As Dampier studied the plants he encountered in Australia, he wrote that they were “for the most part unlike any I had seen elsewhere.” In fact, nearly all the plants Dampier observed were entirely...
Copepods are aquatic crustaceans found in every marine habitat, from surface waters to the deep sea. With over 13,000 described species, they are among the most abundant of all multicellular animals...
Published in 1882 by Yale Professor A.E. Verrill, this is the first scientific illustration of a giant squid. More about the giant squid can be found in the Giant Squid section .
Squids come in a wide range of sizes, from smaller-than-your-thumb to the enormous giant squid. Giant squid grow up to 16 meters (50 feet). Learn more the life, range, and ecology of the giant squid...
Rudist clams are mollusks that went extinct about 65 million years ago. They were the reef builders of the Cretaceous Period, the heyday of the dinosaurs. Today corals have taken over the role...
About 100 million years ago, during the heyday of the dinosaurs , reefs were built by mollusks called rudist clams . They looked very different from today's coral reefs . Discover more about the...
Nudibranchs (often casually called sea slugs) are soft-bodied, marine snails that have lost all trace of an external shell. The name “nudibranch” translates from the Latin as “naked gills.”...
What makes a top predator? Razor-sharp teeth? Speed? Strength? Size? Who is the most fearsome hunter? It depends on where and when you look.
The giant squid is among the largest invertebrates on Earth, but this deep sea creature has rarely been observed by humans -- alive. Over the centuries, many dead giant squid have washed up on the...
This illustration shows how Scarlet Knight , the first unmanned, underwater robot or glider to cross an ocean basin, faced an entire fleet of fishing ships, equipped with nets, threatening the glider...
Of all of the species Haeckel described, he is most famous for his illustrations of radiolarians. Planktonic, unicellular marine eukaryotes, radiolarians are found in all of the world’s oceans. The...
An adult giant squid struggles for survival in an encounter with a sperm whale - its only known predator. The whale will probably overpower and eat the squid. More about the giant squid can be found...
Hundreds of powerful suckers stud the flattened club at the end of the giant squid’s long feeding tentacle. They help the squid capture and hang on tightly to its prey. They also leave deep scars in...
Scientists met the robotic glider Scarlet Knight about halfway along its journey of scientific exploration from the United States to Spain, discovering that barnacles were growing on the glider’s...
Evidence shows that life probably began in the ocean at least 3.5 billion years ago. Photosynthesis began more than 2.5 billion years ago—the Great Oxidation Event. But it took hundreds of millions...
Dampier was not able to collect specimens of fishes and other ocean life. But he had his shipboard artist carefully record the species that Dampier found new and unusual.
This 1837 sketch is Charles Darwin’s first diagram of an evolutionary tree. It appears in his First Notebook on Transmutation of Species (1837).
Where ocean currents were strong, ancient rudist “recliners” lay unattached on the seabed. Notice the pink tentacles, which were used to filter feed. Learn more about ocean life throughout deep time...
