Step into the underground world of New Zealand’s Waitomo Caves and you’ll witness one of the most enchanting natural wonders on the planet. In total darkness, a galaxy of tiny blue lights twinkles all around – created by thousands of glow worms clinging to the cave ceilings. These spellbinding creatures are arachnocampa luminosa, a species unique to New Zealand. Although called worms, they are actually the larvae of a fungus gnat.

Humpback whales have been spotted blowing bubble rings towards humans in a newly documented behaviour that researchers believe may be playful or communicative. It's the first time humpback whales have been observed creating stable bubble rings during friendly interactions with humans, such as approaching swimmers or boats, say the researchers, who suggest that these floating rings, which resemble the smoke rings blown by humans, may represent a novel form of non-human expression or curiosity.

In the wetlands of the Paraná Delta, just north of Buenos Aires, there is a curious island known as El Ojo. What's strange about it? To start with, it floats. It's also a near-perfect circle that sits inside a lake, which itself is circular. Stranger still, El Ojo appears to rotate and shift its position over time. From the air, this fusion of characteristics makes the island look like an eye – hence its name, El Ojo, which translates into English as 'The Eye'.

The fossil, which belongs to the species Dacentrurus armatus, is the most complete stegosaurian skull ever unearthed in Europe and has led to the proposal of a new evolutionary group: Neostegosauria.

More than 500 small blue butterflies have been spotted at a single site in Scotland – a record-breaking number for one of the UK’s most threatened butterflies. Butterfly Conservation volunteer Richard Aspinall logged 523 small blues in just 90 minutes at Balnagown Estate near Invergordon. It more than doubles last year’s total and marks a hopeful sign for the species’ future, say conservationists.
