Humans have developed our own intricate coping strategies for managing this bleak biological reality–stretching back millenia. Some archaeological findings even indicate that human death rituals...
How does ocean acidification affect jellyfish? How do jetties affect coastal erosion? How do breakwaters affect coastal erosion? How does the carbon cycle affect ocean sedimentation? How does coral reef bleaching occur? Why are coral reefs an important aquatic ecosystem?
When an adult (medusa) immortal jellyfish is starved or injured, it reabsorbs its tentacles and transforms into its post-larval, benthic polyp. After sinking, its cells merge, losing their identities and turning into a blob-like cyst that has no resemblance to either a jellyfish polyp or me...
