Press release: Treasure trove of data on worms in Europe's seas

No. 15 - 11.02.2026

Research team including Göttingen University collaborate on EuroWorm project to study marine worms

Species are disappearing at an alarming rate worldwide – accelerated by climate change, habitat loss and invasive species. Little-studied groups, including many marine worms, are particularly affected: species are threatened with extinction before they have even been scientifically described. Researchers from the University of Göttingen, the Leibniz Institute for Biodiversity Change Analysis (LIB) and the Senckenberg Society for Nature Research will build a comprehensive dataset on European “marine annelids” – segmented sea worms – and make it openly accessible for international research. This should advance the discovery of new species and the knowledge of biological diversity worldwide. The project “EuroWorm: Accelerating Global Marine Annelid Biodiversity Research with Open Genomic Data for European Species” is led by the LIB and funded by the Leibniz Association.

Marine annelids play a role in almost all marine habitats: they mix sediments, recycle nutrients, are indicators of pollution, and are an important part of the food web. The project team plans to take samples in places in Europe where typically hundreds of species were first described. The researchers will identify the animals collected there morphologically – meaning by their form, structure or shape –, photograph them in high resolution, and examine them using modern genomic and other cutting-edge methods. The aim is to create a genomic inventory of European marine annelids, to find answers about the classification of groups in the evolutionary family tree, and to investigate how their physique, reproduction, and lifestyle have changed in the course of their evolution.

The worms, along with their images and genome data, will be added to the collections of the LIB at the Museum of Natural History Hamburg and the Senckenberg Natural History Museum. Researchers worldwide, especially in the Global South, can borrow specimens and access the data via the LIB and Senckenberg portals and platforms such as GBIF. “By comparing data on European species, we hope to accelerate the discovery of new species and biodiversity research worldwide – and thus counteract the ‘silent extinction’ of marine species,” explains project leader Dr Jenna Moore from the LIB. At the same time, the project aims to strengthen the role of natural history museums as state-of-the-art research infrastructures.

Three researchers at Göttingen University’s Animal Evolution and Biodiversity research group are participating in the project. “Such collections are scientific time capsules”, says Dr Maria Teresa Aguado Molina: “Historical collections, combined with modern genomics, are unlocking hidden biodiversity at an unprecedented pace. EuroWorm shows that the most advanced discoveries begin with specimens collected decades ago.” Professor Christoph Bleidorn emphasises that research into the evolution of annelids has a long tradition in Göttingen: “This means we are all the more delighted to be able to pursue these questions further as part of a project funded by the Leibniz Association.”

The EuroWorm project is a unique opportunity to pool the expertise about methods of multiple institutions. According to Dr Conrad Helm, “The comprehensive, interdisciplinary approach provides an excellent basis for thoroughly documenting the diversity of marine annelids and, at the same time, for specifically defining future research priorities.”
