The Sea Tomato is one of eight edible jellyfish species found in the eastern Indian Ocean.
This species can weigh up to 2.8 kg and the umbrella can reach 27 cm in diameter. There are eight main arms, each with 8 - 11 marginal lappets (hanging pieces of flesh). Each marginal lappet is relatively wide, with a rounded margin.
The Sea Tomato has 8 mouth arms which are the same, or slightly longer than the umbrella diameter.
Each mouth arm has several appendages, numerous long, narrow and filamentous, and a single small, club-shaped appendage.
The Sea Tomato can cause an annoying and painful, but not life-threatening sting.
