This illustration shows the edge of a warm inland sea during the Cretaceous Period, heyday of the dinosaurs. Constantly shifting sediment supported new groups of organisms, including rudist clams—...
Humans are late arrivals on Earth. For nearly 75% of Earth’s history, life consisted of single-celled microbes without a nucleus (prokaryotes). Volcanoes and erosion sculpted Earth 3.5 billion years...
The waters of New Guinea teemed with exotic fishes and crabs, which were faithfully depicted by William Dampier’s artist. When Dampier’s book A Voyage to New Holland was published in 1703,...
Squids come in a wide range of sizes but despite differences in size and shape, all work basically the same way inside. More about the giant squid can be found in the Giant Squid section .
Offshore Peru, during the Eocene (~56-34 million years ago), showing three archaeocetes (ancient whales), along with a previously described fossil penguin. Top to bottom: Perudyptes devriesi ,...
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...
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 .
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...
In 1699, accompanied by a shipboard artist, William Dampier conducted the first scientific investigation of the plants and animals of Australia (then known as New Holland). From there he and his crew...
A scientific illustration of the most powerful fish of its time, Carcharodon megalodon , which swam the ocean 30 million years ago. This shark may have reached a size of 20 meters/66 feet. Meet other...
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...
This illustration shows one old idea of what the ancient shark Helicoprion might have looked like. There once was room for many ideas—some more plausible than others—because the only fossils of the...
After leaving Australia, Dampier and his men reached the western coast of New Guinea on New Year’s Day 1700. There Dampier observed birds that he had never seen before, like the “stately land-fowl”...
A sea monster attacks a ship in an illustration for 20,000 Leagues Under the Sea by Jules Verne. The illustration is by publisher and artist Pierre-Jules Hetzel, who is most famous for his drawings...
How do right whales size up? North Atlantic Right whales ( Eubalaena glacialis ) are big, but they're not the biggest whales. That distinction goes to the Blue whale ( Balaenoptera musculus ), the...
As soon as Dampier set foot in Australia, he began making observations and collecting specimens of plants, which he carefully pressed between the pages of books to be studied by the “ingenious” and “...
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...
