Science Connected, , , ,

By Laura Treible @aqua_belle Jellyfish are a common nuisance to beachgoers in the summertime, but why certain years have massive jellyfish blooms while others do not is often a mystery. In recent years, some areas appear to have larger and more frequent blooms, so it is important to determine the causes of blooms in general, as well as whether jellyfish blooms are increasing.

Jellyfish might look like they are just drifting along with the ocean currents, but according to a new study of barrel jellies, these animals are moving with purpose. Researchers have found that jellyfish can detect ocean currents and actively swim against them. “Jellyfish are not just bags of jelly drifting passively in the oceans,” says Graeme Hays of Deakin University in Australia. “They are incredibly advanced in their orientation abilities.” It is believed that this is how jellyfish are able to congregate in blooms consisting of hundreds to millions of…
