A gene drive is a radical new way of re-engineering the genetic makeup of an entire species - including harmful insects like the mosquito. But as the technology steams head, fueled by powerful gene editing techniques coming out of synthetic biology like CRISPR Cas9, what are the risks, and how can w
Echidnas are egg laying mammals. Along with the platypus, the four living echidna species are classified in the monotreme order. Monotremes are mammals and thus produce milk for their young and create their own heat (along with other mammalian traits) but this unique mammals have a cloaca and lay eg
The sperm whale is the largest toothed whale. They have 20-26 teeth on each side of their lower jaws. Technically they have upper teeth, too, but these are vestigial and rarely erupt. Sperm whales are deep ocean dwelling animals making dives up to 6,500 feet (2,000m) to find food in the form of gian

When they tail breaks, it may sometimes do so in pieces, which has led to the myth that these lizards can piece their tails back togeth
Kissing bugs are from the groups of insects commonly called assassin bugs. These arthropods are well known as the insects responsible for the spread of Chagas disease, though they don't actually give the disease to people through their bites (which are typically made around a person's mouth). There
Antlions are the things of nightmares. Apparently there are people who don't believe these animals exist, but they are absolutely real. Antlions are also known as doodbugs and they build pitfall traps for any would-be passersby insects who are unfortunate enough to fall in. At the center of these pe
Lungless salamander don't have lungs so they aren't able to inhale in order to smell their surroundings. Instead, they use a special groove on their upper lips that move water and scent particles to their nostrils giving them access to the scents all around them! These amphibians obtain oxygen throu
Also known as the pig-nosed turtle, the Fly River turtle is a strange turtle indeed. The Fly River turtle could be described as a cross between a softshell turtle and a sea turtle. Softshell because it has a shell lacking scutes just like a softshell turtle, and sea turtle because it has large front
The common name "barn owl" may be in reference to a single species, but it can also describe the group of approximately twenty living species in the barn owl family. The barn owl family includes any owls not classified as "true" owls and they all have heart-shaped faces. There are sooty owls, masked
The Humboldt squid is also known as the red devil squid and the jumbo flying squid. These cephalopods don't quite reach the gargantuan sizes of giant and colossal squid, but they can still pack a punch with their fist sized beaks. Humboldt squid live along the Pacific coasts of the Americas partakin
