[1] The earliest specimen of Marivagia stellata was collected off the coast of Tel Shikmona, at the southern entrance to the port city of Haifa, in 2006.

A larger specimen was collected at nearby Bat Galim on June 29, 2010, while a smaller one was found at Beit Yanai on July 7.

[1][2] Star-shaped and with a diameter of about 15 centimeters,[2] M. stellata is "life translucent bluish-white jelly, with conspicuous pattern of reddish stars, dots and streaks clustered in centre third of exumbrella".

[1] The coast of the southeastern Levant has been inundated by alien biota and it is unlikely that M. stellata, markedly different from all known scyphozoans in the Mediterranean, is a native species.

The identification of sexually mature specimens, in both winter and summer, and at sites nearly 90 km apart, suggests a local population has been established.
