The basic body plans of all modern animals were set during the Cambrian Period, 542 - 488 million years ago. Your friends, family, and pet turtle may not look much like the creatures here. But we and...
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...
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—...
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...
Humans have long been captivated by what we now call the giant squid ( Architeuthis ). This image gallery gives a glimpe into our fascination with the animal. For a long time, people saw mysterious...
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...
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...
Inside the giant squid's sharp beak is a tongue-like organ called the radula (shown in yellow). Covered with rows of tiny teeth, it rams bite size pieces of food down the squid's throat. The pieces...
Sea squirts, or ascidians, are a diverse class of marine invertebrates representing about 2,300 species. As adults they are sessile animals (attached to the bottom) that feed by filtering food from...
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...
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 “...
Starfish—marine invertebrates of the phylum Echinodermata—are famous for their ability to shed limbs as a means of defense and then regenerate the sacrificed part. Ancient creatures, the fossil...
Today’s discoveries about our planet’s biological diversity build upon the research of previous generations of scientists. The Biodiversity Heritage Library (BHL) is a digital library committed to...
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 ,...
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,...
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.”...
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...
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...
