It’s raining in Melbourne as I write this, and on my approach to work I noticed pale pink earthworms all over the place, scattered and uncovered all around the footpath like soft-bodied streamers.
It was a visual reminder, as I dodged to keep away from squishing the inaugural winners, in 2024, of the invertebrate of the yr contest, of the magnificent array of 1.7m invertebrate species we share the planet with.
The Guardian’s annual celebration of the spineless offers us an opportunity to understand and have fun invertebrates in all their weirdness and magnificence, whether or not they be furry, fast-flying, gelatinous or beady-eyed.
We’re fortunate to have them, in spite of everything, and never only for the roles they carry out – recycling our waste, pollinating our crops, and filtering our water – but in addition for the enjoyment they create (hiya, bumblebees!). Particularly when a lot of the world’s biodiversity information is devastating.
Greater than 1,300 readers have nominated their favourites. We now have weevilled it all the way down to the highest 10. Now, it’s time for you to vote – after this week’s most essential reads.

In focus
It’s simple to think about invertebrates as small, significantly as our 2025 winner – Milnesium tardigradum – is actually microscopic. To stability the size, this yr’s contest options some marvellously big-bodied bugs (though none so massive because the colossal squid, the heaviest invertebrate on the planet).
Take, for instance, Bombus dahlbomii, a bumblebee discovered within the mountains of Patagonia, which measures as much as 4cm lengthy and is interested in pink flowers. “Bumblebees are the pandas of the insect world, and a mascot for biodiversity conservation,” says bee nominator and researcher Anton Gradišek in Ljubljana, Slovenia.
I agree, though should you aren’t but captivated with their bumble behaviour – take a look at the footage of them playing with wooden balls, or licking their tongue-like glossa after tasting one thing candy – then there’s a very good likelihood this yr’s large ginger fuzz ball affectionately often called “flying mouse” could also be sufficient to tip you over the sting (though, do take a look at its cute however tiny competitor, the leaf sheep, a solar-powered sea slug with doe eyes that spends its days grazing on algae).
One other enormous contender, the supersized Lord Howe Island supermodel (Dryococelus australis), gives us a observe of hope with its conservation comeback story. One of many rarest invertebrates on this planet, the 20cm-long “strolling sausage” was thought extinct, solely to be rediscovered in 2001. The species has since been efficiently bred in captivity and there are plans to reintroduce them again to the island.
Too candy? Too hopeful? Readers with extra macabre tastes could want the bootlace worm (Lineus longissimus), a metres-long, blackish-brown creature that discharges a poisonous ooze and smells like sewage.
If their pet names are something to go by, a few widespread critters have already captured hearts, and will quickly seize votes.
The widespread woodlouse (Porcellio scaber), a small brown isopod that feeds on rotting crops and breaks down wooden, has greater than 300 regional names in Britain alone, and extra in different places and languages. Right here in Australia, I’ve identified our native variants as “slaters”, or “butchy boys”, however will henceforth be adopting “witch of the wooden” (gwrach y coed in Welsh).
Many widespread cicada names in Australia have been coined by youngsters, making some sound a bit like marbles or superheroes. The greengrocer, which pronounces its presence in Sydney and Melbourne with an ear-splitting refrain, has an evocative alias – yellow Monday or masked satan – for each color.

The wandering glider, a world citizen, has conquered each continent besides Antarctica, and might be discovered from sea stage to six,000 metres excessive. Nevertheless it was the glider’s migration throughout 18,000km that led Ben Worth, principal curator of entomology on the Pure Historical past Museum in London, to name it “ubiquitous, fearless, and quietly astonishing”. Not in contrast to neon flying squid (Ommastrephes bartramii), which leap from the water in unison just like the early levels of an alien invasion.
Our shortlisted topics boast many outstanding skills, however nothing like Turritopsis dohrnii, which has cracked the code to everlasting life. This tiny thimble-shaped jelly performs one in every of “nature’s coolest methods”, in keeping with its nominator, Raquel López-Aragón. “When this jellyfish will get previous or damage, as a substitute of simply dying like most animals, it transforms itself again right into a child jellyfish and grows up another time.”
Whereas the immortal jellyfish does precisely what it says on the tin, the identical can’t be mentioned for the horseshoe crab – residing fossils that aren’t even crabs – with blood that runs blue somewhat than pink.
As Patrick Barkham wrote on the outset of this yr’s competitors: “We, creatures with spines, are a tiny minority within the animal world. People, canine, cows, birds, fish – we might imagine we’re the planetary rulers, however we’re not. We make up barely 5% of animal life on Earth.”
Mere vertebrates can solely look on in awe on the unimaginable variety and aptitude of those invertebrates. Each one of many prime 10 is curious and particular in its personal approach – and greater than deserving of your vote.
Though, if I could, I’d put in a single last plug for the immortal jellyfish – in spite of everything, if it doesn’t win, it might simply hit reset on the entire thing and begin once more.
