CANADA: A recent study found out that moon jellyfish have an unusual way of survival. They don’t regrow their bruised limbs. Instead, they rearrange their entire body to stay symmetrical despite the loss. This mechanism enables them to live indefinitely.
This marks as the first time that the scientists ever witnessed this phenomenal event. Many invertebrates can grow limbs but experts were shocked to see how the jellies retained their symmetry after the loss of a limb.
“We’ve now observed another self-repair mechanism,” Michael Abrams, study researcher and graduate student of biological engineering at the California Institute of Technology (Caltech), said in an interview.
The moon jellyfish began moving their remaining arms around their bodies, hours after losing a limb, to regain their symmetry. The jellyfish that lost four of its limbs became a symmetrical snowflake again in as quickly as just four days.
The researchers investigated how the jellyfish managed to rearrange their bodies. They suspected that jellies were growing new cells to push their remaining limbs apart so that the arms would be spread evenly. But when researchers tried to prevent the cell reproduction, the jellyfish still managed to regain their symmetry.
The experts found that if the jellies did not move, they could not manage to become symmetrical again. No movement, no symmetry, as the experts put it. The muscular movements of the animal cause the regular pulsations that rearrange the limbs around its body.
