Achrioptera fallax is a stick insect species found in Madagascar. The males are a bright electric blue (with greenish tints) and have two rows of reddish orange spines along the edges of the femur. There are also dark coloured spines going along the sides and underneath the thorax. Males are brachypterous (incapable of flight) and have small reduced wings. Females have a duller outlook. They are a light brown with red spines covering the entire thorax and the top of the head. The male grows up to 13 cm in length while the female is much bigger and can grow up to 18, 5 cm in length. Their diet in the wild is unknown but in captivity they mainly feed on bramble, raspberry, eucalyptus, and oak.
This ghostlike octopod is almost certainly an undescribed species and may not belong to any described genus.
This species is particularly unusual because it lacks the pigment cells, called chromatophores, typical of most cephalopods, and it did not seem very muscular. It was found at
meters northeast of Necker Island (Mokumanamana) in the Hawaiian Archipelago
Gorgeous, Weird Jellyfish Found 12,000 feet Below the Surface Near Mariana Trench
The jellyfish in question was filmed earlier this week near the Mariana Trench during a submersible dive to explore an area called the Enigma Seamount. The jellyfish was spotted at a depth of over 12,139 feet. The NOAA researchers identified it as a kind of jellyfish called a hydromedusa, a part of the genus Crossota. Watch a video of it floating around.
Red Velvet Cupcakes. Or. Red Velvet Mites. You Choose…
Mites are among the oldest and most numerous organisms on the planet. They are diverse in form (30,000+ described species) and phylogeny (350 families) and extraordinarily abundant in a wide range of habitats, including your head. A couple of hectares or a few acres and you have the planets human population in mites. The group shown here are among the few that you might actually notice, unless you are an acarologist or obsessed with the little things. Pretty obvious why they are called red velvet mites, I reckon.
Sweet little things aren’t they? Just like cupcakes.
The amount of wildlife that fits in a cubic foot just might blow your mind.
That’s the subject of a new exhibition at our National Museum of Natural History, centering on the biocube—an actual 1-foot, green-framed cube that organisms can pass through. It’s a tool that researchers can place in environments anywhere in the world to study biodiversity over a 24-hour period.
Pictured above are the creatures from Mo’orea, French Polynesia, found by counting one cubic foot from a reef off the coast of the Pacific island.
“Life in One Cubic Foot” pairs science and photography in a quest to learn about the diversity of life on the planet.
IMPRESSIVE NEW FLASHER WRASSES SPECIES FOUND IN THE INDO-PACIFIC
The species in the genus Paracheilinus are appropriately called flasher wrasses (or simply flashers), and they are very closely related to fairy wrasses of the genus Cirrhilabrus.
This common name is derived from their grandeur “flashing” behavior observed during courting or mating where the male will make quick, exaggerated lateral moves while intensifying his colors and erecting his fins to attract a mate.

This is a new genus of Pseudachorutinae springtail (a subfamily of Collembola) known from several sites in southeastern Australia. It’s quite large for a springtail at about 3-4 mm long yet, like so many springtail species and genera, remains undescribed because it belongs to one of the (supposedly) less charismatic groups of organisms. For me, this little beast is oozing and dripping charisma. Just look at the little Dumbo-the-elephant-like face!
Once you discover invertebrate diversity it’s hard to go back to the vertocentric side!
Iberus gualtieranus is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Helicidae, the typical snails. This species is endemic to the Iberian Peninsula, Spain. It is classified as ’Endangered’ by the IUCN.
“It was a stunning scene—a 45-foot-long, 70-ton right whale hovering over the bottom just a few feet away from a diver standing on the bottom. … At some point I stopped and kneeled on the sand to catch my breath, and I was certain the whale would just keep swimming. Instead, the whale also stopped, turned, and hovered over me as it stared with that soulful eye. A few seconds later, I resumed swimming alongside the whale, making pictures, and savoring every second.”
This is a toad bug. Although predators, they don’t eat toads, at least not very often. Perhaps never. They’re actually named for their ‘toadish’ good looks.
