Staurostoma falklandica

Staurostoma falklandica is very similar to the related White cross jellyfish, with the distinguishing feature being the much more diminutive second set of tentacles.^[3]: 236

It has a thin umbrella, measuring 90mm in diameter, with a stomach in four radiating arms across it. The mouth is the same length as the stomach, and its edges are a complicated series of folds. The gonads are along the edge of the stomach in deeper folds.^[3]: 235

There are several hundred principle tentacles closely packed round the edge of the bell. In between each pair of tentacles is a much smaller tentacle, similar in shape. Between the smaller and larger tentacles is a cordylus (sensory club).^{[4][3]: 236}

Staurostoma falklandica is a marine species which inhabits the southern hemisphere near Antarctica. Observations have been made in Chile, Argentina, Australia and New Zealand.^[2]
