Diet
Turritopsis dohrnii are a carnivorous species that commonly feeds on zooplankton. T. dohrnii ingests food and excrete any waste through the mouth. T. dohrnii hunts by using its tentacles as it drifts through the water. It's tentacles, containing stinging cells (nematocysts), then spread and sting its prey. The tentacles can then flex to direct its prey to the mouth. T. dohrnii like other jellyfish may use its bell to catch its prey. T. dohrnii's bell will expand, sucking in water, as it propels itself to swim. This expansion of the bell brings potential prey in closer reach of the tentacles.

Predation
Turritopsis dohrnii like other jellyfish are preyed most commonly by other jellyfish. Other predators of T. dohrnii include, sea anemones, tuna, sharks, swordfish, sea turtles, and penguins. Many species prey on T. dohrnii and other jellyfish due to their simple composition. They are only approximately 5% matter and the remaining part is composed of water. They are composed of three layers. An outer layer (the epidermis), a middle layer (mesoglea; a thick, jelly-like substance), and an inner layer (gastrodermis).

Habitats
Turritopsis dohrnii was first discovered in the Mediterranean Sea, but has since spread worldwide. T. dohrnii generally found living in temperate to tropic waters. They have been found in marinas or docks, vessel hulls, and at the bottom(ocean floor). They typically live in a salinity range of polyhaline (18-30 PSU) and euhaline (30-40 PSU).
