Lighthouse jellyfish are theoretically immortal creatures.

Reason: Method of reproduction

The lighthouse jellyfish can reproduce asexually from the polyp and is the only known organism that can revert from the sexually mature stage to the larval stage. It takes 25 to 30 days to reach sexual maturity in water temperatures of 20°C, and is characterized by the ability of sexually mature (capable of sexual reproduction) individuals to return to the polyp form.

Ordinary jellyfish will die after sexual reproduction, but the lighthouse jellyfish can return to the polyp form again. This is called differentiation transfer. Theoretically, there is no limit to the number of times this process can occur, and this jellyfish can achieve an unlimited lifespan through repeated normal reproduction and transdifferentiation. Therefore, it is also called the "immortal jellyfish". To be more precise, it should be "rejuvenation". Extended information

Introduction

Lighthouse jellyfish (scientific name: Turritopsis nutricula): It is a small jellyfish. The body is bell-shaped, about 4-5 mm in diameter. The body is transparent and the red digestive system can be seen. It looks like a lighthouse, hence its name. The stomach of the lighthouse jellyfish is huge and bright red, with a cross-shaped cross-section.

Distribution range

The lighthouse jellyfish is mainly distributed in the waters of the Caribbean. However, due to the discharge of ballast water from ocean-going ships, the lighthouse jellyfish gradually spread to other adjacent sea areas and spread to off the coast of Spain, Italy and Japan, and on the other side of the Atlantic - in the Panama region.
