World's Largest

Scientists have discovered the largest known protein in biology. Given the fun name of PKZILLA-1, the protein was found in algae cells and helps them make toxins that are responsible for mass killings of fish.

Scientists have discovered the organism with the largest known genome. At 160 billion base pairs, it's 50 times bigger than the human genome, and the organism it’s describing is a tiny fern you wouldn’t even notice if you tripped over it on a hike.

A newly described species of marine reptile could be the largest to ever swim the world’s oceans. The “giant fish lizard” lived more than 200 million years ago, and may give the blue whale a run for its money, size-wise.

The blue whale has long been considered the largest animal to have ever existed, even dwarfing the biggest known dinosaurs. But now a new species threatens to steal the crown, and upends what we thought we knew about whale evolution.

Scientists have discovered the fossil remains of what may be the largest penguins that ever lived. The bones, found on a beach in New Zealand, belonged to a giant bird that was more than three times the size of the biggest living penguins today.

Researchers have discovered the largest plant in the world – a meadow of seagrass off the coast of Western Australia that covers a total of 200 sq km (77 sq miles). The entire expanse has grown from just one seedling, spreading by cloning itself.

Paleontologists have discovered the largest raptor dinosaur ever found. The new species, known as Maip macrothorax, was a super predator of the megaraptor family that stalked the forests of Argentina some 70 million years ago.

Biologists have discovered the largest bacterium ever found, with a single cell measuring a mammoth 2 cm long. Visible to the naked eye, this new species has bizarre characteristics that make it like a missing link in the evolution of complex cells.

German scientists have announced the discovery of what is claimed to be the world's largest fish breeding area known to date. Described as a globally unique ecosystem, it consists of tens of millions of icefish nests on the Antarctic sea floor.

Blue Abyss Ltd. is building the world's largest and deepest indoor pool in Cornwall. Holding as much water as 17 Olympic-sized swimming pools, it will be used for advanced undersea robotics and as the world's first commercial astronaut training facility.

​Back in 1991, paleontologists from the University of Alberta discovered the remains of a Tyrannosaurus rex in the province of Saskatchewan. Nicknamed "Scotty" in honor of a celebratory bottle of Scotch that was enjoyed when its skeleton was found, it has now been declared the world's largest T rex.

​Back in 1998, scientists from the University of Kansas unearthed a gigantic fossilized dinosaur foot in the Black Hills of Wyoming. Nicknamed "Bigfoot" at the time, it's now been officially certified as the largest dinosaur foot ever found.
