The 'silent' invasion of a widespread freshwater jellyfish across Europe

A new study published in the journal People and Nature reveals a significant lack of public awareness about one of the world’s most widespread invasive species: the freshwater jellyfish Craspedacusta sowerbii. Despite being present on six continents and well documented by European scientists, this unnoticed (enigmatic meaning “under the radar”) invader remains largely unknown to the public, a factor that researchers say could hamper the development of early warning systems and effective environmental policy.
