Jellyfish Sense Ocean Currents
24 Jan 2015
Jellyfish can sense the ocean current and actively swim against it, according to a study that involved tagging and tracking the creatures.
The research, by an international team, could help scientists work out how jellyfish form "blooms".
These blooms may comprise between hundreds and millions of jellyfish, and can persist in a given area for months.
It remains unclear just how the jellyfish sense changes in water, the paper in Current Biology journal says.
