The woodlouse, an ancient detritivore with over 300 regional names, is celebrated for its ecological role in breaking down plant matter and its ability to withstand toxic pollution. Nominated for Invertebrate of the Year, the article highlights its unique characteristics and the fondness people have for this common crustacean.
A study by Lancaster University and the University of Texas found that invasive rats on tropical islands decimate seabird populations, leading to nutrient loss in surrounding coral reefs. This nutrient reduction alters the balance of cryptofauna (tiny fish and invertebrates), favoring invertebrates over fish, and consequently rewires the entire reef food chain, with significant conservation implications.
Bug Hunt Australia, a citizen science initiative, has recorded over 1 million invertebrate observations since October 2025, engaging Australians in tracking insects, spiders, and snails. Led by the Invasive Species Council, the project uses the iNaturalist app to gather data, aiding scientists in identifying native species and detecting invasive threats like the Asian honey bee, crucial for biodiversity protection.
A new study reveals the algae responsible for a massive marine animal die-off in South Australia last year, Karenia cristata, is the most toxic species of its kind ever studied, with stronger toxic effects than previously known harmful algal blooms.
A massive bloom of common octopuses (Octopus vulgaris) in UK waters, first seen in Devon and Cornwall in 2025, has spread to Scotland and Wales, impacting the fishing industry and marine ecosystem due to warming seas.
Australian wildlife officers seize over 100,000 illegal cockroaches (Madagascar hissing and dubia) worth $142,000 from a breeder in NSW, emphasizing strict biosecurity laws against invasive species.
Lord Howe Island, off Australia's east coast, has witnessed a 60% increase in invertebrates (beetles, weevils, etc.) since the 2019 eradication of 300,000 invasive rats and mice, which had driven many native species to extinction.
Scientists have identified ancient octopus fossils belonging to genus Nanaimoteuthis, particularly Nanaimoteuthis haggarti, which may have grown up to 19 meters (62 feet) long—longer than a bus and possibly the largest invertebrate ever recorded. Analysis of 27 fossilized beaks reveals these creatures were apex predators in Cretaceous oceans, using intelligence and crushing bite force to dominate marine ecosystems alongside mosasaurs and plesiosaurs.