Toad bugs belong the the true bug family Gelastocoridae with around 110 species (in three living genera) distributed across the much of the planet; they’re missing from the Palearctic (Europe and northern Asia). Two genera, Gelastocoris and Montandonius, are American, found in riparian habitats from Canada to Argentina, and the third genus, Nerthra, is more widely distributed with species in the Americas, Australia, southern Asia, Madagascar and Africa and a few islands between and about.
Gelastocorids belong to the true bug grouping called the Nepomorpha. The Nepomorpha is an ‘infraorder’, an ugly word, but one meaning a classification level lower than suborder but higher than superfamily; bet you didn’t learn that at school. The Nepomorpha are dominantly aquatic bugs and the Gelastocoridae represent a group that has likely, secondarily, become terrestrial. That is the ancestors were terrestrial, became aquatic, then some lineages returned to land. Weird. Make up your mind toad bugs.
Here in Australia there are about 25 species, all in the genus Nerthra, and found in mesic eastern and southwestern Australia. The images show one species from the Dandenong Ranges National Park, just outside Melbourne. In contrast to Gelastocoris, Australian Nerthra are commonly encountered in leaf litter distant from water bodies. They can be a significant component of forest leaf litter samples where they are dominantly represented by larval forms, rather than adults.
The adult, shown here, can be recognised by the hemelytra (like elytra in beetles) clearly visible in the second image as the leafy ‘wings’ which cover the abdomen. The fore limbs with their distinctive spike-like tibia and tarsus combination are clearly suited to ambush hunting with the prey impaled by their front legs. So I suppose they could eat toads, just little ones…
Many frog species in Honduras are at risk of extinction from chytrid fungus, like this critically endangered Ptychohyla hypomykter treefrog from my frog rescue site in Cusuco National Park. Tomorrow, I’ll be sending out our next big #HARCC frog rescue project update! So keep an eye on this page! on.fb.me/1WRMIRE (March 5 UPDATE!! Our first frog rescue video now added at the top of my page! Check it out!)
The shingle urchin is a species of sea urchin in the family Echinometridae. It is found on wave-swept intertidal shores in the Indo-West Pacific, particularly on the shores of Hawaii. This urchin is a deep maroon colour and shaped like a domed limpet. It can grow as big as a soft ball but is usually much smaller. The
upper surface is a mosaic of tiny polygonal plates formed from modified
spines to form a smooth mosaic. This is fringed by a ring of large,
flattened modified spines. On the underside there is another ring of
smaller flattened spines and a large number of tube feet. This urchin is usually found on substrates fully exposed to waves and their associated abrasive effect, often in groups. It feeds on periwinkles, other urchins and coralline algae.
A University of Toronto-led team has reported the discovery of a new lizard in the middle of the most- visited island in the Caribbean, strengthening a long-held theory that communities of lizards can evolve almost identically on separate islands.
The chameleon-like lizard - a Greater Antillean anole dubbed Anolis landestoyi for the naturalist who first spotted and photographed it - is one of the first new anole species found in the Dominican Republic in decades.
“As soon as I saw the pictures, I thought, ‘I need to buy a plane ticket,’” says Luke Mahler of U of T’s Department of Ecology & Evolutionary Biology and lead author of an article on the discovery published today online in The American Naturalist.
“Our immediate thought was that this looks like something that’s supposed to be in Cuba, not in Hispaniola - the island that Haiti and the Dominican Republic share,” says Mahler. “We haven’t really seen any completely new species here since the early 1980s.”
What’s more, the new species could help piece together a long-standing puzzle of similar looking species that exist on different Caribbean islands.
Modern fish make up a huge part of Earth’s ecosystems, and cover a lot of niches. Predators, omnivores and herbivores are all found in this diverse group. Millions of years of adaptation has sculpted their bodies into the various forms and shapes we see today.
Looking beneath the surface of a fish’s skin can reveal a lot about the ecology of fish – the most diverse group of vertebrates on Earth. Use our image sliders to see under their scales.
