Description
editThe medusa of the white cross jellyfish is clear ranging from 3 to 5 cm (1.2 to 2.0 in) thick and 10 to 20 cm (3.9 to 7.9 in) wide.[1]
Visually it is very similar to Mitrocoma cellularia, but they tend to only grow up to 10 cm (3.9 in) in diameter.[2]
Distribution
editIt is found in cold water neritic zone including the North Atlantic Ocean, the North Sea, the Barents Sea, White Sea, and the Sea of Okhotsk,[1] and is found from May to early September.[3] The ecological niche is also present in the southern hemisphere around Antarctica, and spreading to southern South America,[4] and has been sighted in the Falklands[5] and Chile.[3]
Taxonomy
editIt was first described by J. F. Brandt in 1834 under the name Staurophora mertensii, but was re-described in 1995.[6]
