Brainless Animal Turns Out to Be World-class Swimmer


Jellyfish do not have bones, a brain or a heart, but what they do have is incredible swimming skills, finds new research.

Jellyfish can detect the direction of ocean currents and swim strongly against them, according to the study, which is published in the latest issue of the journal Current Biology. The research adds to the growing body of evidence that creatures without brains, such as carnivorous plants, can still be clever.

“Detecting ocean currents without fixed visual reference points is thought to be close to impossible and is not seen, for example, in lots of migrating vertebrates including birds and turtles,” co-author Graeme Hays of Deakin University in Australia said in a press release.
