For five years, engineer Nicole Sui has experimented with microelectronic devices that control the direction of swimming of jellyfish. The Sui device controls jellyfish, stimulating the contraction of their muscles. She then plans to equip them with sensors that can measure the ocean temperature and the pH level.
Aurelias are well suited for the study of the ocean because it is one of the most universal and energy efficient animals on Earth and occur even at extreme depths, 200 to 1000 meters, under the sea level in the Mariana depression.
Although the use of jellyfish is cheaper than sending people or the use of special equipment, Sui still explores the ethical issues related to their use. Although experiments on invertebrates are considered more ethical than mammals, recent studies call into question this assumption.
Jellyfish, like many other invertebrates, do not have a brain and spinal cord. They do not have pain receptors, although there are nerve networks. So far, in the experiments, the jellyfish did not show stress, for example, they did not secrete excess mucus and did not stop reproduction. However, the engineer advises to adhere to ethical principles in all future research.
