A study published in the journal Nature-Communication says that a jellyfish-like organism called a tube jellyfish forms a group with high mobility. During exercise, members of the community at different stages of development have different divisions: the older provides power in the rear and the younger in the front. Researchers say this simple and effective organization can help people improve the design of underwater propulsion.
Pipe jellyfish is a gel-like organism that is related to jellyfish, sea anemones and corals. It has the most complex group-level relationship in the animal kingdom.
In this community, there are a group of individuals whose genes are identical. They are called swimming clocks. Together they form the "propulsion engine" of this group of creatures, which can push the water backwards like a jet plane. The individuals that are dragged behind are dedicated to breeding and eating.
John Costello of the American Marine Biology Laboratory and his research team used image tracking to explore how this "multi-jet propulsion system" works. They found that the young, smaller, double jellyfish's swimming bells were at the front end of the group of animals and used their jetting behavior to influence the direction of advancement; older and larger swimming bells provided forward or backward. Propulsion to ensure daily migration.
This division of labor is considered to be the key to group survival. The unique mode of cooperation guarantees that important tasks can be performed by both the elderly and the young in the entire group, and their developmental structure makes this cooperation possible.
Researchers believe that this simple and effective multi-engine organization can help improve the design of underwater propulsion.
