The species is native to New Zealand and southern Australia, typically appearing near shorelines in the summer months (December - March).

The species follows a distribution pattern across the southern Pacific Ocean and can frequently be found in shallow coastal waters.

During this phase, larvae produced by mature jellyfish grow into small stalk-like figures that attach themselves to some kind of surface.

The buds grow into a fully mature diocious medusae jellyfish which can then utilize sexual reproduction to once again start the life cycle.

A single polyp is capable of producing as many as twelve medusae buds before its part in the life cycle ends.

This distribution is credited towards the polyps ability to latch on to a surface which can include vessels such as large international ships.

Because of this global distribution and the prehistoric phylogeny of the Hydrozoa family, researchers are still unsure where the exact origins of the genus may be.

Turritopsis dohrnii has the ability to revert its own lifecycle to avoid senescence and theoretically live forever under the right conditions.

This is especially common during the summer months between December and March because the jellyfish prefers warmer waters in a temperature range of 14 °C – 25 °.

Polyps can be commonly found around docks, marinas, vessels, and the ocean floor as long as their preferred pressure range is not exceeded.

The Turritopsis genus prefers similar conditions worldwide and has a slightly larger range of water temperatures that can be tolerated.

The size of each gathering depends on proximity, light, and food abundance and is full of male and female jellies.

Turritopsis rubra demonstrates a unique aspect of maternal care when the gathering ends as mothers will pick up any eggs they can and attach them at the base of their umbrellas.

These eggs will then form into larvae which stay with the mother until they have matured into polyps and can detach to find a suitable habitat.

In deeper waters, larger jellyfish and fish such as Tuna, Swordfish, and even some Shark species can hunt large swarms of Crimson Jellies.

Although the jellyfish has no defense mechanisms or behavioral patterns to defend itself, the speed of its reproduction abilities keep the Southeastern Pacific well populated.

The original genus of Turritopsis was thought to have been discovered and charted in 1895 but, without modern DNA sequencing, the individual species were almost impossible to tell apart.

Biological immortality is the ability to revert from a fully mature adult, medusae, to a juvenile form such as the polyp.

This process is also referred to as lineage reprogramming and is extraordinarily rare in the animalia kingdom because it involves skipping the intermediate steps between somatic cell transformation.

Because of the process of lineage reprogramming leaving no trace of past transdifferentiation, scientists have no way of knowing how long a jellyfish has been alive.
