Experts have found that the jellyfish cubes remember their past bad experiences and can apply that knowledge.
Jellyfish cubes that lack a brain can learn from their past mistakes. This conclusion was reached by an international group of scientists who conducted an experiment involving a species of box jellyfish Tripedalia Cysophora.
The scientists tried to teach it to adapt to the conditions using its previous experiences. As part of the experiment, the scientists placed the jellyfish in a round-shaped tank with striped walls that mimicked the vertical stripes of a mangrove. So the researchers wanted to find out if the jellyfish could avoid collisions with glass, according to a paper published in Current Biology.
At first they did not succeed, and they constantly collided with the protruding walls of the tank. However, by the end of the 7.5-minute trial, they had learned to turn more often and doubled the distance between themselves and the wall. According to the scientists, this indicates that the jellyfish changed their behavior in response to the obstacle based on past experiences.
Now scientists plan to study how nerves are interconnected at the cellular level.
Earlier it was reported that on the beach near Anapa on the shore threw atypical for the Black Sea huge blue jellyfish.
