The Comb Jelly is a hermaphrodite, found, in almost every ocean of the world. Their body is made up of "comb rows" eight rows of ciliary (hair) plates, used for propulsion, these generate the beautiful rainbow colours!
Despite its delicate and perhaps innocent appearance, the sea gooseberry is a voracious predator. Two retractable tentacles, sometimes reaching a length of 20 times the body diameter, are used to catch any prey that floats by! Unlike a jellyfish, comb jellies have no poison to paralyze their prey.
They in turn, are preyed on by crustaceans.
