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

홈

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

뭘 먹을까?

They mainly eat zooplankton, such as veligers, and also all forms of red drum larvae. They catch prey with their oral arms, which also help them move.1

알아보는 법

Dome-shaped bell that can reach 25 cm in diameter1
The rim of the bell is often coloured with brown pigment1
A cluster of oral arms under the body, extending out around the mouth1
Some related species found in the Pacific and South Atlantic are pale to blue in colour1

자주 헷갈리는 동물: Several undescribed Stomolophus species in the Pacific and South Atlantic have pale to blue pigment. They are genetically different from the cannonball jellyfish of the North Atlantic, but they are often misidentified as that species.1

독의 힘

쏘는 촉수

이 독(물거나 쏘는 독)은 어떤 작용을 할까?

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

사람에게 얼마나 위험할까?

사람에게 위험한 정도: 약함벌에 쏘인 정도거나 그보다 덜해. 사람에게는 거의 무해해.

Cannonball jellyfish are mostly harmless to people. Contact usually causes slight itching or minor eye irritation. They are among the most common causes of minor stings in US and Caribbean waters. Their toxin can cause heart problems in animals and humans, but this does not usually happen.1

무서울 때 어떻게 할까?

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

쏘면

물 밖으로 나와서 촉수를 떼어 내(장갑이나 천으로).
열대 상자해파리일 때: 쏘인 곳에 식초를 최소 30초 동안 붓고, 도움을 부르고, 심폐소생술(CPR)을 할 준비를 해. 작은부레관해파리와 대부분의 다른 해파리일 때: 바닷물로 헹군 다음, 통증에는 뜨거운 물을 써.

알아 둘 만해

사실

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

오해 바로잡기

오해: Cannonball jellyfish are dangerous to people.

진실: They are mostly harmless to people. Contact usually causes only slight itching or minor eye irritation.1

독 전문가를 위해

학명: Stomolophus meleagris
무리: 해파리와 쏘는 바다 생물
가족: Stomolophidae2
정렬: Rhizostomeae
대륙: 대서양, 카리브해, 멕시코만, 캘리포니아만, 대양
아기: They can reproduce sexually or asexually. Sexual reproduction happens when a cannonball shoots sperm from its mouth and another cannonball catches it. The embryos develop in pouches on the oral arms, then the larvae settle on hard surfaces and grow into polyps.1
