Porpita porpita

Porpita porpita
Blue button

Mild stinging


It is a mild-stinging species and therefore with little or no effect on humans. Even so, it is recommended not to touch it since it may produce some type of dermal reaction after the contact in very sensitive persons.


The life cycle stage often seen of Porpitaporpita is not the free-swimming jellyfish but a floating colony of specialized polyps. It consists of two parts: a float and a colony of hydroids. The float is hard golden brown, full of gas in the center, and surrounded by intense blue hydroids, purple or yellow, that look like tentacles. The colony is formed by individual polyps and specialized each in a given function, such as feeding, defense or reproduction. They can measure up to 5 cm.


Along the Catalan coast this species is very rare, usually observed during the spring season.

Distribution and Habitat

It is found in warm waters of Europe, in the Gulf of Mexico, in the Mediterranean, New Zealand, and in southern waters of the USA. These animals live on the surface of the open sea, but occasionally they can be dragged to the coast in large quantities.
