Umbrella Jelly

Eutonina indicans

Eutonina indicans, commonly known as the Umbrella Jelly, is a small jellyfish that typically reaches a maximum size of about 3.5 cm. This species can be identified by its distinctive umbrella-shaped bell, which is characteristic of many jellyfish. It is often found in coastal waters, inhabiting the surface nearshore and on the continental shelf. The Umbrella Jelly is pelagic and can be observed at depths ranging from 0 to 100 meters, with a significant number of occurrences recorded shallower than 40 meters. It thrives in subtropical regions of the North Atlantic and North Pacific, often associated with habitats such as seagrass beds and subtidal rocks. Feeding primarily on invertebrate eggs and larvae, appendicularians, and small hydromedusae, the Umbrella Jelly plays a role in the marine food web. Its life cycle includes a meroplanktonic stage, and it is known to be abundant from spring to autumn. While specific details on its breeding habits are limited, it is noted that the species is listed only in its medusoid stage, indicating that it reproduces in this form. Diving encounters with the Umbrella Jelly can be intriguing, as divers may observe it drifting gracefully in the water column. Its presence at various dive sites makes it a relatively common sight during the warmer months. Conservation status for this species is currently not evaluated, indicating that further research may be needed to understand its population dynamics and potential threats.
