Staying symmetrical, staying on even keel

Oceaniske shapeshifters

Animals are endowed with the capacity to repair injuries. Some animals simply heal the wound, whereas others are able to regenerate lost parts.

A new study now documents yet another and previously unidentified strategy of self-repair, where moon jellyfish respond to injuries by reorganizing existing parts, and rebuilding essential body symmetry, important for them to stay balanced as they travel around the ocean, without regenerating what is lost.
