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

Que come?
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

Como recoñecelo

  • 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

Adoita confundirse con: 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

Poder da pezoña

Tentáculos que pican

Miles de pequenas células urticantes disparan cando algo as toca.

Que fai a súa pezoña?

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

Que perigoso é para as persoas?

Perigo para as persoas: LeveComa unha picadura de abella ou menos. Practicamente inofensivo para as persoas.

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

Que fai cando ten medo?

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

Se pica

  • Sae da auga e quita os tentáculos que queden (con luvas ou cun pano).
  • Para as cubomedusas tropicais: bota vinagre nas picaduras durante polo menos 30 segundos, pide axuda e prepárate para facer a RCP. Para as carabelas portuguesas e a maioría das outras: aclara con auga de mar e despois con auga quente para a dor.

Chama sempre primeiro ao teu número de emerxencias (112, 000, 911). Isto son consellos xerais de primeiros auxilios, non consello médico. Primeiros auxilios básicos

Mantente a salvo

  • Nunca toques, collas nin molestes un animal salvaxe, aínda que sexa pequeno e aínda que pareza durmido ou morto.
  • Déixalle espazo. Se atopas un, mantén a calma, recúa amodo e déixao ir polo seu camiño.
  • Se un te pica: mantén a calma, non te movas, chama ao teu número de emerxencias (112, 000, 911) ou vai rápido a un hospital. Lembra como era, unha foto axuda.

Non vai a por ti. Usa a súa pezoña para cazar comida ou para defenderse, e prefire con moito agocharse. Máis sobre como estar a salvo

Datos

1

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

2

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

3

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

4

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

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
