Reported byNatural History Museum ↗·Sourced by Goodlede
The hydrozoan Turritopsis dohrnii, a jellyfish about 4.5 millimetres wide, can reverse its life cycle when physically damaged or stressed by shrinking into a blob-like cyst on the seafloor, then developing back into a polyp over 24 to 36 hours, with new adult medusae budding off afterward.
