The spotted jelly is a jellyfish with spots on the top of its bell, the rounded body. It lives in the warm Indo-Pacific oceans, and in some saltwater lakes in Palau and Indonesia. Its lake populations are famous because they have lost most of their sting.1

Ahabanza
Lives in the open ocean across the Indo-Pacific, and in marine lakes, which are saltwater lakes cut off from the sea. Some Palau populations gather in huge groups called smacks, which are tourist attractions. The best-known spot is Ongeim'l Tketau Lake in Palau, also called Jellyfish Lake.1

Irya iki?
Feeds on zooplankton and other tiny organisms, which it catches with its stinging cells. It also gets much of its nutrition from photosynthetic algae called zooxanthellae that live inside its tissues.1

Uko wayimenya

  • Distinctive spots on the top of the bell1
  • Colour ranges from greenish blue to olive green, from the algae living in its tissues1
  • Eight rhopalia (sensory organs) along the edge of the bell1
  • Eight frilled oral arms, each ending in a club-like appendage1
  • Numerous small mouths along the bottom of the oral arms, unlike many other jellies1

Imbaraga z'ubumara

Imirya itera urubori

Uturemangingo duto cyane ibihumbi dutera urubori turasa iyo hari ikidukozeho.

Ubumara bwayo bukora iki?

The venom is protein-based and is delivered by stinging cells called nematocytes (cnidocytes) on the upper surfaces of the oral arms. In jellyfish living in marine lakes, conditions in the lake are thought to break down this venom, so those populations do not sting humans.1

Iteje akaga kangana iki ku bantu?

Akaga ku bantu: YorohejeNko guterwa urubori n'uruyuki cyangwa munsi yaho. Mu by'ukuri ntacyo itwaye abantu.

Jellyfish in the open ocean have stinging cells on their oral arms. Populations in marine lakes, such as Jellyfish Lake in Palau, do not sting humans.1

Niba itera urubori

  • Sohoka mu mazi kandi ukureho imirya yayo (tentacles) yose ukoresheje uturindantoki cyangwa igitambaro.
  • Ku box jellyfish zo mu turere dushyuha: suka vinegere aho zateye urubori nibura amasegonda 30, hamagara ubutabazi kandi witegure gukora CPR (gukanda igituza no guhumekera umuntu). Ku bluebottle no ku zindi nyinshi: oza n'amazi y'inyanja, hanyuma ukoreshe amazi ashyushye kubera ububabare.

Buri gihe banza uhamagare nimero y'ubutabazi (112, 000, 911). Izi ni inama rusange z'ubutabazi bw'ibanze, si inama za muganga. Ibanze by'ubutabazi bw'ibanze

Irinde akaga

  • Ntuzigere ukora, ufata cyangwa ushotora inyamaswa yo mu gasozi, nubwo yaba ntoya, kandi nubwo yasa n'isinziriye cyangwa yapfuye.
  • Yihe umwanya. Niba uhuye n'imwe, tuza, usubire inyuma buhoro buhoro kandi uyireke yigendere.
  • Niba imwe igutereye urubori: tuza, ntunyeganyege, hamagara nimero y'ubutabazi (112, 000, 911) cyangwa ujye ku bitaro vuba. Ibuka uko yasaga, ifoto irafasha.

Ntigushakisha ngo ikugirire nabi. Ikoresha ubumara bwayo kugira ngo ifate ibyo kurya cyangwa yirinde, kandi ikunda cyane kwihisha. Ibindi ku kwirinda

Ibintu by'ukuri

1

Lake populations of spotted jellies have lost most of their ability to sting, probably after being cut off in marine lakes long ago.1

2

Each day, spotted jellies rise to the surface and follow the sun from east to west, so their algae can photosynthesise.1

3

Lake jellyfish are over three times wider than ocean ones, yet their tentacles are about the same length.1

4

Unlike many jellies, spotted jellies have several small mouths along their oral arms.1

5

A sea anemone called Entacmaea medusivora preys on spotted jellies, catching them in its tentacles.1

6

At night they stay lower in the water column.1

Usenya ibinyoma

Ikinyoma: All spotted jellies sting people.

Ukuri: Ocean populations have stinging cells, but the jellyfish in marine lakes such as Jellyfish Lake in Palau do not sting humans.1
