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.”...
Haeckel was inspired by nature to create not only stunning scientific illustrations but also decorative pieces for home interiors. Haeckel discovered a species of rhizostome jellyfish in Bellagemma,...
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...
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 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 .
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...
This slideshow features illustrations of some of the plants and animals that William Dampier, a naturalist and pirate, observed in Australia (then known as New Holland) and New Guinea. Learn more...
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...
The siphonophores are an order of marine animals in the phylum Cnidaria (the same phylum containing jellyfish ). Although they superficially resemble jellyfish, each siphonophore specimen is actually...
Historically, sea urchins were known as sea hedgehogs due to their superficial resemblance to the spiny mammalian species. “Urchin” is, in fact, a Middle English term for hedgehog. Sand dollars (like...
Earth’s first animals had soft bodies. This illustration shows a community of soft-bodied Ediacaran (edi-A-karan) animals. Some species resemble living ocean creatures. Others are unlike any known...
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 “...
Vertebrates evolved in the sea and eventually moved onto land. The ancestors of whales later returned to the sea, taking advantage of its rich food supplies. As early whales adapted to their new...
Crinoids (echinoderms related to sea stars and sea urchins) dominate the Paleozoic shallow water habitat in this illustration. They evolved a variety of stalk heights, which enabled them to capture...
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...
Like the modern nautilus, this relative of modern squid hunted from inside the safe haven of a protective shell. Ammonites went extinct around the same time as the dinosaurs—65 million years ago...
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...
