their precious sunny real estate. Healthy corals, however, aren't completely hopeless: in some reefs, small...
When a whale dies, the story has just begun. The massive carcass sinks to the seafloor, where it provides food for a deep sea ecosystem on the otherwise mostly barren seafloor. There are several...
Is it an enormous eel? No—it's a shark! The frilled shark is named for its strange appearance , including a snakelike body, three pronged teeth, and gills that give the impression of a frilly collar...
Tiny Wilson's Storm-Petrels ( Oceanites oceanicus ) are not much bigger than sparrows, but are comfortable in wild oceanic conditions. To catch their small crustacean food, they gracefully dart and...
An orange brisingid starfish sits on a large reef of Lophelia pertusa, cold-water corals in the Gulf of Mexico, at 450 m depth as a school of fish swims above. They have many arms—up to 20!—covered...
Sperm whales have conical teeth on their long, narrow, lower jaw. The teeth fit neatly into sockets in the upper jaw, which has no teeth. This arrangement is a perfect adaptation for slurping up soft...
