The illustration is by publisher and artist Pierre-Jules Hetzel, who is most famous for his drawings in Verne's books. This terrifying monster looks a lot like an octopus or squid, which do little harm to people. Read about how author Ray Bradbury encouraged people to sympathize with sea beasts in one...Read more

Many sperm whales stranded on beaches or caught by whalers exhibit telltale circular scars like these. Only one thing could have made them: the strong suckers that line the giant squid’s eight arms and two long feeding tentacles. Older sperm whales have so many scars that they overlap each other. Learn more about the over-sized anatomy of the giant squid in this video with Smithsonian scientist...Read more

Remember playing Tetris? Originally developed in 1984, the video game in which blocks of various shapes rain down and the player needs to find a way to fit them together is now ubiquitous. This TED ED video compares Tetris blocks to carbon dioxide being released into the atmosphere and reabsorbed by plants and ecosystems as a part of the carbon cycle. But what happens when you can't keep up with...Read more

These star-shaped grains of sand, collected from southern Japan, look like miniature works of art -- but they were not sculpted by an artist. They are the shells of microscopic organisms called foraminifera , which build intricate shells from the calcium carbonate they collect while drifting through the water. Their shells have settled on the seafloor for 500 million years, and are used by...Read more

Two bright orange anemonefish ( Amphiprion ocellaris ) poke their heads between anemone tentacles. Anemonefish are able to swim amongst the stinging tentacles without getting stung — but no one knows exactly sure how. One dominant theory explains that they have a protective slime coating their bodies. However, anemonefish are not born with this protective slime and scientists don't know how they...Read more

The pearly razorfish’s name may be slightly misleading since it is neither as rare as a pearl nor as dangerous as a razor. It is a common fish that tends to live in clear shallow areas near seagrass beds and coral reefs, where it collects coral debris to build its nests. However, even having a home may not be enough to put this skittish fish at ease. When startled, the pearly razorfish will...Read more

White abalones are slow-moving, algae-eating mollusks. Rapid overharvesting since the 1970s has resulted in white abalones becoming the first marine invertebrate listed as endangered on the Endangered Species Act in 2001 . The population is struggling to recover because they need a mate nearby in order to breed—a difficult task with a small and scattered population. A 2010 assessment stated that...Read more

When hoping to discover a pearl, looking inside one of the oysters you slurp may not be the best plan. Food oysters in the family Ostreidae are able to produce pearls, however these tend to be small, irregular, and worth very little . Most pearls strung on necklaces come from pearl oysters, which are in a whole different bivalve family! Pearl oysters create pearls when a hard particle is coated...Read more

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 researchers with the Census of Marine Zooplankton (CMarZ), a project of the Census of Marine Life , dove 1.8 miles (2,800 meters) to first discover Teuthidodrilus samae in 2007...Read more
