Invertebrate of the Year 2025: Vote for Top Spineless Species 2026

Invertebrate of the Year 2025 is back, and this year’s contest celebrates the magnificent array of 1.7 million invertebrate species that share our planet. From microscopic tardigrades to colossal squid, these spineless wonders perform essential jobs—recycling waste, pollinating crops, and filtering water—while bringing joy to nature lovers worldwide. Now, it’s time to vote for your favorite among the top 10 nominees, as selected by over 1,300 readers.

Why Invertebrates Matter for Biodiversity

Invertebrates are the backbone of ecosystems, yet they often go unnoticed. They are the unsung heroes that keep our environment balanced. Without them, our soils would be barren, our crops unpollinated, and our waters murky. Their diversity is staggering, and each species plays a unique role in maintaining the health of our planet.

This year’s contest highlights both the tiny and the towering. The 2025 winner, Milnesium tardigradum, is microscopic, but other nominees like Bombus dahlbomii, a Patagonian bumblebee, measure up to 4cm long. This range showcases the incredible adaptability and variety among invertebrates.

Top 10 Nominees for Invertebrate of the Year

Here are the standout species that made it to the final round, each with unique traits that capture our imagination:

• Bombus dahlbomii – The giant Patagonian bumblebee, a fluffy pollinator attracted to red flowers.
