The Ancoracysta twista is a single-celled eukaryote. It uses the flagella visible in this image to propel itself around as it hunts other tiny organisms.
Ancoracysta twista was discovered in an aquarium in San Diego, California, USA. It’s a new single-celled protist that has challenged scientists to determine its nearest relatives.
These Dinizia jueirana-facao trees, also known as Atlantic forest trees, are found only in and near the Reserva Natural Vale in Espirito Santo, Brazil.
A Dinizia jueirana-facao tree weighs an estimated 62 tons (56,000 kg). The tree species is limited — there are only 25 known individuals, about half of which are in a protected area, making it critically endangered.
The Epimeria quasimodo amphipod is about two inches long and comes from a genus that's abundant in glacial waters.
Epimeria quasimodo is one of 26 new species of amphipods of the genus Epimeria from the Southern Ocean. It is named for Quasimodo the hunchback in reference to its shape.
The Nymphister kronaueri isn't an ant — it's a tiny beetle that disguises itself as the abdomen of an army ant.
Nymphister kronaueri is a beetle that lives exclusively among one species of army ant, Eciton mexicanum. The beetle’s body is the precise size, shape, and color of a worker ant’s abdomen. The beetle uses its mouth-parts to grab the skinny portion of the host abdomen and hang on, letting the ant do the walking.
When the nomadic ant colonies stop for a few weeks to make raids, the beetles move about, but they reattach before the ants move on.
The Pongo tapanuliensis orangutan was recently discovered to be a distinct species of great ape.
Pongo tapanuliensis is the most imperiled great ape in the world. Only an estimated 800 individuals exist in its fragmented habitat in Sumatra. Here we see an adult male Tapanuli orangutan named Togos.
Pseudoliparis swirei, also known as the Mariana snailfish, is the deepest known fish in the sea.
Pseudoliparis swirei is a small, tadpole-like fish measuring a little over 4 inches in length (112 mm). It appears to be the top predator in its community at the bottom of the Mariana Trench.
Sciaphila sugimotoi is one of the few plants in existence that's heterotrophic, meaning it gets sustenance from other organisms. These flowering plants have a symbiotic relationship with a fungus that gives them nutrition.
Sciaphila sugimotoi is just under 4 inches in height (10 cm), and produces small blossoms in September and October.
A colony of Thiolava veneris first appeared after a volcanic eruption in the Canary Islands.
Thiolava veneris was the first colonizer after a 2011 eruption of the underwater Tagoro volcano off the coast of the Canary Islands. Scientists discovered the bacteria three years after the eruption — it formed a half-acre sized white mat around the volcanic cone.
This reconstruction of Wakaleo schouteni shows a marsupial lion that weighed about 50 pounds and stalked the forests of northwestern Queensland 23 million years ago.
Scientists from the University of New South Wales recovered fossils in Australia's Riversleigh World Heritage Area that proved to be a previously unknown marsupial lion. They determined that Wakaleo schouteni roamed the open forest habitat in northwestern Queensland in the late Oligocene, which ended about 23 million years ago.
The Xuedytes bellus beetle resembles others that have adapted to life in the permanent darkness of caves.
Xuedytes bellus is less than half an inch in length (about 9 mm). It has a dramatically elongated head and prothorax (the body segment immediately behind the head to which the first pair of legs attach). It was discovered in a cave in Southern China.
