The cannonball jellyfish is a round, dome-shaped jellyfish that looks a bit like a cannonball. It lives in warm coastal waters on both sides of the Americas and in parts of Asia, and it is common in shallow water near the coast. It matters because it is one of the most common causes of minor jellyfish stings in US and Caribbean waters.1

They live in shallow inshore waters. On the southeast coast of the United States they are extremely abundant in the summer and fall, when they make up over 16% of the biomass in shallow inshore areas. This is when people are most likely to meet them while swimming.1

Apa efek bisanya?

They release a mucus from their nematocysts (stinging cells) that contains a toxin when disturbed. The toxin can cause irregular heart rhythms and problems in the heart's conduction pathways, although this is not common in people. Contact with the nematocysts can be very painful and may cause redness and swelling, and the toxin is also harmful to the eyes.1

Apa yang dilakukannya saat takut?

When disturbed, they release a toxic mucus from their nematocysts, which harms small fish nearby and drives away most predators.1

Fakta

Juvenile portly spider crabs often live in the bell, eating some of the food the jellyfish catches. The jellyfish is not harmed because it can regenerate its tissue. One jellyfish has been seen with up to ten crabs in its bell.1

Jellyfish are commercially harvested as food. In Georgia, jellyball fishing is the state's third largest commercial fishery.1

The endangered leatherback sea turtle is one of their main predators.1

In 2012, El Golfo de Santa Clara in Mexico harvested 20,000 tons of these jellyfish from late April to early July.1
