This is Trapezia rufopunctata, a small and brightly coloured species of crab native to the lagoons and coastal reefs of the Maldives, Polynesia and the Indo-Pacific region. Also known as a guard crab, it lives symbiotically with corals, feeding on their discarded tissue and mucus while defending them from predators. ...

Researchers studying a group of wedge-capped capuchin monkeys that live in tropical forests of central Venezuela have discovered that the monkeys protect themselves against the annual merciless onslaught of mosquitoes exactly as humans do: by rubbing themselves with mosquito repellent.

But while humans may reach desperately for spritzers or bottles or laughably overhyped ''protective'' skin-so-softeners, the capuchins have learned to poke around in tree bark or termite mounds to extract a wriggling specimen of Orthoporus dorsovittatus, a millipede rich with powerful defensive chemicals called benzoquinones.

The capuchin monkey will then proceed to anoint itself head to foot with the repellent secretions by massaging the four-inch-long millipe ...

This is the happy face spider, a spider in the family Theridiidae. Their "smile" keeps predators away.

New data shows alpine swift can spend up to 200 days in the air.

It is a mystery how the birds are able to physiologically accomplish this feat. While their diet is relatively straightforward, they feed on airborne insects, how they rest in midair is not known.

Introducing the Honduran white bat, a tiny bat (reaches up to 4.7 cm in length) found in Honduras, Nicaragua, Costa Rica and Panama that has superb construction skills. These bats build tents from waxy leaves, creating a waterproof shelter that also helps them camouflage from predators.

Otherwise known as the Door to Hell and the Darvaza gas crater, the crater is found in Turkmenistan and is 60 metres wide and 20 metres deep. The hole was created when a Soviet drilling rig accidentally tapped into a massive underground natural gas cavern, causing the ground to collapse and the drilling rig to fall in. To prevent poisonous fumes from escaping into the atmosphere, the Soviet geologists decided to set the pit on fire, hoping the fire would use up its fuel in a few days.

This picture of a green and red aurora was taken on September 26, 2013, from the International Space Station. The colours of the aurora borealis depend on which atoms the solar storm excites. Green auroras appear when charged particles from the solar wind crash with oxygen atoms in Earth’s atmosphere and produce green photons; red auroras occur when the particles collide with nitrogen atoms or when there are lower-energy oxygen collisions, producing red photons.

This is the Giant Leopard Moth, a strictly nocturnal species native to parts of North America and Mexico. These moths start life as an incredibly black and bristly caterpillar, and once they grow into adulthood, they never eat, and instead focus on mating and passing their genes onto several clutches of eggs. ...
