The long tentacles of the compass jellyfish are coiled in a spiral and can cause skin irritation and irritation in humans due to their nettle poison. The tentacles are white, yellowish, orange and rarely brown.
Both sexes united
Compass jellyfish are hermaphrodites, that means there is a phase in their life when they have both sex organs. Initially, they develop the male organs and later have male and female sex organs at the same time. In this phase they can fertilize themselves. They hatch the eggs inside their body and then release the larvae into the open sea.
