Chrysaora are a source of type II collagen, which is used in particular to relieve arthritis or joint pains.

The name of the jellyfish belonging to the Chrysaora genus comes from Chrysaor, the son of Medusa in Greek mythology.

These jellyfish are captivating, but when they appear in a massive group, this is a sign of climate disturbance.


This is the number of stinging cells (cnidocytes) on one millimetre of a tentacle of this jellyfish. Cnidocytes are used to paralyse prey.

Jellyfish reproduce sexually: the male and female gametes are produced by separate individuals. After fertilization has occurred between two individuals, small larvae known as planulae are born and deposited on the sea bed, where they become polyps. These polyps give birth to jellyfish through strobilation. This method of reproduction is characterised by vertical separation of parts which form small saucers and turn into jellyfish.
