Bionic jellyfish, to study world’s oceans
To strengthen and speed up the movement of jellyfish, researchers have used mini electronic devices. These electronic jellyfish were developed to explore the oceans in different parts of the world.

According to scientists, jellyfish are unique creatures as they navigate underwater by contracting their muscles. As part of the study, a 2-centimeter long electronic device was inserted into a moon jellyfish. The device prompted the jellyfish to move three times than usual. The researchers emphasized that the creature did not manifest any stress reactions despite undergoing the procedure. In fact, the jellyfish swam around normally when the device was uninstalled.

After the initial step’s success, the team is looking into controlling where the jellyfish travel. Developing sensors that could function even in the deeper parts of the ocean is one of their options. Bionic jellyfish are expected to perform deep dives, observe natural phenomena, and look out for signs of climate change underwater.
