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...
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,...
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...

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...
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...
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...
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...
