Jellyfish under attack: Study uncovers parasitic spillover of a burrowing sea anemone

Many marine organisms, like sea anemones, struggle to spread across the ocean, especially if they lack long, mobile larval stages. Unlike their jellyfish relatives, sea anemones do not have a medusa stage, making their dispersal challenging. Their only mobile stage is a tiny larva called a planula. Many marine organisms, like sea anemones, struggle to spread across the ocean, especially if they lack long, mobile larval stages.
